Abstract: Multiple ply labels include removable single ply portions for use in facilitating package shipment operations. Two-ply and a three-ply embodiments are disclosed with release material being applied to portions of a second or bottom ply which are overlain by tab portions of a first or top ply having adhesive applied to the underside of the tab portions and around the periphery of the top and bottom plies to adhere the plies to one another to assemble the labels. The tab portions are preferably formed by die cuts; however, lines of weakness created for example by creasing or lines of perforations can be used to make the tab portions readily separable from the top ply. Card portions are also formed by lines of perforations or other lines of weakness in the top ply with the card portions being formed clear of any adhesive coating such that they are free of adhesive for filing, mailing or other applications related to the package shipment operations.

Abstract: An improved security document according to the present invention includes a substrate having a surface for carrying indicia. The document has background printed matter, consisting of a pattern of elements of a first size and frequency, printed at a first density on the surface. The document further has a cancellation term, consisting of a pattern of elements of a second size and frequency, printed at a second density on the surface. Elements of one of the first size or the second size are sufficiently small such that they are not reproduced by a color copier at a particular copier setting, and elements of the other of the first size or the second size are sufficiently large such that they are reproduced by the color copier at the particular copier setting. As a result, a copy of the security document made on a color copier displays the cancellation term. At least a portion of the security document surface is divisible into a plurality of bands extending across the surface.

Abstract: A mailer or business form is provided including a coating of a first colorless reactant on one sheet thereof and a transparent patch overlying the coating.

The various embodiments of the invention also include both preprinted information as well as the capability to record variable information on more than one ply in a single printing pass.

Abstract: Carbonless coating compositions which can be printed onto one or more sheets of a business form or mailer to provide a visible image which is sharper and darker than previous coatings are provided. The compositions also find use on security documents and safety papers to provide a covert image on the document beneath information which may be subject to attempted alteration, such as the amount written on a check. The covert image becomes visible upon the application of pressure or solvent in the area coated to provide evidence of the attempted alteration. The self-contained composition includes an admixture of a color former, a color developer, and a plurality of pressure-rupturable microcapsules containing a solvent. Another solvent-sensitive composition includes an admixture of a color former and a color developer.

Abstract: A high solids content, aqueous, microcapsule-containing printing ink is prepared by forming microcapsules in situ in a printing ink vehicle. The microcapsules are preferably prepared by interfacial polymerization or interfacial crosslinking between a reactant, such as a polyisocyanate dissolved in an oily solution and a coreactant such as a polysalt of casein and diethylene triamine present in an aqueous solution into which the oily solution is dispensed. The aqueous solution contains water and preferrably a non-volatile diluent such as a non-reducing sugar, for example methyl glucoside. The oil-containing microcapsules contain an oil solvent and a mixture of dye precursors which upon reaction with a color developer produces an intense black image. The printing ink preferably has a 60-70% by weight solids content and may be used as a low-coat-weight CB coating for preparing carbonless copy paper.

A mixture of radiation curable oligomers, monomers, and optionally a free radical initiator are blended together, coated onto a substrate, and then cured. Other optional components in the coating include an adhesion promoter, coloring agents, pigments, and/or fillers.

Abstract: A document is provided having a solvent sensitive and/or pressure sensitive ink printed thereon which reacts to the application of a solvent and/or pressure to form a visible stain or image. The ink includes a first composition of solvent soluble, water insoluble dye particles, a binder, and optionally, an opacifier. Alternatively, the first composition may be combined with a second composition which includes an encapsulated solvent and optionally a stilting material. The first and second compositions may be printed on the document in separate steps or printed together as a self-contained composition. The ink may be printed on the entire surface of the document or only on selected areas thereof.

The mixture containing these components is reacted to form microcapsules containing the core material. The tertiary aliphatic isocyanate preferably comprises an adduct of m-tetramethylxylene diisocyanate and trimethylolpropane. The core material may contain a dyestuff precursor which is capable of reacting with a color developer to form a color. The microcapsules containing dyestuff precursor may be used to coat a support sheet to form carbonless copy paper.

Abstract: A process for producing melamine-formaldehyde microcapsules using a reactive protective colloid is provided. The reactive protective colloid is prepared by reactively coupling a surface active polymer with a first melamine-formaldehyde pre-condensate. An aqueous solution which includes the reactive protective colloid and a second melamine-formaldehyde pre-condensate is then prepared. A substance to be encapsulated, preferably an oily solution containing a dyestuff precursor, is dispersed as droplets into the aqueous solution. The reactive protective colloid surrounds the droplets to form an emulsion. The second melamine-formaldehyde pre-condensate and the reactive protective colloid are made to self-condense to form melamine-formaldehyde microcapsule walls around the droplets of the substance to be encapsulated.

Abstract: An improved security document which protects documents from copying on color copying machines. The document has cancellation terms and background pattern in two tones. If the copier is adjusted to obscure the cancellation term on reproduced copies at one tone, the cancellation at the other tone will appear. In an alternative embodiment, the density of the cancellation term and the background pattern vary across the face of the document. In this case, the cancellation term will appear somewhere on the copy no matter what copier adjustments are made.

The ink includes from about 25 to 35% of a non-volatile oil, 25 to 35% of an acidic color developer, 20 to 50% filler, and 4 to 15% dispersed wax particles, all percentages by weight.

Abstract: A security, information document for providing information to a reader from an information source organization includes a document substrate having a first area in which a half-tone warning image is printed, indicating that a copy of the document is an unauthorized document. A half-tone background image is printed in a second area on the substrate, with the second area surrounding the first area. A camouflage image extends over the document substrate for confusing the eye of an observer such that the warning image is not readily observed. One of the half-tone warning image and the half-tone background image is printed with a half-tone screen of such a line spacing that it is not readily reproducible by a copier. The camouflage image may contain an identification of the source of the information.
