Abstract: A direct image-recording material has a layer of a thermosensitive layer formed on a thin substrate. The substrate comprises an organic polymeric material that is substantially transparent and colorless and has a thickness no greater than about 10 .mu.m. Preferred embodiments of the invention further include a support sheet with an interposed first adhesive layer on the thermosensitive composition layer. Other preferred embodiments further include a second adhesive layer and a backing sheet, which may be releasable, on the support sheet.

Abstract: An acceptor material for printing by ink-jet primers forms water-resistant, light-stable ink records with aqueous ink jet inks. The material comprises a support such as polyester film and a coating containing a water-soluble phospholipid mordant that forms insoluble compounds with and immobilizes the dyestuffs of the ink jet inks and a water managing polymer, preferably, hardened gelatin, which quickly renders the material dry-to-the-touch after contact with the aqueous ink.

Abstract: Rolls of heat-printable material have heat-printed end warning stripes for several feet along the edges of the material at the end of the roll. The stripes are formed by pressing a heated roller into contact with the material as it is slit and wound on take-up cores during manufacture.

Abstract: The present invention is directed to a heat-sensitive imaging material that comprises a support on which is formed a heat-sensitive imaging layer. This imaging layer comprises a color-forming amount of a substantially colorless, finally divided noble metal salt of an organic acid, an organic reducing agent that is capable of a color-forming reaction with the noble metal salt under heating conditions to produce a colored image, and a stabilizer compound of formula (I) that mitigates the formation of non-imaging background color in the imaging layer: ##STR1## In formula (I), Z.sub.1, Z.sub.2, and Z.sub.3 each independently represents hydrogen, an alkali metal ion, an alkyl group comprising 1 to about 8 carbon atoms, an aralkyl or cycloalkyl group comprising 5 to about 10 carbon atoms, or an aryl group comprising 6 to about 15 carbon atoms; or Z.sub.1 and Z.sub.

Abstract: A ring binder holder for transparency sheets comprises an elongated, rectangular ring-engagable strip of sheet material such as plastic or heavy paper having two parallel longitudinal edges. A line of ring-engagable openings in the strip is parallel and adjacent to one of the edges. Along the other edge is a line of adhesive on the strip that is adapted to adhere and attach the strip to an edge of a plastic transparency sheet. An elongated opaque flap is hingedly attached to the strip along a line that extends the entire length of the strip between and parallel to the line of ring-engagable openings and the line of adhesive. The flap is hingedly movable between a closed position covering the adhesive line and an open position covering the ring-engagable openings and the adjacent edge of the strip.

Abstract: An acceptor material for printing by ink-jet printers forms water-resistant, light-stable ink records with aqueous ink jet inks. The material comprises a support such as polyester film and a coating containing a water-soluble high molecular weight amino compound that forms insoluble compounds with and immobilizes the dyestuffs of the ink jet inks and a water managing polymer, preferably, hardened gelatin, which quickly renders the material dry-to-the-touch after contact with the aqueous ink.

Abstract: A toner receiver sheet having excellent adhesion to toner particles, optical clarity and physical properties that reduce or eliminate sheet feeding problems in automatic copying machines is prepared by coating on a plastic support a thin layer of a dilute aqueous colloidal solution of an acrylic polymer, an electrically conductive organic compound and a small concentration of transparent, non-light scattering polysiloxane beads. The coating is dried and cured to form on the support a water-insoluble acrylic layer of less than 2 .mu.m thickness and affixed thereto a distribution of widely spaced apart transparent polysiloxane spherical beads of 10 to 15 .mu.m diameter.

Abstract: An acceptor material for printing by ink-jet printers forms quick-drying, water-resistant, light-stable ink records with aqueous ink jet inks. The material comprises a support such as polyester film and a coated layer containing a water-soluble mordant that forms insoluble compounds with and immobilizes the dyestuffs of the ink jet inks and a hardened water managing polymer, preferably, hardened gelatin, which contains polymeric beads that protrude from the layer.

Abstract: A heat-sensitive coating composition, and heat-sensitive material for thermal imaging containing the heat sensitive composition. The composition comprises a color-forming amount of a finely divided, solid, colorless noble metal salt of an organic acid; a color-developing amount of an organic reducing agent which at thermal copy and printing temperatures is capable of a color-forming reaction with the noble metal salt; an image toning agent; and a carrier composition in which the noble metal salt, organic reducing agent, and toning agent are distributed. The carrier composition requires no organic solvents and comprises one or more substantially water-soluble polymeric carrier materials and a solubility-enhancing amount of a dispersing agent. A protective, clarifying, radiation-cured overcoat is provided. Methods of forming the heat-sensitive composition and the overcoat are also disclosed.

Abstract: An improved heat sensitive coating composition and heat sensitive paper for thermal printing containing the composition are disclosed. The composition contains a color-forming amount of a finely divided solid colorless or pale colored chromogenic fluoran dyestuff, a color-developing amount of a finely divided mixture of benzyl p-hydroxy benzoate and a halogenated derivative of 4,4'-isopropylidenediphenol and a carrier composition.

Abstract: A heat-sensitive coating composition for a thermo-responsive printing or recording record material for thermal printing devices comprising a color-forming amount of a finely divided solid chromogenous basic 3, 3-bisarylphthalane derivative, and a color-developing amount of a finely divided solid phenol derivative which at thermal printing temperature is at least partially fluidizable and capable of a color-forming reaction with the chromogenous 3,3-bisarylphthalane derivative distributed in a carrier composition comprising a substantially water soluble anionic polysaccharide gum and a stability enhancing amount of sucrose benzoate.

Abstract: A color forming heat sensitive coating composition comprising a color forming amount of a finely divided homogenous basic 3,3-bisarylphthalane derivative and a color developing amount of a finely divided solid phenyl derivative which at thermal printing temperature is at least partly fluidizable and capable of a color forming reaction with said 3,3-bisarylphthalane compound dispersed in a polyvinyl alcohol carrier is disclosed wherein the improvement comprises the addition of an anti-sticking amount of a functional filler which may be a di(lower alkyl)dithiocarbamate or lower alkylxanthate of lead, zinc, cadmium and alkaline earth metals or a tetra (lower alkyl)thiuram disulfide or a di(lower alkyl) xanthogen.
