Abstract: A latent image developing system, a novelty kit, and an ink composition for printing latent images on a substrate. The latent image developing system includes a first substrate containing a colorless image deposited on a first surface thereof. A developer component is provided that is reactive with the colorless image to provide a visible image. The developer component is selected from a developer instrument, a developer finger paint, a developer coating on a first surface of a substantially transparent substrate for adhesive attachment to the first substrate, and a combination of one or more of the developer instrument, the developer finger paint, and the developer coating. The latent image developing system optionally includes, an image blocking instrument for concealing at least a portion of the visible image. The image blocking instrument includes a blocking composition applicator and an aqueous mixture of blocking composition and water.

Abstract: The invention relates to a device for developing latent or hidden images. The device includes a first substrate containing a hidden or latent image printed on a first surface thereof, wherein the image contains one or more chromogenic compounds. A second substrate having a first surface contains a developer coating for developing the hidden or latent image. The developer coating includes a developer compound, a micro-encapsulated solvent, and an adhesive. Upon sufficient interfacial contact between the first surfaces of the first and second substrates, a visible image is produced. The device enables production of a relatively vibrant, full color images which are substantially non-toxic and relatively inexpensive to make.

Abstract: A scoop expandable into a configuration including a handle section attached to a bellows section. The bellows section includes a plurality of slant wall sections and thin wall sections attached between adjacent slant wall sections defining peaks and valleys between adjacent slant wall sections, and a center bottom section attached to an adjacent slant wall section. A height dimension of the scoop in an unexpanded state ranges from about 2.5 to about 12.5 millimeters. The scoop is suitable for use in packaging granulated materials under high speed, high pressure, or space-limited packaging conditions.

Abstract: A food package insert comprising a multi-part structure having at least one removable edge portion. The multi-part structure includes an oil and grease resistant cellulosic support web having first and second exterior surfaces, first and second facing interior surfaces, and a support web edge portion disposed adjacent the removable edge portion thereof. At least one hidden image is imprinted on one of the first and second facing interior surfaces. The hidden image is printed in a first color and a second color is imprinted over the first color in a pattern sufficient to substantially hide the hidden image. A colored film insert is attached to the fixed edge portion of the web between the facing first and second interior surfaces. The colored film insert is printed with the second color and is at least partially transparent for revealing a hidden image printed on one of the first and second interior surfaces.

Abstract: An in-line method for making a water-activatable laminate. The method includes providing a polymeric film having a first surface and a second surface. An opaque water activatable material containing from about 5 to about 40 wt. % pigment and from about 60 to about 95 wt. % binder is applied to the first surface of the film using an in-line coating technique selected from a flexographic coater, a rotary screen press, and a rotogravure coating technique. The coating is then dried to provide a single water activatable opaque layer having a thickness ranging from about 0.60 mil to about 2.0 mil. The binder for the opaque coating layer includes a mixture of solvent, butyl acetate, ethylene glycol monobutyl ether and propylene glycol. The laminate may be used multiple times without adversely affecting its ability to reveal and hide images.

Abstract: A laminate and a method for making a laminate having a hidden or shielded image. The laminate includes a substrate having an first surface containing an image thereon and a polymeric film laminated to the first substrate surface overlying the image. The film contains an exposed water activatable opaque layer having a thickness ranging from about 0.60 mil to about 2.0 mil, the opaque layer including aluminum silicate and a binder. Upon wetting the opaque layer, the hidden or shielded image is revealed. The method includes a means for producing the laminate in high volumes for minimizing the production costs thereof. Upon drying the opaque layer, the image is again hidden or shielded from view. The laminate may be used multiple times without adversely affecting its ability to reveal and hide images.

Abstract: The invention described in the specification relates to latent image printing and developing systems and to substrates containing latent images. High quality latent images are prepared by a printing method which deposits a layer containing organic-based dye particles and organic-based developer particles, each having a particle size of from about 2 to about 6 microns, on a substrate. The image is then developed by contacting the substantially invisible image of dye and developer particles with an oxygenated solvent from an imaging device. Multicolor, vivid images are obtained as a result of the image printing and developing system of the invention.
