An ink composition for use in printing sheets including a binder, a wet print bleed control additive and a colorant. The composition may also contain a surfactant, an opacifier as well as a preservative. The ink composition may be used as a film or applied to a printing sheet backing to provide a printing sheet for making prints. Also, printing plates, having pieces of varying colored printing sheets are disclosed for creating multi-colored prints. Also disclosed is a process for making such printing sheets and a process for making a print with such printing sheets. These compositions are non-toxic and multi-colored prints can be easily made by a child using the disclosed printing sheets and plates.

A drawing device for providing entertainment as well as promoting the development of children, including a plurality of drawing instruments, such as crayons, a drawing instrument detector for determining the color of the particular crayon selected for use, a pressure sensitive drawing tablet that is responsive to pressure contact from the drawing instrument, and a computer that is adapted drive an audible device, such as a speaker, to generate various audible output, including both speech and melody which, in a preferred embodiment, may vary depending upon movement from the drawing instrument. Various uniquely identified drawing sheets, which may be preprinted with a wide variety of scenes, are included to directly insert into the device and overlay the drawing tablet. In connection with these drawing sheets, the computer may be adapted to further vary the audible output of the speaker dependent upon the identity of the particular drawing sheet that is inserted.

A multiple coloring composition system is disclosed whose coloring effect is changed upon treatment with a second coloring composition, once the second coloring composition has been deposited over the undercolor coloring composition. The multiple ink system comprises:
(a) an undercolor aqueous coloring composition comprising an undercolor dye whose coloring ability is destroyed in the presence of a pH of about 10 or greater and/or by a reducing agent; and (b) an overcolor aqueous coloring composition comprising a colorant capable of maintaining its characteristic color in the presence of a pH of about 10 or greater and/or a reducing agent, a base in an amount sufficient to yield a pH of the overcolor composition of about 10 or greater, and/or a reducing agent.
wherein X is a member selected from the group consisting of N, O and S; R 1 and R 2 are independently a straight or branched, saturated or unsaturated non-aromatic hydrocarbon of four to eighteen carbon atoms; m is 1 or 2; and n is 0, 1 or 2; and (b) a compound selected from the group consisting of primary, secondary, tertiary and higher amines, which are liquid at room temperature.
The reaction product of the present invention has excellent surfactant properties, and is suitable for use in coloring compositions to improve the fugitivity from skin and clothing. The reaction product is also useful as a cleansing agent.

The portable easel (100) includes a viewable storage compartment for enclosing and transporting artist supplies and drawing materials. The ,portable easel includes an upper housing portion (110) hingedly attached to a lower housing portion (112) so as to be movable between an opened position and a closed position. The storage compartment is formed into the lower housing portion. In the opened position, the upper housing portion is positioned at an inclined angle with respect to the lower housing portion thereby providing an inclined drawing surface. In the closed position, the upper housing portion overlays the lower housing portion so as to enclose the storage compartment formed therein. To facilitate viewing of the storage compartment when the upper housing portion is in the closed position, the upper housing portion or a section thereof is formed from transparent or translucent plastic.
摘要:
A washable dry erase coloring composition comprising an acid dye or polymeric dye colorant, a dye vehicle, a release agent, and an anionic dyeblocker. The dyeblocker additive may be an aromatic organic sulfonate and, preferably, is either a sulfonated naphthalene condensation product or a sulfonated phenol-formaldehyde condensation product. The dry erase coloring composition is suitable for use in marking on a whiteboard and enhances fugitivity from skin and fabrics. The dry erase coloring composition may optionally contain a film forming resin. More specifically, the invention is, in one preferred embodiment, a washable erasable whiteboard marker ink comprising an acid dye or polymeric dye, water, a film forming resin, a release agent and an aromatic organic sulfonate. In addition, the invention also includes a method of transferring an image from a whiteboard or non-porous surface to paper. This method comprises the steps of: (a) drawing an image on a whiteboard or non-porous surface with a washable coloring composition containing a dyeblocker; (b) applying a moistened paper to the image; (c) rubbing the moistened paper to transfer the image from the whiteboard to the paper; and (d) removing the paper.
