Abstract: A washable 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 washable multiple ink system comprises:(a) an undercolor aqueous coloring composition comprising a compatable surfactant in an amount sufficient to provide washability and 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 compatable surfactant in an amount sufficient to provide washability, 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.

Abstract: A multiple coloring composition system for use on non-porous surfaces 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 a film forming resin and 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 film forming resin, 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.

Abstract: A color-changing marking composition system, suitable for use in the form of crayons and pencils, comprising a first marking composition comprising wax, a dye, which is other than a Leuco dye and which is capable of changing color upon contact with a color change-inducing compound, and a solvent capable of solubilizing the dye; and a second marking composition comprising wax and a color change-inducing compound, which is capable of inducing a color change in a dye in a marking composition with which it is brought in contact.

Abstract: 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.

Abstract: A thermochromic drawing device is disclosed which can be marked and erased by selectively changing the temperature of its drawing surface. The drawing surface of the drawing device consists of a flexible substrate printed with thermochromic inks having at least two color states. The flexible substrate has low thermal mass thereby enabling it to readily assimilate temperatures induced by a user and, consequently, facilitating the transition of the thermochromic inks from one color state to another. The drawing surface is further provided with an insulating layer which isolates the flexible substrate from unwanted heat sinks and heat sources thereby preventing unwanted color transitions of the thermochromic inks. Thus, a user can selectively change the color state of portions of the drawing surface to create distinctive markings.

Abstract: A portable writing instrument container is disclosed for holding, transporting and storing writing instruments in the shape of a vehicle, such as a bus or locomotive. The container consists of a lower housing, an upper housing, a sharpener and a plurality of compartments for holding a plurality of writing instruments. The upper housing is removable to allow access to the compartments and the writing instruments. The container has functioning wheels to facilitate the playfulness of the container. In operation, the functioning wheels provide the ability to transport the container along a surface. In addition, a kit includes the writing instrument container and writing instruments which are packaged in an enclosure for shipment to the customer.

Abstract: A molding device to make molded items from molding compound is provided. The device includes a first mold insert which corresponds to a first portion of a molded item and a first mold insert holder removably holds the first mold insert. A second mold insert is provided which corresponds to a second portion of the molded item and a second mold insert holder is provided which removably holds the second mold insert. The first and second insert holders are connected at one end by a living hinge and a handle extends from the opposite of the first and second holders. In a preferred embodiment, a twist lock is provided for securing the inserts to the insert holders.

Abstract: A device for providing support for drawing media is provided. The device has a first support member, a second support member and one panel having a drawing face. The panel is supported by the first support member and the second support member. The panel has a drawing face oriented upwardly at an angle to the horizontal. The device can include a supply tray for storing drawing supplies. The device can also include a second panel having a drawing face.

Abstract: A writing kit comprises a base, an external wall extending in a direction generally perpendicular to the base to define a compartment, one or more wings hingeably mounted to the base, one or more writing surfaces attached to the interior wing surface of at least one wing, wherein the wings may be adjusted between an open position, one or more partially open positions, and one or more closed positions. Preferably, the kit includes four wings and four writing surfaces, one attached to each wing. The kit provides for self-contained storage of the writing surfaces and writing implements, and is suitable for use by a child.

Abstract: An erasable marking composition comprising a noncarboxylated styrene-butadiene copolymer resin, a colorant, and a solvent. The composition can be applied to substrates by a variety of delivery means, such as porous-tipped and brush-tipped writing instruments, as well as brushes, and can be easily erased with a substantially nonabrasive eraser, such as a common pencil eraser, for an extended period of time.
