Kit comprising multicolored fluid dispenser markers together with eradicating fluid dispenser, stamps and stamp pad

Claim 1

A coloring kit which comprises in combination: means comprising a plurality of devices capable of producing a series of rainbow-colored marks or imprints, including at least each of the primary colors red, yellow and blue, each of said devices including a reservoir of a different colored water-based fluid consisting essentially of a common carrier solution composed essentially of 70-100% deionized water and from 0-30% glycols; a non-ionic wetting agent in concentrations of from about 0.125 to 0.25% by weight of said carrier solution; an antioxidant in concentration of from about 0-7% by weight of said carrier solution, and predetermined dye-stuffs in concentrations from about 0.125 to 3.25% by weight of said carrier solution; marking or stamping means operable in collaboration with each said reservoir of colored water-based fluid to produce a discernible colored mark on a smooth substrate; means comprising a single eradicator fluid formulated to eradicate any and all of the colors of said rainbow-colored marks or imprints produced by said marking devices, said eradicator means comprising a reservoir of a water-based eradicator fluid consisting essentially of about 65-95% of said common carrier solution, about 5-35% reducing agent and about 0.125 to 0.25% wetting agent; marking or stamping means operable in collaboration with said reservoir of said eradicator to produce an imprint of eradicator fluid on said smooth substrate; wherein said eradicator fluid is so formulated that upon application to said discernible colored marks said eradicator will remove the color therefrom without removing the color from or substantially staining the substrate.

Claim 33

The method of providing a kit comprising a plurality of reservoirs of water-based coloring fluid for different color markings and a reservoir of eradicating fluid which operates to eradicate the colored marks of each of said coloring dispensers, which comprises the steps of: mixing 70 to 100 weight percent water with 0 to 30 weight percent glycol to form a Solution A; combining said Solution A with a wetting agent in the amount of from 0.125 to 0.25 weight percent of Solution A thereby forming a common carrier solution; and for each of said coloring fluids: dissolving a quantity of each of a plurality of appropriately colored dyestuffs in said common carrier solution to form a plurality of colored mixtures and adding a portion of antioxidant to each of said mixtures; and for said eradicating fluid: dissolving a quantity of reducing agent in said Solution A in a ratio of from 5 to 35 parts of reducing agent for 95 to 65 parts of Solution A, and adding a wetting agent to said mixture in the amount of from 0.125 of 0.25 weight percent of Solution A.

Claim 34

The method of providing a kit comprising a plurality of reservoirs of water-based coloring fluid for different color markings and a reservoir of eradicating fluid which operates to eradicate the colored marks of each of said coloring dispensers, which comprises the steps of: mixing 70 to 100 weight percent water with 0 to 30 weight percent glycol to form a Solution A; combining said Solution A with a wetting agent in the amount of from 0.125 to 0.25 weight percent of Solution A thereby forming a common carrier solution; and for each of said coloring fluids: dissolving a quantity of each of a plurality of appropriately colored dyestuffs in said common carrier solution to form a plurality of colored mixtures and adding a portion of antioxidant to each of said mixtures; and for said eradicating fluid: dissolving a quantity of reducing agent in said Solution A in a ratio of from 5 to 35 parts of reducing agent for 95 to 65 parts of Solution A, and adding a wetting agent to said mixture in the amount of from 0.125 of 0.25 weight percent of Solution A.
