Abstract
Abstract A method for producing a decorative design on a substrate by applying to the substrate an embossable coating comprising a filler, a binder, a release agent, a moisture control agent, and a liquid; drying the applied coating to remove a major portion of the liquid therefrom, sufficient liquid being retained to make the coating pliable and readily impressible by an embossing means; and subjecting the pliable coating to pressure contact with the embossing means, which is at ambient or an elevated temperature, to impress a decorative design into the coating; and the embossed coated substrate produced by the method.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
204 words
An embossable coating composition for application to a surface of a substrate at a rate of 25 to 150 grams per square foot of said surface comprising a filler selected from the group consisting of talc and filler mixtures comprising a major proportion of talc, a film-forming binder adapted to bind the filler particles together and to adhere said filler to said substrate, a moisture control agent wherein said moisture control agent is a member selected from the group consisting of propylene glycol, ethylene glycol, diethylene glycol, hexylene glycol, glycerol and combinations there of a release agent, and a liquid, wherein the quantity of said moisture control agent is sufficient to promote controlled moisture evaporation from said composition, whereby said composition is capable of (a) being dried to remove a major portion of said liquid therefrom but to leave sufficient liquid in said composition to render said composition pliable and readily impressible by an embossing means, and (b) being subjected, when said composition is in said pliable and readily impressible condition, to pressure contact with said embossing means to thereby emboss said composition; and wherein the quantity of said release agent is sufficient to render said embossed composition cleanly separable from said embossing means.
Claim 2
Dependent Claim
204 words
An embossable coating composition for application to a surface of a substrate at a rate of 25 to 150 grams per square foot of said surface comprising a filler selected from the group consisting of talc and filler mixtures comprising a major proportion of talc, a film-forming binder adapted to bind the filler particles together and to adhere said filler to said substrate, a moisture control agent wherein said moisture control agent is a member selected from the group consisting of propylene glycol, ethylene glycol, diethylene glycol, hexylene glycol, glycerol and combinations there of a release agent, and a liquid, wherein the quantity of said moisture control agent is sufficient to promote controlled moisture evaporation from said composition, whereby said composition is capable of (a) being dried to remove a major portion of said liquid therefrom but to leave sufficient liquid in said composition to render said composition pliable and readily impressible by an embossing means, and (b) being subjected, when said composition is in said pliable and readily impressible condition, to pressure contact with said embossing means to thereby emboss said composition; and wherein the quantity of said release agent is sufficient to render said embossed composition cleanly separable from said embossing means.
