Abstract
Abstract A process for repeatedly tinting and changing the color of solid materials which comprises applying a polymeric composition to the material and thereafter contacting the treated material with a dye which has a higher affinity for the polymeric composition than the material. In this manner the dye is temporarily fixed on the material and can be removed by washing in a detergent solution. The dyeing and removing steps can be repeated.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
19 words
The process of claim 1 wherein the polymeric composition is a basic polymer and the dyes are acid dyes.
Claim 2
Dependent Claim
19 words
The process of claim 1 wherein the polymeric composition is an acid polymer and the dyes are basic dyes.
Claim 3
Dependent Claim
24 words
The process of claim 3 wherein the acid is a synthetic acid polymer comprising at least 10 weight percent acid calculated as acrylic acid.
Claim 4
Dependent Claim
13 words
The process of claim 1 wherein the solid material is a textile fabric.
Claim 5
Dependent Claim
16 words
The process of claim 5 wherein the fabric comprises a blend of cellulosic and synthetic fibers.
Claim 6
Dependent Claim
12 words
The process of claim 6 wherein the synthetic fibers are polyester fibers.
Claim 7
Dependent Claim
23 words
The process of claim 4 wherein the acid polymer is prepared from a monomeric mixture comprising an acrylic ester and an acrylic acid.
Claim 8
Dependent Claim
28 words
The process of claim 8 wherein the monomeric mixture comprises from about 10 to 80 parts of ethyl acrylate and about 20 to 90 parts of acrylic acid.
Claim 9
Dependent Claim
34 words
The process of claim 3 wherein the acid polymeric composition also contains an aminoplast textile resin and a textile resin catalyst, and the coated material is subjected to textile resin curing conditions before dyeing.
Claim 10
Dependent Claim
66 words
The process as defined in claim 1 wherein said solid material comprises a fabric and wherein said fabric is coated with a synthetic acid polymer comprising at least 10 weight percent acid calculated as acrylic acid, the fabric is converted into a desired article, and thereafter, the coated fabric is contacted with a basic dye having a greater affinity for the polymeric composition than the fabric.
Claim 11
Dependent Claim
16 words
The process of claim 11 wherein the fabric comprises a blend of cotton and polyester fibers.
Claim 12
Dependent Claim
54 words
The process of claim 11 wherein the fabric initially is treated with an aminoPlast textile resin and a textile resin catalyst prior to the application of the acid polymer, and the fabric is subjected to textile resin curing conditions after application of the acid polymer or after formation of the article of wearing apparel.
Claim 13
Dependent Claim
16 words
The process of claim 13 wherein the textile resin is an acrylamide or an ethylene urea.
