Claims
- 1. A thermally-crosslinkable thermoplastic composition comprising a dispersion of a color agent and a latent crosslinker in a copolymeric binder, said binder comprising the copolymerization product of an olefinic monomer and a second monomer having a pendant carboxyl group, the binder having the general formula: ##STR3## wherein R.sup.1 is independently hydrogen or an alkyl group containing one to eight carbon atoms; R.sup.2 is H, an alkyl group containing one to six carbon atoms, --CN, an ester group, or --R.sup.3 --COOH wherein R.sup.3 is any alkyl group; X and Y are independently a residue of the olefinic monomer or a residue of the second monomer; n is a number selected such that the olefinic monomer provides 70 to 99 mole percent of the binder; and m is a number selected such that the second monomer correspondingly provides 1 to 30 mole percent of the binder; the formula including basic salts thereof.
- 2. The composition of claim 1 wherein said olefinic monomer is ethylene and said second monomer is either acrylic acid or methacrylic acid.
- 3. The composition of claim 1 wherein said copolymeric binder is blended or supplemented with a secondary binder.
- 4. The composition of claim 3 wherein said secondary binder is an acrylic, styrenated acrylic, or polyurethane polymer.
- 5. The composition of claim 1 wherein said crosslinker is a covalent crosslinker.
- 6. The composition of claim 1 wherein said crosslinker is selected from the group consisting of melamine formaldehyde resins, carbodiimides, epoxies, and oxazolines.
- 7. The composition of claim 6 wherein said crosslinker is a melamine formaldehyde resin.
