Thermal transfer articles of the invention comprising a carrier, optionally a release layer, a color layer releaseably adhered thereto, and optionally an adherence layer on the bottom side of the color layer. Also methods for thermal transfer using such articles and signage made by such methods. The transfer articles of the invention 1) exhibit thermoplastic, low cohesive properties during transfer such that good image resolution and transfer is achieved and 2) are thermally crosslinked such that a durable image is formed.

[ What is claimed is:] [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,

[ What is claimed is:] [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: [ STR 3 ] 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.
