Abstract:
A radiation-crosslinkable thermoplastic composition comprising:(a) not less than 10 weight percent of the total weight of (a) and (b) of a dispersion of a copolymer within the general formula: ##STR3##wherein R.sup.1 is selected from the group consisting of H and alkyl groups containing one to eight carbon atoms; R.sup.2 is selected from the group consisting of H, alkyl groups containing one to six carbon atoms, --CN, ester groups, and R.sup.3 --COOH, wherein R.sup.3 is any alkyl group, e.g., containing from one to eight carbon atoms; X and Y are independently selected from the group consisting of a residue of the first ethylenically unsaturated monomer and a residue of the second ethylenically unsaturated monomer; n is a positive integer selected such that the first ethylenically unsaturated monomer provides from about 70 to 99 mole percent (48 to 97 weight percent) of the copolymer; and m is a positive integer selected such that the second ethylenically unsaturated monomer correspondingly provides from about 1 to 30 mole-percent (2 to 52 weight percent) of the copolymer, the formula including basic salts thereof;(b) at least 50 weight percent of the total weight of (a) and (b) of a polyurethane comprising a plurality of pendant radiation crosslinkable ethylenically unsaturated moities;(c) a colorant; and(d) a crosslinking agent.
