<p>An improved ink-receptive sheet comprising a transparent substrate bearing on at least one major surface thereof an ink-receptive layer which comprises at least one imaging polymer and an effective amount of polymeric mordant having the general structure: <IMAGE> wherein A is selected from the group consisting of a COO-alkylene group having from about 1 to about 5 carbon atoms, a CONH-alkylene group having from about 1 to about 5 carbon atoms, -COO-(CH2CH2O)n-CH2- and -CONH- (CH2CH2O)n-CH2-, wherein n is from about 1 to about 5; B and D are independently selected from the group consisting of alkyl group having from about 1 to about 5 carbon atoms; or A, B, D and N are combined to form a heterocyclic compound selected from the group consisting of <IMAGE> <IMAGE> R1 and R2 are independently selected from the group consisting of hydrogen, phenyl, and an alkyl group containing from about 1 to about 5 carbon atoms; R is selected from the group consisting of hydrogen, phenyl, benzimidazolyl, and an alkyl group containing from about 1 to about 5 carbon atoms, y is selected from 0 and 1, and X1 and X2 are anions.</p> |
