<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 general structure (I) wherein A is selected from the group consisting of a COO-alkylene group having from 1 to 5 carbon atoms, a CONH-alkylene group having from about 1 to 5 carbon atoms, -COO-(CH2CH2O)n-CH2- and -CONH-(CH2CH2O)n-CH2-, wherein n is from 1 to 5; B and D are independently selected from the group consisting of alkyl group having from 1 to 5 carbon atoms; or A, B, D and N are combined to form a heterocyclic compound selected from the group consisting of (II) and (III); R1 and R2 are independently selected from the group consisting of hydrogen, phenyl, and an alkyl group containing from 1 to 5 carbon atoms; R is selected from the group consisting of hydrogen, phenyl, benzimidazolyl, and an alkyl group containing from 1 to 5 carbon atoms, y is selected from 0 and 1, and X1 and X2 are anions.</p> |
