An improved ink-receptive sheet comprising a substrate bearing on at least one major surface thereof an ink-receptive layer which comprises at least one ink receptive polymer and an effective amount of polymeric mordant having the general structure: onsisting of a COO-alkylene group having from 1 to about 5 carbon atoms, a CONH-alkylene group having from 1 to about 5 carbon atoms, -COO-(CH2CH2O)n-CH2-, -CONH-(CH2CH2O)n-CH2- and +545 CH2CH2NH2Cl+546 n, wherein n is from 1 to about 5; E and D are independently selected from the group consisting of alkyl group having from 1 to about 5 carbon atoms; or A, E, D and N are combined to form a heterocyclic compound selected from the group consisting of <IMAGE> R1 and R2 are independently selected from the group consisting of hydrogen, phenyl, and an alkyl group containing from 1 to about 5 carbon atoms; R is selected from the group consisting of hydrogen, phenyl, benzimidazolyl, and an alkyl group containing from 1 to about 5 carbon atoms, y is selected from 0 and 1, and X1 and X2 are anions.
