Abstract
An ink composition is disclosed including a colorant and at least one polymer selected from the group consisting of polyvinylimidazole, derivatives of polyvinylimidazole, copolymers of vinylimidazole and copolymers of vinylimidazole derivatives. The present invention also relates to ink compositions including a colorant and at least one polymer selected from polyvinylpyridine, derivatives of polyvinylpyridine, copolymers of vinylpyridine and copolymers of vinylpyridine derivatives. Also disclosed is an ink composition comprising a pigment and at least one polymer selected from the group consisting of polyethyleneimine and derivatives thereof. Further disclosed is a method for generating printed images which include incorporating into a printing apparatus the ink compositions described above and generating an image onto a substrate.
