Abstract
In has been desired to employ adhesion promoters in printing inks to promote the adhesion of the ink to a plastic substrate but hitherto the available adhesion promoters have tended to discolor the ink and in certain cases to produce an ink containing a somewhat objectionable odor. A new printing ink has been developed which is based on a polymeric binder, a solvent therefor and an adhesion promoting agent which is the reaction product of a titanium orthoester and either a monoalkyl phosphate or a dialkyl phosphate or a mixture thereof in such proportions that the molar ratio of titanium to phosphate expressed as Ti:P is from 4:1 to 1:2.
