FIELD: chemistry.

SUBSTANCE: described is an activator of adhesion of ink to a substrate, containing a product of reaction of (a) a polymer solution or synthetic resin, (b) sulphonic acid or derivative thereof and (c) a metal compound selected from a group consisting of a metal halide, metal alkoxide, metal halide-alkoxide or a condensed metal alkoxide, where the metal is titanium or zirconium. The amount of sulphonic acid or sulphonic acid salt (b) and metal compound (c) corresponds to molar ratio of SO₃X, where X is a H atom or a base residue, to Ti and Zr atoms ranging from 0.25:1 to 2:1. The invention also describes printing ink containing said adhesion activator.

EFFECT: reduced yellowing and smell of ink compared to ink which contains titanium acetyl acetonate as an adhesion activator while preserving effectiveness of the adhesion activator.
