Adhesion inducer to improve the adhesion of a printing ink or a printing lacquer on a substrate

摘要

Adhesion inducer, in particular to improve the adhesion of a printing ink or of a printing lacquer to a substrate, in particular to a food packaging, wherein the adhesion inducer contains a copolymer consisting of i) at least one C1-5 alkyl titanate monomer and / or one C1-5 alkyl zirconate monomer, the radicals being linear or branched alkyl, ii) at least one C4-10 alkyl monophosphate monomer and iii) at least one monomer of C4-10 alkyl diphosphate, the monomers of mono- and di-phosphate of C4-10 alkyl radicals containing both linear and branched C4-10 alkyl, the molar ratio of branched C4-10 alkyl radicals, referred to to the sum of linear and branched C4-10 alkyl in the copolymer, from 10 to 90%.
