Printing ink and printing lacquer with excellent adhesion, especially in packaging of food products

摘要

Printing ink or printing lacquer, especially for stamping food packaging, containing: a) at least one binder resin, b) at least one solvent and c) at least one adhesion promoter, containing the promoter of the adhesion a copolymer which is composed of i) at least one C1-5 alkyl titanate monomer and / or a C1-5 alkyl zirconate monomer, the linear or branched alkyl moieties being, and ii) at least one monomer of C4-10 mono-alkyl phosphate and / or at least one di-C4-10 alkyl phosphate monomer, the mono- and di-C4-10 alkyl phosphate monomers comprising both linear and also C4-10 alkyl moieties branched, the adhesion promoter formulation containing less than 0.25% by weight of tributyl phosphate, and the molar ratio of branched C4-10 alkyl moieties relative to the sum of linear and branched C4-10 alkyl moieties to a value of 10 to 90% in the copolymer of l adhesion promoter.
