Printing ink system for printing polyamide-based food casings, printed food casings and methods of making same

摘要

Disclosed is a printed with a radically curable ink one-layer or multi-layer food casing based on (co) polyamide or with an outer layer based on (co) polyamide, which is characterized in that the ink on a layer of a free-radically curing Base color is printed, which contains in one and the same molecule at least one group which can form a bond with the (co) polyamide surface, in particular an isocyanate group, and at least one ethylenically unsaturated group which can undergo a free-radically initiated polyaddition reaction, in particular a (meth) acrylate group. The print adheres firmly to the cover and is resistant to abrasion and scratching, even without additional topcoat.
