Abstract
A printing ink for printing slightly adhesive plastic bases, especially polyoxymethylenes and polypropylenes, comprises an ultraviolet-curing ink and an isocyanate compound added thereto. The isocyanate compound is added in an amount of 0.5 to 35 parts by weight per 100 parts by weight of the ultraviolet-curing ink. The invention relates also to printed matter on which given characters, figures, or/and patterns have been printed using such an ultraviolet-curing ink. The invention relates further to a printing method for giving such printed matter. The printing is preceded by a pretreatment selected from among corona discharge, shortwave ultraviolet radiation, and electron radiation.
