A radiation-curable composition

摘要

A radiation-curable composition for use as a base coat in printing on plastic substrates such as polycarbonate. The radiation-curable composition comprises: (i) an ethylenically unsaturated monomer that is capable of being photopolymerized; (ii) a photoinitiator that is capable of initiating the polymerization of the ethylenically unsaturated monomer (i) when irradiated with ultra-voilet light; (iii) an inorganic transfer agent; (iv) an adhesion promoter; and (v) optionally, a pigment. The base coat is suitable for use in printing plastics substrates using electrostatic offset printing.
