Abstract
UV hardenable lacquer, in particular for molded polycarbonate (PC) bodies, comprising: PA1 (A) 5 to 60%, referring to the total weight of 100% of the entire mixture, of an aliphatic polyurethane acrylate, preferably 5 to 20% of a hexa-functional PU acrylate; PA1 (B) 30 to 45%, referring to the total weight of 100% of the entire mixture, of a cross-linkable, polyfunctional acrylate having less than 20 C atoms in the molecule; PA1 (C) 0.01 to 3%, referring to the total weight of 100% of the entire mixture, of a cross-linkable polyfunctional silicon acrylate; PA1 (D) if required, between 1 and 5%, referring to the total weight of 100% of the entire mixture, of a monofunctional, ethylenically unsaturated compound such as N-vinyl pyrrolidone; PA1 (E) 0 to 70% referring to the total weight of 100% of the entire mixture, of organic solvents; PA1 (F) photo initiators; and PA1 (G) light protector.
