摘要：
Photopolymerizable mixtures of (a) one or more block copolymers, (b) one or more photopolymerizable, ethylenically unsaturated, low molecular weight compounds and (c) a photopolymerization initiator, with or without (d) other additives, contain as component (a) block copolymers which are composed solely of elastomeric polymer blocks, and contain two or more elastomeric polymer blocks having a glass transition temperature of from -20.degree. C. to +15.degree. C., linked by one or more elastomeric polymer blocks having a glass transition temperature of below -20.degree. C.
