Abstract
Photopolymerizable compositions containing PA0 (1) a polymer having a plurality of salt-forming groups, PA0 (2) an ethylenically unsaturated compound having at least one complementary salt-forming group, PA0 (3) an ethylenically unsaturated diester polyhydroxy polyether of the formula ##STR1## where R is H or CH.sub.3 ; R.sup.1 is H or an alkyl group of 1-4 carbon atoms; n is 1-15; p is 0 or 1; and when p is 1, R.sup.2 is H or CH.sub.3, and R.sup.3 is H, CH.sub.3 or C.sub.2 H.sub.5 ; and PA0 (4) a radiation-sensitive, free-radical generating system provide photopolymerizable elements which have outstanding photospeeds and are relatively insensitive to oxygen.
