Title: Preparation method of copolymerizable photoinitiators

Abstract: An intermediate for preparing (meth)acrylated photoinitiators according to Formula (I): ##STR00001## wherein: R1 is selected from the group consisting of hydrogen and a methyl group; A represents a group including at least one photoinitiating moiety; L represents a n+o-valent linking group including at least one carbon atom; n and o each independently represent an integer from 1 to 4; p is equal to 0 or 1; X represents a group selected from the group consisting of Cl, Br, I, and R.sup.2SO.sub.3; and R.sup.2 represents an optionally substituted group selected from the group consisting of an alkyl group, an alkenyl group, an alkynyl group, an alkaryl group, an aralkyl group, an aryl group and a heteroaryl group. Also, a method for the preparation of (meth)acrylated photoinitiators by .beta.-elimination of HX from the intermediate according to Formula (I).
