    • A photoactive compound of general formula (I) that is the reaction of an alkenyl azalactone compound and a nucleophilic aromatic ketone is described. Mer units derived from this compound can be used, for example, to crosslink via a hydrogen abstracting mechanism acrylic polymers in which they are incorporated. In said formula (I) wherein R is H or a C1 to C3 alkyl group; R and R are independently H, an alkyl group having 1 to 14 carbon atoms, a cycloalkyl group having 3 to 14 carbon atoms, an aryl group having 5 to 12 ring atoms, an arenyl group having 6 to 26 carbon atoms and 0 to 3 S, N, and nonperoxidic O heteroatoms, or R and R taken together with the carbon to which they are attached form a carbocyclic ring containing 4 to 12 ring atoms; n is 0 or 1; A is XCR R , [X(CH2CHR )]m ou X-[(CH2CHR Y)]m where X est O, S, NH, or NR ; Y is O, C(O)O, OC(O)NH, OC(O)O, or NHC(O)O; R and R are independently H, a C1 to C6 alkyl group, or an aryl group; and m is 0 or 1; and Z is a moiety derived from an acetophenone, benzophenone, anthraquinone, 9-fluorenone, anthrone, xanthone, thioxanthone, acridone, dibenzosuberone, benzil, or chromone.
