ABSTRACT The invention relates to an accelerated photoiniferter polymerization method which involves the addition of a polymerization accelerating amount of a at least one metal compound accelerator during the photoiniferter polymerization process. Preferably, the metal compound or compounds used are represented by the general formula MxLz wherein M is a cation having a valency of z of a metal which is selected from the group consisting of tin, zinc, cobalt, titanium, palladium, and lead; x is an integer of at least 1; L is an anion having a valency of x which is selected from the group consisting of C1-20 alkyl, -aryl, - OR, -O-?-R, NO3-, SO4?, and PO4-3; R is selected from the group consisting C1-20 alkyl and aryl; and z is an integer of at least 1. Most preferably, the metal compound is selected from the group consisting of stannous 2-ethylhexanoate, zinc 2-ethylhexanoate and mixtures thereof.
