Abstract
Process for the production of molded bodies, impregnations, coatings and the like from preparations capable of being cured by ultraviolet irradiation, such as molding, impregnation and coating compositions based on conventional stabilized mixtures of unsaturated polyester resins, of monomeric compounds capable of being polymerized together with the chain, and of photoinitiators, which eventually additionally contain polymerization initiators and/or metallic accelerators and/or paraffin or wax or waxy substances, characterized in that as a photoinitiator employs a global combination consisting of: (a) 0.1 to 4% by weight of benzoinethers and (b) a subcombination of at least two different trivalent phosphorous compounds, consisting of: (b') 0.1 to 20 wt% organic esters of phosphorous acid with the general formula **(See formula)** where R1, R2 and R3 may be the same or different and represent aliphatic, cycloaliphatic, aromatic, araliphatic or heterocyclic radicals - but one of the radicals R1, R2 or R3 must always be an aromatic radical -, and (b'') 0 0.05 to 2% by weight of organic phosphine derivatives with the general formula **(See formula)** where R1, R2 and R3 may be the same or different and represent aliphatic, cycloaliphatic, aromatic, araliphatic or heterocyclic radicals - but one of the radicals R1, R2 or R3 must always be an aromatic radical and the quoted weight percentages refer to the weight Total resin of unsaturated polyesters and monomers that can be polymerized together with the chain.
