Abstract: THE INVENTION RELATES TO MOULDING AND COATING COMPOSITIONS WHICH CAN BE SET BY U.V. IRRADIATION COMPRISING MIXTURES OF UNSATURATED POLYESTERS AND COPOLYMERISABLE MONOMERIC COMPOUNDS, SENSITIZED BY AN EFFECTIVE AMOUNT OF BENZOIN ETHERS OF PRIMARY ALCOHOLS AND STABILIZED BY AN EFFECTIVE AMOUNT OF COPPER COMPOUNDS. THE COMPOSITIONS ARE DISTINGUISHED BY A HIGH STORAGE STABILITY IN THE DARK AND A HIGH REACTIVITY UNDER U.V. RADIATION, WHILE THE CURING VELOCITY IS ADDITIONALLY INCREASED BY INFRARED RAYS.
