Zusammenfassung:	An ultraviolet radiation-curable epoxyfunctionalized silicone controlled release composition having increased release levels is provided, comprising: (A) an epoxyfunctional diorganopolysiloxane; (B) a catalytic amount of a photocatalyst or a combination of photocatalysts; and (C) from about 1% to about 30% by weight based on (A) of an epoxyfunctional siloxane resinous controlled release additive comprising monovalent siloxane and epoxyfunctional siloxane units and tetravalent SiO2 units. A release of at least 500 grams/2 inches is achieved by using from about 20% to about 30%, preferably from about 25% to about 30%, of component (C) and dispersing components (A)-(C) in (D) an amount of a hydrocarbon solvent sufficient to provide the composition with a solids content of about 20% and a solvent content of about 80%.
