Beschreibung
Zusammenfassung:	Provided is a UV-curable silicone composition containing:(A) an organopolysiloxane having, in one molecule, two groups represented by formula (1)(R1 is a monovalent hydrocarbon group, R2 is an oxygen atom or an alkylene group, R3 is an acryloyloxyalkyl group, etc., p represents a number satisfying 0 ≤ p ≤ 10, and a represents a number satisfying 1 ≤ a ≤ 3.);(B) an organopolysiloxane resin which comprises (a) a unit represented by formula (2)(R1 to R3, a and p are the same as above),(b) a R43SiO1/2 unit (R4 represents a monovalent hydrocarbon group), and (c) a SiO4/2 unit, and in which a molar ratio of the sum of the unit (a) and the unit (b) and the unit (c) is 0.6 to 1.2 : 1;(C) a photopolymerization initiator; and(D) an organic peroxide,wherein the UV-curable silicone composition has a viscosity applicable to a stereolithography such as a laser process, can be shaped even with a small amount of UV irradiation, and forms a cured product exhibiting excellent rubber physical properties.
