PROBLEM TO BE SOLVED: To provide a radiation-curable composition for producing a tack-free coating having a large release force. SOLUTION: The composition has the following general formula (A): R 1 x R 3-x SiO (R 2 SiO) m (SiRR 1 O) n SiR 3-x R 1 x (I) and / or R 1 a R 3-a SiO (R 2 SiO) c in [R 2 Si-Y-SiR 2 O (R 2 SiO) c] d SiR 3-b R 1 b (II) [wherein, R in claim 1 Wherein R 1 is of the formula: Wherein R 2 , R 3 , R 4 , y, c, d, m, n and z represent those described in claim 1, and x, a And b represent those described in claim 1, with the proviso that in formula (II), the sum of a + b for each molecule is 1 or 2.] (B) (B1), (B2), (B3) and (B4) (B1 to B4 represent those described in claim 1), a (meth) acryloxy copolymer soluble in the component (A), (C) a photopolymerization initiator and optionally (D) an organic monomer. -, Di- or oligo (meth) acrylates or mixtures thereof. |
