PURPOSE:To obtain an inexpensive composition having sufficient photosetting rate and excellent release characteristics and ink repulsion by adding a curing catalyst to a reaction product of a specific silicone compound and an organopolysiloxane. CONSTITUTION:(C) A curing catalyst is added to a reaction product of (A) a silicone compound shown by formula I (R is 1-10C alkyl, etc.; X and Y are H, halogen, amino, etc.; Z is H, halogen, 1-10C alkyl, etc.; (n) is 0 or 1) and (B) an organopolysiloxane containing a terminal shown by formula II (R2 and R3 are 1-10C alkyl, alkenyl or 6-10C aryl; (m) is >=2 integer) with silanol structure. The silicone compound of the component A is preferably a compound wherein XY is acetoxy in the formula I. The component B contains preferably 60% methyl group. The component C is preferably dimethyltin diacetate. |
