PROBLEM TO BE SOLVED: To obtain the subject mixture useful for producing a coating film capable of exhibiting excellent casting property, controllability of peeling force, hardenability, supporter adhesive property, etc., and rejecting a tacky material by including a mixture of a specific organic silicone polymer having (meth)acryloyloxy groups. SOLUTION: The mixture comprises (A) a linear organopolysiloxane having (meth) acryloyloxy groups such as a compound of formula I [R is a 1-18C (substituted) hydrocarbon monofunctional group, etc., not containing an aliphatic carbon-carbon-multiple bond at a terminal position; R1 is a group of formula II R2 is H or methyl; R3 and R4 are each a 1-6C alkylene; (z) is 1-10} (m) and (n) are each 0-200; (x) is 0 or 1; at least a piece of R1 is contained in a molecule], (B) a copolymer having (meth) acryloyloxy groups such as a copolymer having a structural unit of the formula; M0Q (M0 is a unit of the formula: R3SiO1/2; Q is SiO2 unit) or a structural unit of the formula: M1Q (M1 is a unit of the formula; R1R2SiO1/2), (C) a photopolymerization initiator, and arbitrarily (D) an organic (oligo)(meth)acrylate.
