PURPOSE:To manufacture a releasant composition for forming a silicone film excellent in durability and release properties. CONSTITUTION:A releasant composition is composed of the followings (a)-(c). That is, (a) 0.1-50wt.% silicone resin having the mol ratio of 95/5-50/5 for an R<1>SiO3/2 structural unit and an R<1>2SiO2/2 structural unit (R<1> in the formula is saturated or unsaturated monovalent hydrocarbon of 1-18C.), (b) 0.01-10wt.% linear organopolysiloxane containing phenyl represented by the formula (R<2> in the formula is hydroxyl or saturated or unsaturated monovalent hydrocarbon of 1-18C, and R<3> is hydroxyl or saturated or unsaturated monovalent hydrocarbon of 1-18C, and both of them contain 0.01-20mol% phenyl, average value of (m) is 40-20,000.) and (c) 99.89-50wt.% organic solvent to be able to dissolve (a) and (b) components. |
