<p>PROBLEM TO BE SOLVED: To obtain a curable composition exhibiting adequate hydrosilylating curability even with high polymerization degree of the siloxane-grafted chain, and forming a peelable cured film after cured, by including a specific polymer, a specific compound, and a specific catalyst. SOLUTION: This curable composition is obtained by including (A) a siloxane- graft-type vinyl polymer where siloxane chains of formula I and formula II [R<1> is a bivalent organic group; R<2> is a monovalent hydrocarbon group free from aliphatic unsaturated bond; R<3> is a monovalent hydrocarbon group; Y is an aliphatic unsaturated bond-contg. monovalent organic group; (a) is 0 or 1; (m) is 0-20; (n) is >= 1; (m+n)>(m); (p) is 1-3] are graft-bound to the side chain, (B) an organosilicon compound containing two or more hydrogen atoms bound to a silicon atom in one molecule and having the molar ratio of such hydrogen atoms to the aliphatic unsaturated bonds in the component A, and (C) a hydrosilylation catalyst.</p> |
