Abstract
A curable composition, comprising a siloxane grafted vinyl polymer as its main component, reacts with an organic silicon compound having silicon-bonded hydrogen atoms in the presence of a hydrosilylation catalyst to form a peelable cured coating film. The siloxane grafted vinyl polymer has two unique grafted siloxane chains represented by the following general formulae (A) and (B): ##STR1## where R.sup.1 is a divalent organic group, R.sup.2 is a monovalent hydrocarbon group which is free of aliphatic bonds, R.sup.3 is a monovalent hydrocarbon group, Y is a monovalent organic group having unsaturated aliphatic bonds, a is 0 or 1, m is an integer between 0 and 20, n is an integer which is I or greater, and p is an integer of 1, 2 or 3.
