A curable composition which comprises the following twoncomponents: (I) a vinyl polymer having at least onencrosslinkable silyl group represented by the general formulan(1) given below, and (II) an epoxy resin or a polyether polymernhaving at least one crosslinkable silyl group;n -[Si(R 1 ) 2-b (Y) b O] m -Si(R 2 ) 3-a (Y) a n{wherein R 1 and R 2 each represents an alkyl group containing 1nto 20 carbon atoms, an aryl group containing 6 to 20 carbon atoms,nan aralkyl group containing 7 to 20 carbon atoms, or antriorganosiloxy group represented by the formula (R') 3 SiO- (innwhich R' represents a monovalent hydrocarbon group containingn1 to 20 carbon atoms and the three R's may be the same orndifferent) and, when there are two or more R 1 or R 2 groups, theynmay be the same or different; Y represents a hydroxy group orna hydrolyzable group and, when there are two or more Y groups,nthey may be the same or different; a represents 0, 1, 2 or 3;nb represents 0, 1 or 2; and m represents an integer of 0 to 19;nwith the condition that a, b and m satisfy the relation a+mbn≧1 }. |
