(57) Abstract: An object of the present invention is to provide an organopolysiloxane excellent in chemical durability such as water resistance, boiling water resistance and the like from a silicone oligomer solution obtained by hydrolyzing and polycondensing an alkoxysilane. Provided is a coating composition capable of forming a coating film. The average structural unit R 1 n SiO x / 2 (OH) y (OR 2 ) z (wherein, R 1 has 1 to 1 carbon atoms) 3 alkyl groups, vinyl groups or phenyl groups, all of which may be the same or different, R 2 is an alkyl group of 1 to 3 carbon atoms, which may be all the same or different, 0.8 ≦ n ≦ 1.7, 2 <x <3.2, and y> 0, z> 0, and y + z = 4-nx. ) A solution containing a silicone oligomer having (B) A coating composition comprising a buffered latent acid catalyst as a component. |
