ABSTRACT:
The present invention relates a topcoating composition and a film-forming process by use of the topcoating composition, which are capable of forming a coated film having good weather resistance and good stain resistance. The present invention provides a topcoating composition prepared by incorporating a specified organosilicate and/or its condensate into a specified organic coating composition, a film formed from said topcoating composition being such that a surface of the film, which has been subjected to an acid treatment, shows a contact angle to water of 70.degree. or less; and a film-forming process which comprises coating said topcoating composition onto a substrate to form a film, followed by treating the surface of the film with an acid.
