<p>PCT No. PCT/EP96/05159 Sec. 371 Date Jun. 19, 1998 Sec. 102(e) Date Jun. 19, 1998 PCT Filed Nov. 22, 1996 PCT Pub. No. WO97/22420 PCT Pub. Date Jun. 26, 1997To form paint films of outstanding acid resistance, finished appearance, water resistance, adhesion and bending resistance by coating a base finishing coat and top finishing coat wet-on-wet. A method for forming a paint film by a method for forming a thermosetting paint film in which a solvent-based thermosetting base finishing coat is painted onto the surface of an object to be painted, a thermosetting top finishing coat is painted on top of this wet-on-wet, and the paint films are hardened at the same time, in which the aforementioned top finishing coat which contains as a primary resin a copolymer which is a copolymer of a vinyl monomer which has a ring structure and other vinyl monomers in which the proportion of vinyl monomer having a ring structure in the total quantity of monomers is 20-50 wt %, and the proportion of other vinyl monomer(s) is 80-50 wt %, and which has a glass transition temperature of 0-60 DEG C., a solubility parameter of 9.0-11.0 and a weight-average molecular weight of 4000-30,000.</p> |
