<p>A primer composition usable for steel sheets and plastic sheets in vehicle bodies consists essentially of a component (A) consisting essentially of at least one resin having a glass transition temperature of not higher than -20 DEG C., preferably not lower than -75 DEG C., and an elongation at break of not less than 400%, preferably not greater than 900%, at 20 DEG C. and a component (B) consisting essentially of at least one crosslinking resin, the weight ratio as solid content of (A) to (B) being 70-99:30-1.</p> |
