Abstract
There are disclosed a high solids content resin composition excellent in solubility in an organic solvent, comprising an acrylic oligomer having a blocked hydroxyl group, a curing agent having a reactivity with a hydroxyl group and a dissociation or curing catalyst, and a high solids content type paint using the resin composition. There are also disclosed a coating process and a baking process comprising coating and baking the resin composition or the paint while rotating a material to be coated at an appropriate speed. The resin composition and the paint of the present invention have substantially no sagging and solvent popping. Further, the thus obtained paint film have improved smoothness, solvent resistance, weather resistance and resistance to scratching.
