Abstract

PURPOSE:To improve hardenability and air-drying property, and to prevent a malodor and air pollution by conducting varnish treatment with a resin composition containing specified resin. CONSTITUTION:A 5-30pt.wt. maleic anhydride is addition-reacted with 100pt.wt. drying or semidrying animal and vegetable oil, and maleic oxidized oil is obtained. The varnish treatment is conducted with the resin composition containing the resin acquired by addition-reacting hydroxyalkylacrylate or hydroxyalkylmethacrylate shown in a general formula of 0.5mol or more with 1mol acid anhydride group of the maleic oxidized oil.
