PURPOSE:To obtain a heat-resistant coating material with excellent adhesive properties without performing various surface treatment for improving adhesive properties by incorporating an alkoxy-modified amino resin and benzotriazole in a polyamideimide resin. CONSTITUTION:A heat-resistant coating material is obtd. by incorporating 1-40 pts.wt. alkoxy-modified amino resin (a compd. prepd. by methoxylation or butoxylation of a reaction product of urea, melamine, benzoguanamine, etc., with formaldehyde) and 0.01-0.7 pts.wt. benzotriazole or a deriv. thereof (e.g. benzotriazole or 1-oxygenzotriaxole) in 100 pts.wt. polyamideimide resin (a reaction product of an arom. diisocyanate of an arom. diamine with an arom. tribasic acid anhydride). This coating material provides excellent adhesive properties to a copper sheet and it is possible to obtain a coated copper sheet with high adhesive properties without performing various surface treatment for improving adhesive properties. |
