PURPOSE:A resin composition improved in flexibility, solvent resistance and bearing rusting resistance, prepared by mixing a polyester resin comprising an aliphatic dibasic acid and an aliphatic glycol with a caprolactone-modified epoxy resin and an aminoaldehyde resin. CONSTITUTION:A resin composition containing a polyester resin (A) containing an aliphatic dibasic acid and 10-40wt% aliphatic glycol, a caprolactone-modified epoxy resin (B) of the formula (wherein m is 1-6 and n is 1-9) and an aminoaldehyde resin (c) at such a ratio that the caprolactone-modified epoxy resin is used in an amount of 5-20wt%, based on the polyester resin, and the aminoaldehyde resin is used in an amount of 5-25wt%, based on the total amount of the resins [(A)+(B)+(C)]. Examples of the aminoaldehyde resin (C) used include melamine resins, urea resins and benzoguanamine resins. |
