ABSTRACT:
A method for forming a coated film comprising the steps of sequentially applying an intermediate coating material, a base coating material and a clear coating material on a substrate on which an electrodeposition coated film has been formed; and simultaneously curing the applied three layers by baking, wherein the intermediate coating material comprises: (a) 40 to 56% by weight of an urethane modified polyester resin, the urethane modified polyester resin being obtainable by polyaddition of: a hydroxyl group containing polyester resin which is obtainable by polycondensation of an acid ingredient including not less than 80% by mole of isophthalic acid with a polyhydric alcohol ingredient, with an aliphatic diisocyanate compound; (b) 10 to 30% by weight of a melamine resin; (c) 15 to 30% by weight of a blocked isocyanate compound; (d) 4 to 15% by weight of a nonaqueous dispersion resin having core-shell structure; and (e) 0.4 to 2 parts by weight of a flake-like pigment. The resulting layered coated film is superior in aesthetic appearance and chipping resistance even formed in the three-coating and one-baking method.
