Title:
METHOD FOR FORMING MULTILAYER COATING FILM
Document Type and Number:
WIPO Patent Application WO/2016/121238
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method with which it is possible to form a multilayer coating film via the three-coats-one-bake system, in which an aqueous first pigmented coating material, an aqueous second pigmented coating material, and a clear coating material are sequentially coated on a coat-receiving object, and the resulting three-layer multilayer coating film is simultaneously heat-cured, such that the multilayer coating film has excellent smoothness and clarity and exhibits excellent coating film performance including water resistance and, when the multilayer coating film has a lustrous coating film layer, a finished appearance that does not have a metallic feel or metallic unevenness. Provided is a method for forming a multilayer coating film via the three-coats-one-bake system, in which an aqueous first pigmented coating material, an aqueous second pigmented coating material, and a clear coating material are sequentially coated on a coat-receiving object, and the resulting 3-layer multilayer coating film is simultaneously heat-cured, said method characterized in that the aqueous second pigmented coating material contains (A) a film-forming resin and (B) a phosphate compound represented by a predetermined general formula.
