Abstract: A method for forming a glittering coating film in which after a glittering base coating film is formed on a substrate to be coated by applying thereto a glittering base coating material containing a colloid particle liquid containing noble metal or copper colloid particles, the glittering base coating film is heated or set, and then a clear coating film is formed. By the method, a glittering coating film is provided which has weathering resistance and high gloss, and develops a metal feeling or a coloring metal feeling giving rise to a less feeling of metal particles than by the plating-tone coating film, and superior in design property.

Abstract: Disclosed is a method for forming a glittering coating film in which after a glittering base coating film is formed on a substrate to be coated by applying thereto a glittering base coating material containing a colloid particle liquid containing noble metal or copper colloid particles, said glittering base coating film is heated or set, and then a clear coating film is formed by executing any one of the following processes (A) to (F). By the method, a glittering coating film is provided which has weathering resistance and high gloss, and develops a metal feeling or a coloring metal feeling giving rise to a less feeling of metal particles than by the plating-tone coating film, and superior in design property.

Abstract: The present invention provides a paint composition which contains a non-glorious color pigment and a scaly glorious color pigment, wherein both the contained non-glorious color pigment and scaly glorious color pigment are selected so as not to be similar colors.

Abstract: A coating composition comprising metallic flake pigments having an average thickness of 0.5 to 1.5.mu. and an average diameter of 10 to 45.mu., selected from the group consisting of aluminium flakes, bronze flakes, tin flakes, gold flakes, silver flakes, titanium flakes, stainless steel flakes, nickel flakes, copper flakes, their alloyed metal flakes, plastic-coated metal flakes and flake phthalocyanine blue, and ultra-fine particles having an average particle diameter of 5 to 400 m.mu., the weight ratio of said flake pigments to ultra-fine particles being 1:0.05 to 1:12, uniformly dispersed in a thermosetting resin vehicle. The present coating composition is useful as a top coat and especially as a base coat composition for 2-coat-1-bake coating system for automobile body, appliance or the like, resulting an excellent metallic effect and decorative interference color effect.
