Abstract
Official abstract text for this publication.
The present invention provides a coating composition capable of forming a coating film that is applicable to a variety of industrial products, particularly automobile exterior panels, while exhibiting a high lightness and a low ultraviolet transmittance at a wavelength of 420 to 480 nm. The present invention relates to a coating composition comprising a chloride process titanium oxide pigment, a yellow iron oxide pigment, a carbon black pigment having a primary average particle size of 15 to 80 nm, and a resin composition, which is a vehicle-forming component, wherein when the coating composition is applied to give a cured film having a thickness of 25 μm, the resulting cured coating film has an average light transmittance within the range of 0.1 to 1.0% at a wavelength of 420 nm to 480 nm., and the invention also relates to a method for forming a multilayer coating film, comprising forming a color base coating film on a coating film obtained by applying the coating composition.
First claim
Opening claim text (preview).
1 . A coating composition comprising a chloride process titanium oxide pigment, a yellow iron oxide pigment, a carbon black pigment having a primary average particle size of 15 to 80 nm, and a resin composition, which is a vehicle-forming component, wherein when the coating composition is applied to give a cured film having a thickness of 25 μm, the resulting cured coating film has an average light transmittance within the range of 0.1 to 1.0% at a wavelength of 420 nm to 480 nm. 2 . The coating composition according to claim 1 , wherein when the coating composition is applied to give a cured film having a thickness of 25 μm, the resulting cured coating film has an L*value within the range of 80 to 95, an a*value within the range of −2.0 to 2.0, and a b*value within the range of 0.1 to 5.0 in the L*a*b* color space. 3 . A method for forming a multilayer coating film, the method comprising forming a color base coating film on a coating film obtained by applying the coating composition according to claim 1 to a substrate. 4 . The method for forming a multilayer coating film according to claim 3 , wherein the color base coating film comprises a coating film obtained by applying a metallic coating composition containing a flake-effect pigment; and a coating film obtained by applying a top clear coating composition. 5 . A method for forming a multilayer coating film, the method comprising forming a color base coating film on a coating film obtained by applying the coating composition according to claim 2 to a substrate.
