Abstract:
Disclosed is a coating composition and coating film forming method which can be used in various industrial products, particularly the outer panels of vehicles, and which can obtain a coating colour which has high chroma saturation in the highlight, and little change in subjective brightness from the face to the shade. The disclosed coating composition includes a coloured aluminium pigment and a titanium dioxide pigment, and when light is irradiated at a 45 degree angle on a coating film obtained by applying the coating composition, the ratio of subjective brightness L* which is obtained when the specular reflected light is received at an angle of 45 degrees to the subjective brightness L* obtained when the specular reflected light is received at an angle of 110 degrees is within the range of 1.00-1.50. The disclosed coating film forming method includes a step in which the coating composition is applied to a substrate, followed by the application of a clear coating material.
