<p><P>PROBLEM TO BE SOLVED: To provide a laminated coating film structure including upper coating films 3, 4 laid over a lower coating film 2 formed by an electrodeposition coating method or the like, made to have enhanced photodegradation resistance without forming an intermediate coating film. <P>SOLUTION: The upper coating films 3, 4 of the laminated coating film structure are each made to have an average light transmittance in the wavelength range of not lower than 300 nm and not higher than 390 nm, of lower than 0.5% and an average light transmittance in the wavelength range of not lower than 390 nm and not higher than 450 nm, of not higher than 6.5%, or made to have an average light transmittance in the wavelength range of not lower than 300 nm and not higher than 390 nm, of not lower than 0.5% and an average light transmittance in the wavelength range of not lower than 390 nm and not higher than 450 nm, of not higher than 4.5%. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
