<p><P>PROBLEM TO BE SOLVED: To provide a resin substrate with a coated film maintaining properties of the resin such as transparency and fracture resistance over a long time by excellent weatherability. <P>SOLUTION: In the resin substrate with the coated film, the coated film including an acrylic polymer with an acid number of 1 mg-KOH/g or less, a glass transition point of 60-150°C, and a mass-average molecular weight of 90,000-1,000,000, and an ultraviolet-absorbing component selected from a polymer and an ultraviolet-absorbing agent having an ultraviolet-absorbing group having an absorption coefficient of 3.5-100 g/(mg cm) as average values in a wavelength region of 350-380 nm, is formed on at least one of surfaces of the substrate comprising resin including an aromatic ring. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
