  • Publication number: 20240301234
    Abstract: An object of the present invention is to provide a powder component of which a coating film having excellent transparency can be formed, a resin composition for coating, and a coating film. A powder component of the present invention is a powder component containing a polyarylate containing a repeating unit represented by Formula (A-I) and a repeating unit represented by Formula (A-II), and a compound that is different from the polyarylate and that has a repeating unit represented by Formula (B), in which a value obtained by subtracting a measured value 1 from a measured value 2 is 2,000 ppm by mass or less. Measured value 1: a proportion of a mass of a compound represented by Formula (C) in the powder component with respect to a whole mass of the powder component. Measured value 2: a proportion of the mass of the compound represented by Formula (C) in a mixture obtained by mixing the powder component with diethylamine with respect to the whole mass of the powder component.
