  • Publication number: 20230312869
    Abstract: The object of the present invention is to provide a colored resin composition containing an aluminum phthalocyanine pigment capable of forming a colored coating film with no foreign matter (preferably a colored coating film with no foreign matter and good adhesion). The colored resin composition of the present invention contains a colorant, a compound represented by formula (DA), a resin, and a solvent, wherein the colorant contains an aluminum phthalocyanine pigment. [In formula (DA), Rd1 represents a hydrocarbon group having 1 to 12 carbon atoms and optionally having a substituent. When the hydrocarbon group has 2 to 12 carbon atoms and the hydrocarbon group has —CH2—, —CH2— may be substituted with —O—, —S—, or —CO—. Rd2 and Rd3 each independently represent a hydrogen atom or a hydrocarbon group having 1 to 12 carbon atoms and optionally having a substituent, or Rd2 and Rd3 are combined to form a ring together with —CO—NRd1—CO—.
