  • Publication number: 20230323134
    Abstract: A photosensitive resin composition and a cured product are provided. The photosensitive resin composition includes an alkali-soluble resin (A), polymerizable monomer (B), an antioxidant (C), a photoinitiator (D) and a solvent (E). The weight average molecular weight of the alkali-soluble resin (A) is 5,000 to 40,000. The polymerizable monomer (B) includes an ethylenically unsaturated monomer (B1), an epoxy monomer (B2) or the combination thereof. The alkali-soluble resin (A) includes at least one of a structural unit represented by following Formula (A-1) to Formula (A-4). In Formula (A-1) to Formula (A-4), the definition of R1 to R3, m, n and * are the same as defined in the detailed description.
