[PROBLEMS] To provide a screen printing plate capable of producing a printed circuit board having a line width of about 10 μm and a high aspect ratio, a method for producing the same, and a photosensitive resin composition used for producing the screen printing plate. provide. (1) A methacrylate copolymer containing a structural unit represented by formula (I); (2) a photo-radical initiator, (3) a photo-acid generator that generates an acid upon irradiation with light having a wavelength range different from at least light that generates a radical in the photo-radical initiator, and (4) a crosslinking reaction by the radical. A photosensitive resin composition comprising a crosslinking agent. [Selection figure] None |
