A photosensitive resin laminate that has excellent adhesion and development cohesiveness, reduces rib top defects, and can process fine patterns on a substrate to be processed as a mask material for sandblasting with high yield, and the same A sandblast surface processing method is provided. A photosensitive resin composition comprising a specific polyurethane prepolymer, a photopolymerization initiator, and a specific ethylenically unsaturated addition polymerizable monomer, or a photosensitive resin laminate obtained by laminating the photosensitive resin composition on a support. Used to perform sandblasting surface processing. [Selection figure] None |
