摘要： A photocurable composition includes a photopolymerizable component and a photopolymerization initiator. When a test piece with a length of 39 mm, a width of 8 mm, and a thickness of 4 mm, is produced by photofabrication under conditions in which the photocurable composition is irradiated with visible light having a wavelength of 405 nm at an irradiation dose of 12 mJ/cm2 to form a cured layer with a thickness of 100 µm, the cured layer is stacked in a thickness direction thereof to form a rectangular fabrication product with a length of 39 mm, a width of 8 mm, and a thickness of 4 mm, and the fabrication product is irradiated with ultraviolet rays having a wavelength of 365 nm at an irradiation dose of 10 J/cm2 to produce the test piece, a total fracture work of the test piece measured in compliance with ISO20795-1:2008 is 1100 J/m2 or more.

摘要： The purpose of the present disclosure is to provide a pellicle that has an adhesive layer having good flatness, and a method for producing the pellicle with good reproducibility. Said purpose is achieved by a pellicle having: a pellicle frame; a pellicle film provided so as to be stretched on one end surface of the pellicle frame; and an adhesive layer provided on the other end surface of the pellicle frame. The adhesive layer contains a cured product of a resin composition containing a curable polymer (A), and a curing agent (B1) and a curing agent (B2). The curing agent (B1) and the curing agent (B2) have different curing conditions.
