Photocurable resin composition imprints, its manufacturing method and structure

2013 
Providing the issue photocurable resin composition curing shrinkage of the optical imprint is suppressed. The surface hardness is high, to provide a photocurable resin composition which can be structures can cause yellowing is suppressed even under irradiation, such as ultraviolet rays is prepared by the photo-imprinting. [SOLUTION] imprints photocurable resin composition of the present invention, (meth) A photocurable resin composition comprising an acrylic monomer (A) and a photoinitiator (B), the photoinitiator (B) is a combination of alkyl phenone photoinitiator (B1) and acylphosphine oxide-based photoinitiator (B2), the alkyl phenone photoinitiator (B1) and the acylphosphine oxide-based photoinitiator agent (B2) mixing weight ratio of (B1: B2) is 1: 99 to 90: characterized in that it is within 10 range.
