Manufacturing method of the optical diffraction structure transfer copies of using replication version and method of manufacturing the replica version and duplicate version of the optical diffraction structure for shaping

摘要

PROBLEM TO BE SOLVED: To provide a duplicating impression capable of making a satisfied mold releasability sure by adding a large amount of a mold releasing agent to a resin as a raw material of an optical diffraction structure layer and also able to suppress separation of the mold releasing agent from the duplicating impression.;SOLUTION: An ultraviolet ray curable resin 3A loaded with a reactive silicone made by modifying a polyether modified silicone by acrylic modification as a mold releasing agent is interposed between an original impression 4 having the optical diffraction structure and a substrate 2 of the duplicate impression 1 where the optical diffraction structure is to be copied. The silicone and the ultraviolet ray curable resin 3A are cross-linking bonded under curing the ultraviolet ray curable resin 3A by irradiating the ultraviolet ray curable resin 3A with an ultraviolet ray UV.;COPYRIGHT: (C)2007,JPO&INPIT
