Title:
PROCESS FOR PRODUCING OPTICAL MEMBER, AND ULTRAVIOLET-CURABLE RESIN COMPOSITION FOR USE IN SAME
Document Type and Number:
WIPO Patent Application WO/2015/199156
Kind Code:
A1
Abstract:
A process for producing an optical member which includes at least two optical substrates laminated to each other, the process comprising the following steps 1 to 3 and using a resin composition in which the 25°C storage modulus of a resin layer irradiated with ultraviolet rays in the following step 3 is 1.5-10 times that of the resin layer irradiated with ultraviolet rays in the following step 1 and which, after irradiated with ultraviolet rays in the following step 1, has a 25°C storage modulus of 1×102-1×104 Pa: [step 1] a step in which an ultraviolet-curable resin composition comprising a (meth)acrylate (A) and a photopolymerization initiator (B) is applied to at least one optical substrate to form a coating layer and the coating layer is irradiated with ultraviolet rays, thereby obtaining an optical substrate having a cured object layer comprising a cured portion of the coating layer which is present on the optical-substrate side and an uncured portion which is present on the reverse side from the optical-substrate side; [step 2] a step in which the uncured portion of the optical substrate obtained in step 1 is laminated to another optical substrate or to the uncured portion of another optical substrate obtained in step 1; and [step 3] a step in which the uncured-portion-containing cured object layer of the optical substrate laminated in step 2 is irradiated with ultraviolet rays through the other optical substrate, thereby curing the cured object layer.
