Title:
ULTRAVIOLET CURABLE RESIN COMPOSITION AND METHOD FOR SEPARATING CURED PRODUCT OF SAME
Document Type and Number:
WIPO Patent Application WO/2013/077080
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: an ultraviolet curable resin composition which enables recovery of an optical base from an optical member, which is bonded using an ultraviolet curable resin, with less damage to the optical base and with high productivity; and a method for separating a cured product of the ultraviolet curable resin composition. The ultraviolet curable resin composition is used in a method for separating a layer that is present on the surface of an optical base and obtained by curing an ultraviolet curable resin composition, said method comprising (step 1) to (step 3) described below. The ultraviolet curable resin composition contains (A) a methacrylate and (B) a photopolymerization initiator.
(Step 1) A step of bringing a base for separation into contact with a layer that is obtained by curing an ultraviolet curable resin composition.
(Step 2) A step of having the layer that is obtained by curing an ultraviolet curable resin composition adhere to the base for separation.
(Step 3) A step of separating an optical base and the layer that is obtained by curing an ultraviolet curable resin composition from each other by separating the layer from the optical base by having the layer adhere to the surface of the base for separation, thereby collecting the layer thereon.
