Document Type and Number:
WIPO Patent Application WO/2015/125518
Kind Code:
A1
Abstract:
[Problem] Conventionally, it has been difficult to prevent the occurrence of bleeding out of a plasticizer, to reduce a ratio of shrinkage upon curing and to reduce a viscosity even when various acrylic resins are used. The present invention is an invention whereby it becomes possible to prevent the occurrence of bleeding out of a plasticizer, to reduce a ratio of shrinkage upon curing and to reduce a viscosity even when various acrylic resins are used, and the present invention is a photocurable composition which has a low ratio of shrinkage upon curing and is therefore suitable as a temporary fixing agent.
[Solution] A photocurable composition which contains components (A) to (D) mentioned below, wherein the total amount of the components (B) and (C) is 100 parts by mass or more relative to 100 parts by mass of the component (A), and a curing agent and/or a curing accelerator each capable of reacting with the component (B) is not contained: (A) a compound having an acrylic group; (B) an epoxy resin having a liquid form at 25ºC; (C) a (meth)acrylic polymer having a liquid form at 25ºC; and (D) a photoinitiator.
