ULTRAVIOLET CURING TYPE EPOXY RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide an ultraviolet curing type epoxy resin composition which is the ultraviolet curing type useful in optical applications with extremely slight generation of vaporized gas, further useful as an ultraviolet curing type adhesive for optical part materials such as an array waveguide or a lens and for fixing optical parts without requiring a treatment at high temperatures and having transparency for optical signals. SOLUTION: The ultraviolet curing type epoxy resin composition comprises the following (A) and (B). (A) is an epoxy resin containing at least one of a straight-chain type aliphatic epoxy resin represented by general formula (1) and a straight-chain type fluorinated epoxy resin represented by general formula (2) with the content of the epoxy resin set at 40-90 wt.% based on the whole epoxy resin component. (B) is a photopolymerization initiator. COPYRIGHT: (C)2005,JPO&NCIPI
