Title:
EPOXY RESIN, EPOXY RESIN COMPOSITION CONTAINING THE SAME AND CURED ARTICLE THEREOF
Document Type and Number:
Japanese Patent JP2017186478
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an epoxy resin composition containing a silicone modified epoxy resin having a glycidyl ester group, which is extremely useful as a material requiring high transparency and high light extraction efficiency, especially a resin for optical semiconductor as the epoxy resin composition provides LED having high transparency, high light extraction efficiency and high luminous flux maintenance factor.SOLUTION: There is provided a silicone modified epoxy resin (A) containing 2 or more epoxy groups in a molecule, where 20 mol% or more of the epoxy groups is a glycidyl ester structure, and an epoxy resin composition containing the same.SELECTED DRAWING: Figure 1
