Abstract

A curable resin composition which comprises both an epoxy compound represented by general formula (I) and an energy -ray-sensitive cationic-polymerization initiator. In general formula (I), X, Y and Z are each a C1-10 alkyl group which may be substituted with a halogen atom, a C6-20 aryl group, a C6-20 aryloxy group, a C6-20 arylthio group, a C8-20 arylalkenyl group, a C7-20 arylalkyl group, a C2-20 heterocyclic group, or a halogen atom; k is a number of 0 to 4; p is a number of 0 to 8; r is a number of 0 to 4; n is 0 to 10; x is a number of 0 to 4, and y is a number of 0 to 4, with the sum of x and y being 2 to 4; and when n is not 0, the epoxy compound can take the form of any optical isomer.

Description

technical field [0001] The present invention relates to a liquid curable resin composition which is suitable for producing cured products of high refractive index resins, has excellent handling properties, and has little coloration after curing. Background technique [0002] Epoxy resins (compounds) have been actively developed in the fields of electronic materials and optical materials due to their excellent electrical properties, heat resistance, and adhesive properties of cured resins obtained by combining them with curing agents. . For example, in the field of electronic materials, semiconductor sealing materials, etc. are mentioned, and in the field of optical materials, antireflection films such as liquid crystal displays, protective films of color filters, optical waveguides, and optical devices such as cameras are used. Lenses, mirrors and prisms etc. In particular, a high refractive index is required for the purpose of weight reduction in optical material applicat...
