Embodiment

[0046] The components shown in Table 1 were mixed to obtain a resin composition. In Examples and Comparative Examples, the bisphenol A type epoxy resin is RE-3105 manufactured by Nippon Kayaku (Co., Ltd.), and the alicyclic epoxy resin is two (3,4-epoxycyclohexyl) adipate ( Union Carbide UVR-6128) and γ-glycidoxypropyltrimethylsilane were used as the silane coupling agent.

[0047] As a photocation initiator, as a "fast curing initiator" in the table, the compound [tetrakis(pentafluorophenyl)boronic acid {methyl-4-phenyl(methyl-1- Ethyl)-4-phenyl}iodonium salt (tetrakis(pentafluorophenyl)borate-{methyl-4-phenyl(methyl-1-ethyl)-4-phenyl}iodoniumsalt)], as "slow curing initiator", use Mixture of formula (C-5) and formula (C-6) (Union Carbide CYRACURE(TM) Photoinitiator UVI-6990).

[0048] As silica, silica having a specific gravity of 2.635 and an average particle diameter of 1.5 μm was used.

[0049] As talc, talc having a specific gravity of 2.70 and an average particle dia...

Abstract

A photo-induced cation curable epoxy resin composition which comprises (a) an epoxy resin component containing an alicyclic epoxy resin and an epoxy resin having an aromatic ring, (b) a photo-cationic initiator and (c) a filler selected from the group consisting of the oxides, hydroxides and carbonates containing a 2 group element of the long periodic table of elements. The composition can be used as an adhesive exhibiting high adhesiveness toward a glass, particular an alkaline glass, or a metal.

Description

technical field [0001] The present invention relates to photocurable resins, and more particularly, to epoxy resin compositions curable by cationic polymerization upon exposure to light. Background technique [0002] The photocation-curable epoxy resin composition, which is cured by cationic polymerization of epoxy resin by irradiation of light, especially light in the UV range, has the same cured properties as the thermosetting type, and has the same characteristics as radical UV curing. Compared with the free radical UV curing type, it is not hindered by oxygen and has a smaller shrinkage rate than the radical UV curing type. It is known to be used for liquid crystal display applications and DVD lamination applications. [0003] The resin composition contains a photocation initiator. Photocation initiators are usually expressed in the form of salts, when using A + B - When expressed, it is known that because of its anion B - Depending on the type of resin, the curing s...
