EPOXY RESIN COMPOSITION AND OPTICAL INFORMATION RECORDING MEDIUM MADE BY USING THE SAME |
| 摘要 |
<p>An epoxy resin composition according to the present invention is one initiating cationic polymerization upon irradiation with energy rays. The epoxy resin composition is formed of at least bisphenol type epoxy resin (A) as an active ingredient, epoxy resin (B) shown in the following formula and cationic polymerization catalyst (C). The epoxy resin composition can improve the thermal resistance of the adhesive layer in an optical information recording medium, and the adhesive property of the adhesive layer is not lowered even if its hardness is increased or it is in high humidity. <CHEM> where R is <CHEM></p> |
