| 发明名称 | Epoxy resin composition for transparent sheets and cured product thereof | ||
| 摘要 | A cured product obtainable by curing an epoxy resin composition that is suitable for producing optical sheets. The epoxy resin composition includes a polyvalent carboxylic acid (A) represented by formula (I):; wherein, R1's each independently represent a hydrogen atom, an alkyl group having 1 to 15 carbon atoms, or a carboxyl group; q represents the number of substituent R1's, and represents an integer from 1 to 4; and P represents the following X: ; wherein there may be a plural number of R2's per ring, and R2's each independently represent a hydrogen atom or a methyl group; and * represents a bonding site linked to the oxygen atom; and an epoxy resin (B) having an aliphatic cyclic structure in the molecule. | ||
