PROBLEM TO BE SOLVED: To further improve surface hardness and resistance to UV colorability of a resulting cured product (molded product) when using an alicyclic epoxy resin and to further increase the application range of the molded product, and further to improve Tg which is one of the physical properties of the resulting cured product (molded product) when using a Bis A type diglycidyl ether.SOLUTION: There is used an epoxy resin curing agent represented by the following formula (1): (where, R represents a methyl group, an ethyl group or a hydroxyl group and n is an integer of 1 to 3.) |
