ABSTRACT:
Disclosed is a holographic optical recording medium, comprising a recording layer containing a three dimensionally cross-linked polymer matrix, a radically polymerizable compound, and a photo radical polymerization initiator, the three dimensionally cross-linked polymer matrix comprising a cured material of a reaction product between a diglycidyl ether and an amine, the diglycidyl ether being selected from the group consisting of 1,6-hexanediol diglycidyl ether and diethylene glycol diglycidyl ether.
