OPTICAL INFORMATION RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an optical information recording medium having a receiving layer for highly glossy ink jet recording while having high receiving ability.

SOLUTION: In the optical information recording medium having an information recording layer and a light reflection layer on a transparent substrate, the receiving layer for ink jet recording and surface flattening layer are provided in this order on a surface on the side opposite to light incident side of reproduction light reproducing information of the information recording layer. The receiving layer for ink jet recording contains a water soluble resin and fine particles and the surface flattening layer contains inorganic fine particles having 20 to 100 nm average primary particle diameter. The surface flattening layer preferably has 0.5 to 5 μm film thickness.
