摘要:
A production process for an optical information recording medium to produce an optical information recording medium comprising a multi-layered recording layer including a recording thin film layer which exhibits a phase transition between the crystal phase and the amorphous phase formed on the substrate and a protection layer of a curing film including an ultraviolet ray curing resin as the outermost layer, further comprising a step of annealing to completely cure the protection layer after the initial crystallization process.
