摘要

PURPOSE:To suppress the deterioration of an optical disk due to an adhesive layer during production, use and preservation. CONSTITUTION:Two substrates 3 each consisting of a recording film 2 and a transparent substrate 1 are coated with an adhesive contg. 95-75% UV-curing monofunctional acrylic resin and 5-25% UV-curing epoxy resin to form adhesive layers 4.
