METHOD FOR RESIN RECOVERY

摘要

A method for recovering a resin from a resin plate made by coating at least one side of a water-swellable transparent resin substrate with either a thin-film metal layer or a printed coating layer or both of them, which method comprises the step of rolling the resin plate, the step of swelling the plate, the step of pressing the swollen plate, the step of contacting the pressed plate with hot water, and the step of removing the resin. The method enables the resin component to be recovered from a recording medium (e.g. disk) having a substrate made from a transparent resin such as a polycarbonate resin in a simplified process scarcely causing deterioration, thus permitting recycling thereof.
