PROBLEM TO BE SOLVED: To provide a resin layer removal method that, when a resin layer is removed from a composite made by forming the resin layer on a glass substrate, can remove the resin layer from the glass substrate without heat treatment at a high temperature, and thus can simplify treatment without significant alteration of equipment to enable improvement of productivity at the recycle of the glass substrate, reduction of treatment cost and the like.SOLUTION: A resin layer removal method for removing a resin layer disposed on a glass substrate includes a step of bringing an alkaline aqueous solution, having an alkali concentration of 15 mass% or more and containing 3 mass% or more of a compound represented by formula (1), into contact with the resin layer to remove the resin layer. RO-(LO)-H (1) (In the formula (1), R represents an alkyl group; L represents an alkylene group; and n represents an integer of 1 or more.) |
