Method for separating and recovering laminate

Problem to be solved: To provide a method for separating and recovering a laminate which is excellent in releasability of a printed layer and an adhesive layer even under a condition that the amount of the printed layer during desorption treatment is large, suppresses re-adhesion of a desorbed printed layer component, and is suitable for plastic recycling. And to provide a method for producing a high-quality molding material obtained by heating and molding the recovered plastic base material. Solution: a laminate having at least a plastic base material layer and a printing layer is immersed in a desorption liquid, the printing layer is desorbed so that a median diameter (D50) on a volume basis of a printing layer component desorbed from the plastic base material layer becomes 1 micro m or more, And recovering the plastic base material, wherein the amount of the printing layer is 0.01 mass percent or...
