PROBLEM TO BE SOLVED: To obtain a moisture-curing hotmelt adhesive in which, before curing, separation is easily accomplished between an adhesive layer and a base material for the reuse of the base material and, after curing, a cosmetic material is manufactured which has a firm adhesion between the base material and a coating material, and to provide a method for manufacturing the cosmetic material. SOLUTION: The moisture-curing hotmelt adhesive is prepared by a reaction of two or more resin components and a resin component binder, and is nonviscous at normal temperatures. One of the resin components comprises a part that is solid at normal temperatures and a part that is liquid at normal temperatures and has a glass transition point of≤0°C, and the solid part and the liquid part before reaction are incompatible with each other at normal temperatures. For manufacturing the cosmetic material, the moisture-curing hotmelt adhesive is applied to the coating material and the coating material is attached to the base material with the adhesive layer in between. In case of a faulty attachment, the coating material is separated before the moisture-curing reaction from the base material for the reuse of the base material. COPYRIGHT: (C)2005,JPO&NCIPI
