THERMOPLASTIC RESIN COMPOSITION, HEAT-SENSITIVE ADHESIVE SHEET AND METHOD FOR PRODUCING HEAT-SENSITIVE ADHESIVE SHEET

摘要

PROBLEM TO BE SOLVED: To obtain a thermoplastic resin composition of which the hest-sensitive adhesive sheet is easily peeled off by an alkaline solption without leaving an adhesive on an adherend and without spoiling appearance when the adhesive sheet is made to adhere to the adherend when used as the adhesive of the adhesive sheet. SOLUTION: This thermoplastic resin composition comprises a thermoplastic resin and a solid plasticizer and the thermoplastic resin has 2-30% soluble fraction in tetrahydrofuran. Melting point of the solid plasticizer is preferably 70-120 deg.C and the content of the solid plasticizer is preferably about 30-1,000 pts.wt. based on 100 pts.wt. of the thermoplastic resin. The thermoplastic resin composition may further contain a tackifier.
