Title:
熱膨張性シートの製造方法
Document Type and Number:
Japanese Patent JP7251571
Kind Code:
B2
Abstract:
To provide a thermally-expandable sheet that can prevent a thermally expansion layer from peeling off from a base material when the thermally expansion layer is expanded, and a method for producing the thermally-expandable sheet.SOLUTION: A thermally-expandable sheet 10 has an anchor layer 12 on one face of a base material 11, and a thermally expansion layer 13 on the anchor layer 12. The anchor layer 12 has excellent adhesiveness to the base material 11 and the thermally expansion layer 13, so that it is possible to prevent the thermally expansion layer 13 from peeling off from the base material 11 when the thermally expansion layer 13 is heated and expanded.SELECTED DRAWING: Figure 1
