HEAT-BONDABLE PAPER SHEET

WIPO Patent Application WO/1991/002120

A1

A heat-bondable paper sheet (1) which is appropriate for backing of paper to be used for sliding door, shoji (paper sliding door), wall, and ceiling in a Japanese style house, for writing and drawing, or for plywood, and which can be heat-bonded by the use of heat of an iron. A heat-shrinkable and pressure-sensitive thermoplastic adhesive layer (3) is provided on one side of a sheet (2) roughened by crepe or emboss finishing or the like. Regardless of slight roughness of the surface of a ground sheet to which the heat-bondable sheet is bonded, the heat-sensitive adhesive layer (3) is easily melted with heat and enables bonding without causing creases when the sheet is lightly pressed, whereby bonding with the use of a steam iron which has been impossible up to now is made possible.
