Abstract
Abstract A heat-adhesive paper sheet suitable for use as fusuma paper and shoji paper in a Japanese style house, wallpaper, ceiling paper, liner for paintings and calligraphic works, and liner for plywood, and which is adhered to the object with heat by ironing. The heat-adhesive paper sheet is composed of a paper sheet material having a projection-depression pattern formed on the surface thereof by creping or embossing or the like and a layer of a thermoplastic thermal shrinking pressure-sensitive adhesive provided on one surface of the paper sheet material. Even though the surface of the object to which the paper sheet is stuck is somewhat rough and uneven, the heat-sensitive adhesive layer may easily be fused so that the paper sheet may be well applied to the object under light pressure without forming wrinkles on the applied sheet. Steam ironing, which has heretofore been unacceptable, is applicable to this paper sheet for sticking it to an object.
