    摘要: The invention describes a composition and method of providing an improved recording material, such as an ink receptive recording material or thermally responsive record material useful for linerless labels. The record material comprises a support having provided thereon on one surface an adhesive material, and on at least one other surface, an ink receptive coating or a heat sensitive imaging coating. The method comprises applying to a first surface a first layer of a coating of an ink receptive material or of a heat sensitive color-forming composition comprising a binder material and a substantially colorless dye precursor and an acidic developer material in substantially contiguous relationship. The adhesive is heat activated. The record material exhibits substantially no tack at 23° C., 40% relative humidity when pressure is applied, however develops high peel strength (300 grams/inch) upon application of 7 mJ/mm2 to 13 mJ/mm2 of heat energy.
