Abstract
Abstract A photo and pressure sensitive recording medium comprising a base sheet, supporting thereon a color developing agent which reacts with a dye precursor to develop color and an adhesive substance with which the recording medium may be adhered to any suitable material or body. The color developing agent may be coated on one surface of the base sheet and adhesive is applied on the other surface of the base sheet. The adhesive substance may be of thermoplastic type or enveloped in microcapsules crushable under pressure. A peel-off sheet may be conted on the adhesive substance. Alternatively, the color developing agent and the adhesive substance may both be supported on one surface of the base sheet, as well as photo-curable microcapsules containing the dye precursor. The adhesive substance may also be enveloped in microcapsules which are ruptured under pressure to flow out the contained adhesive, with which the recording medium is bonded to a general-purpose sheet such as ordinary paper to provide a one-body recorded sheet.
