Abstract
1296547 Pressure-sensitive record sheets FUJ1 PHOTO FILM CO Ltd 11 Nov 1969 [13 Nov 1968] 55124/69 Heading D2B Pressure-sensitive recording material comprises two sheets of which the first has coated, both on the same side, two colourless colourreactants, and the other has coated on one side one of the reactants, so that when they are pressed together images are formed on both. One or both of the reactants may be in microcapsules or a rupturable membrane may be provided between them. One may be leucomethylene blue or a phthalide and the other a clay, or one a vanadium compound and the other a hydroxy compound. The support sheets may be of paper or plastics film.
