  • Production of a color developing record sheet containing metal-modified novolak resin particles
    Patent number: 4082713
    Abstract: Rheologically stable aqueous dispersions of metal-modified novolak resin particles are prepared by grinding an aqueous mixture of the metal-modified novolak resin and anionic polymeric dispersing agent in the presence of a small amount of an organo-phosphorus compound containing two or more phosphonic acid or alkali metal phosphonate groups per molecule. Dispersions of the metal-modified resin particles so produced may be incorporated in color developing coating compositions containing a binder which may be applied and dried on a carrier paper to produce a pressure-sensitive record sheet.
    Type: Grant
    Filed: March 21, 1977
    Date of Patent: April 4, 1978
