摘要： 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.
