  • Color-developer coating for use in copy systems
    Patent number: 4087284
    Abstract: A process for preparing color-developer coatings in which an oily solution of an acidic, organic material is emulsified in water and an insoluble, particulate, oil-adsorbent material is dispersed in the emulsion. The resulting emulsion-dispersion may be coated onto a receptor such as a paper substrate or other receiving surface and dried. The product resulting from the process is an enhanced color-developer coating for use in pressure-sensitive copy systems.
