Abstract
A composition for forming pressure- and heat-sensitive coatings comprising finely divided organic material of particle size from about 0.05 to 10 micrometers in diameter having a melting point above about 150.degree. C., the particles being of substantially uniform color and subject to plastic flow by heat or pressure, and a liquid carrier normally including a binder dispersed in the carrier to give a thixotropic gel. The composition optionally includes water-soluble or dispersible dye or a pigment uniformly dispersed in said particles. A method of preparing the compositions comprises precipitating the solid organic material in water, normally incorporating a binder, and optionally incorporating coloring material into the organic material to form a gel-type paste.
