ABSTRACT:
A composition for forming pressure- and heat-sensitive coating comprising finely divided organic material of particle size from about 0.001 to 15 micro meters in diameter having a melting point above about 55.degree.C, the particles being of substantially uniform color and subject to plastic flow by heat or pressure, a liquid carrier in sufficient amount to give a fluid system and normally including a binder dispersed in the carrier. The composition optionally includes an oil-soluble dye or a pigment uniformally dispersed in said particles. A method for preparing the compositions which comprises heating to dissolve in a suitable solvent as the solid organic material, cooling the resulting solution to form a paste of the desired particles, normally incorporating a binder, and optionally incorporating coloring material into the organic material.
