Abstract (en)
[origin: US4371634A] A microcapsule-containing wax composition, which comprises (a) microcapsules of from 2 to 10 mu m diameter, (b) waxes and (c) dispersants, with or without pigments, fillers, volatile constituents and other agents conventionally present in wax compositions for the hot carbon process. The wall material of the microcapsules is a cross-linked urea-melamine condensate. The wax compositions may be applied over all or part of the surface of a base material, and give deeply colored copies with color-forming (CF) layers.
