Abstract: 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.

Abstract: The process applies microscopic capsules to paper etc. by a pressure system. The paper with the capsules is used for copying without the use of carbon paper. The capsules are pressed into the paper in the form of a watery dispersion or dye by means of a roller or plate coated with foam or cellular rubber, the latter having open cells ont he working side. Th design gives, compared with existing methods, a sufficient and even distribution of the capsules over the paper.

Abstract: A pressure-sensitive and heat-sensitive recording material which comprises a carrier bearing a color-developing coating consisting of (a) a finely divided solid phenolic resin with spherical particles of size where R1 is C8-C20-alkyl, phenyl or C1-C20-alkylphenyl, R2 is hydrogen or methyl, n is from 2 to 100 and m is from 0 to 50, and ( beta ) an ethylenically unsaturated copolymerizable carboxylic acid, sulfonic acid or phosphonic acid, with or without ( gamma ) an additional ethylenically unsaturated copolymerizable compound different from ( alpha ) and ( beta ), and (c) one or more aliphatic alcohols which are solid at room temperature, with or without (d) other auxiliaries. The coating, used in conjunction with micro-encapsulated color formers, gives sharp and intense copies.
