摘要： A colour reactant component for coating a receptor sheet of the kind used in copying paper systems is produced by incorporating in an aqueous slurry of an inorganic mineral at least one soluble salt of the metals cobalt, cerium, copper, iron, manganese, lead, indium, lanthanum, barium, antimony, beryllium, strontium, nickel, zinc, calcium cadmium, magnesium, chromium, and tin, and at least one soluble aluminate salt, so as to precipitate at least one insoluble aluminate compound in the slurry, and thereafter incorporating a binding agent selected to bond the colour reactant component to the receptor sheet.

摘要： In copying paper for use in a pressure-sensitive copying system of the kind in which copying is effected by reacting together a colour-former and a colour-reactant, the colour-reactant is formed by fine particles of oil-absorptive, inorganic, mineral material, the particles being individually coated, at least in part, with an organic, acidic, oil-soluble polymer containing uncombined phenolic hydroxyl groups, said polymer being reactive with the colour-former to develop it to the coloured form. The polymer may be a phenol/formaldehyde or a phenol/acetylene polymer and the mineral particles may consist of silicates, alumino-silicates, silica, alumina or silica/alumina mixtures. In one example they are kaolin.
