Abstract

In the manufacture of material for producing visual records, a coating composition is prepared by thoroughly mixing with an aqueous solution of a dryable binder, particles of different solid reactant substances, one being an organic substance (especially an aromatic amine) and the other an inorganic substance (especially a clay), the two substances having such characteristics that a distinctive colouration is produced by mutual contact between them. Preferably the two reactant substances are dispersed in separate quantities of the binder in solution (in the case of the organic substance advantageously by precipitating it in the said solution) and the two dispersions are then mixed, but it is also possible to disperse the two substances in the same solution, provided that they are added separately and the first stirred in before the second is added, and that care is taken in the mixing to avoid rendering ineffective the protective influence of the solution. In an example, a solution of malachite green lactone in dilute hydrochloric acid is added to an aqueous solution of methyl cellulose containing sufficient ammonia to neutralize the acid and precipitate the malachite green lactone, and the resulting dispersion is added to a dispersion prepared by adding a slurry of kaolin in water, containing a dispersing agent such as sodium metaphosphate, to an aqueous solution of methyl cellulose. In further examples the methyl cellulose is replaced by casein and the malachite green lactone by 3 : 3-bis-(p-hydroxy-, amino-, ethylamino- or diethylamino-phenyl)-phthalide, the colourless base or the colourless carbinol base of Rhodamine B, fluorescein or its diacetate, tetrabromophenolsulphonephthalein, tetrabromophenolphthalein, the colourless carbinol base of malachite green or of pararosaniline, the imino anhydride of pararosaniline base, Michler's hydrol or its methyl ether, di- or tri - (p - dimethylamino) - triphenylmethane, anisylidenecinnamylideneacetone or cinnamylideneacetophenone. Other suitable binders are starch, gelatine, polyvinyl alcohol, hydroxyethyl cellulose, animal glue and water-soluble gums such as gum arabic, whilst additional inorganic reactant substances specified are aluminium oxide and phosphate, bentonite, calcium chloride, fluoride, carbonate, oxide and sulphate, magnesium carbonate, silicon dioxide and zinc sulphide. Specifications 546,749 and 628,960, [both in Group VIII], are referred to.
