Abstract: Pressure-sensitive record material exhibiting particularly efficient colour former utilization comprises a top sheet having solid colour former material coated on its underside and a bottom sheet having solid colour developer material and solvent-containing microcapsules coated on its upper side. The colour former coating may be applied by means of a printing press in all-over or selective fashion without the occurrence of transparentizing, setoff or blocking.

Abstract: A chromogenic compound of normally colorless form is disclosed having the following structural formula: wherein A and B can be X and Y can be aryl and heterocyclic, each substituted Z is hydrogen and E can be tetrachloro-and tetrabromo-substituted STRUCTURES. The compound is eligible for use in pressure-sensitive record materials and manifold marking systems. Because of light absorption characteristics, selected compounds of this invention are especially useful where machine readability and machine copiability are important.

Abstract: 1,129,430. Making microcapsules. NATIONAL CASH REGISTER CO. 29 June, 1967 [22 July, 1966], No. 29994/67. Heading B8C. Microcapsules are prepared by establishing an agitated coacervatable solution of wallforming polymeric material, dispersing the core material (solid or liquid) therein, and causing the co-acervate phase of wall-forming material to form in the system at a controlled rate which is substantially equal to that at which it deposits on the core material, thereby avoiding the presence of substantial amounts of undeposited coacervate phase and the " clumping " of capsules. The capsules formed are subsequently hardened by conventional procedures, either physical or chemical. Specific examples relate to the encapsulation of a solution of a dye in chlorinated biphenyl, which is dispersed in a gelatin/gum arabic solution at pH 9 to which a solution of polyvinylmethyl ether/maleic anhydride copolymer sodium salt in water/ethylmethylketone and acetic acid is gradually added to induce coacervation. Reference is also made to the encapsulation of various animal, vegetable, mineral and synthetic oils and to pharmaceuticals, e.g. riboflavin, salicylamide, tetracycline HCl, tetracycline phosphate, phenaglycodol, chlorotrianisene, cholesterol, meprobamate, erythromycin propionate, benzathine penicillin G and vitamin K.

Abstract: 1,242,833. Colour-reactive record and copy sheets. NATIONAL CASH REGISTER CO. 7 Jan., 1970 [21 Jan., 1969], No. 791/70. Addition to 1,161,386. Heading D2B. [Also in Divisions C2 and C4] Colour formers for use with acidic coreactants in pressure sensitive copying papers comprise 5- and 6-methyleniminophthalides of the formula in which R is a 1,2-dimethylindol-3-yl or pdialkylaminophenyl group, R 1 is an optionally substituted aromatic carbocyclic or heterocyclic group having at least one double bond conjugated with the imino double bond and R 2 is hydrogen or a C 1-4 alkyl group. Specified acidic components are phenolic resins and attapulgite clays. The phthalides develop colours in the grey-black range including blues and greens.
