Abstract

656,859. Pressure-sensitive paper. NATIONAL CASH REGISTER CO. Sept. 22, 1948, No. 24784. Convention date, Nov. 8, 1947. Addition to 629,165. Drawings to Specification. [Class 96] In the process of the parent Specification, the following additional colour reactants are employed ; organic : 3 : 3-bis-[p-dimethylaminophenyl) - 6 - dimethylaminophthalide, tetramethylbenzidine and mixtures of these two substances (e.g. in the proportion of 5.7 : 1 by weight), 4<SP>1</SP> - (p - dimethylaminophenylazo)- benzyanilide, 3 : 3 - bis - (p - - di - n propylaminophenyl) - phthalide, 2 - (41 : 411 - bisdimethylaminobenzhydryl) - 5 - dimethylaminobenzoic acid, 3 :3 - bis - (p - methylaminophenyl) phthalide, 3 : 3 - bis - (41 - dimethylamino - 3<SP>1</SP> - methylphenyl) - phthalide and 2 : 4 bis - [p - (p<SP>1</SP> - dimethylaminoph enylazo anilino] - 6 - hydroxy - 1 :3 : 5 - triazine ; inorganic : attapulgite, barium sulphate, calcium citrate, calcium phosphate, halloysite, magnesium trisilicate, pyrophyllite, talc and zirconium dioxide. Any of the latter substances may be used in conjunction with any of the former or with any of the organic colour reactants enumerated in the parent Specification. Examples describe the use of the specified organic colour reactants with kaolin as inorganic colour reactant and casein as binder. Specifications 546,749 and 628,960, are referred to. The Specification as open to inspection under Sect. 91 comprises also the use of any mixture of two or more organic colour reactants, and the use of o-hydroxybenzalacetophenone as organic colour reactant. This subject-matter does not appear in the Specification as accepted.
