    摘要: Pressure-sensitive copying material utilizes a blend of rapid- and slow-developing chromogenic materials in vegetable oil solvent and an acid clay or synthetic inorganic color developer. The surface pH of the color developer is not more than 8.7, which gives rise to enhanced image intensity and fade resistance compared with the use of conventional higher color developer surface pH values.

    摘要: Pressure-sensitive copying material comprises 3,1 benzoxazine chromogenic material(s) in a solvent comprising vegetable oil and/or a mono-, di or tri-functional ester of a non-aromatic mono-carboxylic acid having a straight or branched hydrocarbon chain with at least three carbon atoms in the chain in addition to the carboxyl carbon atom and an inorganic colour developer. The surface pH of the colour developer is not more than about 8.7, which gives rise to enhanced image intensity and fade resistance compared with the use of 3,1 benzoxazine chromogenic materials in the same solvent with the same colour developer at higher surface pH values.

    摘要: A chromogenic composition for use in pressure-sensitive record material comprises chromogenic material in an ester vehicle. The ester may be mono-, di- or tri-functional and is of a non-aromatic mono-carboxylic acid having a straight or branched hydrocarbon chain with at least three carbon atoms in the chain. Suitable esters include fatty acid esters such as cocoates, isostearates, myristates, and palmitates and wax esters such as alkyl-branched esters of an aliphatic carboxylic acid and an aliphatic alcohol.
