description | 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. |
