Abstract

An internal phase solution for a coating of rupturable material for application to a base sheet to form a pressure-sensitive record material comprises one or more colour-formers of which at least 90 % are monoamino and/or diamino fluoran derivatives dissolved in a solvent comprising 80 % to 100 % of one or more vegetable and/or animal oils. Preferably the colour-formers comprise only monoamino and/or diamino fluoran derivatives and the solvent comprises only one or more vegetable and/or animal oils. Dissolution of the colour-formers in the solvent may take place at a temperature in the range 100 °C to 135 °C and micro-capsules containing, such a colour-former solution may be formed by conventional coacervation processes below 70 °C.
