MULTI-CARBON MATERIAL FOR PRODUCING TYPE

摘要

A multi-carbon material as used, for typewriter ribbons, printing blankets or carbon paper for producing type is provided. The material consists of a backing foil upon which is applied a colour releasing coating in the form of a matrix of synthetic material having dispersed therein an oil based colouring substance containing dyestuffs, pigments or mixtures thereof. The oil base for the colouring substance is a surfactant containing a polyoxyethylene group. The surfactant is also a plasticizer for the matrix of the synthetic-material bonding agent. The colour releasing coating contains finely divided fillers having a high specific surface and a particle size of 0.2 to 20 .mu.m. The material of the present invention exhibits substantially increased colouring power.
