Pressure sensitive record material carries two coatings one of which is a base coat of a phenolic resin colour developing composition, and the other a topcoat of substantally non-reactive pigment material which is bound on the surface of the colour developing composition. The non-reactive topcoat eliminates the accumulation of contaminants on the fuser roll of copier/duplicators when the record material is printed by photocopier or laser printing operations. |
