SURFACE TREATMENT OF HEAT-SENSITIVE RECORDING PAPER

摘要

A heat-sensitive recording paper which has on a paper support a heat-sensitive recording layer having received a surface treatment in such a state that the recording paper comes to contain moisture in a proportion ranging from 5 wt % to 12 wt % by drying after the coating of the heat-sensitive recording layer. The surface treatment is effected by passing the recording paper through a pressure applying means. The pressure applying means is constructed by metal roller heated up to a temperature of 40 DEG C. to 60 DEG C. and an elastic roller (made preferably of hard rubber). The recording layer is brought into a face-to-face contact with the metal roller.
