HEAT-SENSITIVE RECORDING SHEETS

摘要

A heat-sensitive recording sheet comprises a paper support having a heat-sensitive color forming layer on one side and an antistatic layer on the other side. The antistatic layer contains at least one homopolymer or copolymer of a vinyl compound having a sulfonic acid group and a weight-average molecular weight of at least 5,000, and at least one surfactant selected from sulfosuccinates, alkylbenzenesulfonic acid salts and naphthalenesulfonic acid salts. This recording sheet has improved in print running properties under low humidity conditions.
