Abstract
A heat-sensitive recording material with an excellent recording sensitivity, heat stability and resistance to the whitening phenomenon, comprising a heat-sensitive color developing layer formed on a substrate sheet and containing, in addition to a colorless dye precursor, color developing agent and binder, a heat-fusible sensitizing agent consisting essentially of at least one member selected from 1,4-bis(p-tolyloxy)benzene, 1,4-bis(3', 4'-dimethylphenyloxy)benzene and 1,4-bis(3',5'-dimethylphenyloxy)benzene, in an amount of 10% to 1,000% based on the weight of the color developing agent.
