ABSTRACT:
A thermal recording material comprising (1) a synthetic paper support having on one side thereof (2) a thermal color forming layer, the support comprising (B) a biaxially stretched resin film as a base layer having (A) a uniaxially stretched thermoplastic resin film containing from 1 to 8% by weight calcium carbonate powder as a calcium carbon powder containing layer on one side thereof, and (C) a uniaxially stretched thermoplastic resin film containing from 15 to 55% by weight inorganic fine powder as a back surface layer on the other side thereof, the thermal color forming layer being provided on the calcium carbon powder containing layer (A), in which (i) the support has an opacity of not more than 45% as measured according to JIS P-8138, (ii) the calcium carbon powder containing layer (A) has a Bekk's index of from 1,000 to 3,500 seconds and a center-line average roughness (Ra) of not more than 0.5 .mu.m, (iii) the back surface layer (C) has a Bekk's index of from 100 to 900 seconds and a center-line average roughness (Ra) of from 0.6 to 1 .mu.m, and (iv) the support has a density of from 0.91 to 1.1 g/cm.sup.3 as measured according to JIS P-8118. The thermal recording material has improved image definition, including dot reproducibility, is suitable for diazo copying and high-speed printing, and can be written on with a pencil.
