Heat-sensitive recording material.

摘要

A heat-sensitive recording material is prepared by forming a heat-sensitive recording layer on a synthetic paper having a laminated structure. The synthetic paper has a front surface having a smoothness (in accordance with JIS P-8119) of not less than 2000 seconds on which the heat-sensitive recording layer is provided, and a back surface having a smoothness of not more than 1000 seconds, and has an opacity (in accordance with JIS P-8138) of not higher than 40 %. The heat-sensitive recording material is superior in recording runnability and recording quality, and gives recorded materials useful as a second original for diazo print. <IMAGE>
