PURPOSE:To obtain a thermal recording material having color forming sensitivity and imparting a developed color image enhanced in storage stability such as hydrothermal resistance, water resistance or oil resistance by adding a compd. having a specific structure in addition to an electron donating compd. and an electron acceptive compd. CONSTITUTION:In a thermal recording material containing an electron donating compd. and an electron acceptive compd., a compd. represented by formula I is further added. As a result, the thermal recording material having good color forming sensitivity and imparting a developed color image enhanced in storage stability such as hydrothermal resistance, water resistance or oil resistance can be obtained. |
