PURPOSE:To obtain a thermosensible recording material which has a long period storage property of colored images and a good oil resistance by adding into a thermosensible recording layer at least a kind of compound selected from specified maleimide compounds, compounds having a pyrazoline skeleton, pyrone compounds, bisphenol derivatives, etc. CONSTITUTION:At least one compound selected from the following compounds is contained in the thermosensible recording layer of a thermosensible recording material: a kind of maleimide compound expressed by a formula I, where R1 is selected from H, alkyl, alkoxyl, and aryl groups; a comound having a pyrazoline skeleton represented by a formula II, where R2 is a ring group including an aryl group having a single or condensed ring, R3 and R4 are selected from alkyl and alkoxyl groups, etc.; a pyrone compound shown by a formula III, where R5 is a bivalent group of 3-8C and Ar is an aromatic ring; and a kind of bisphenol derivative indicated by a formula IV, where R is an alkyl group, A is (CH2)nS, n is an integer of 1-9. |
