    • PURPOSE:To obtain a material for attaining a recording image in which quinoid dye having a specific structure is used as infrared absorption dye and which has high sensitivity, white skin and high quality in a thermal recording material having a heat sensitive layer containing first colorless color developing ingredient, second colorless color developing ingredient for color developing in reaction with the first ingredient and infrared absorption dye and provided on a support. CONSTITUTION:A thermal recording material comprises a heat sensitive layer containing at least a substantially colorless color developing ingredient A, a substantially colorless color developing ingredient B for color developing in reaction with the ingredient A, and an infrared absorption dye arranged on a support, wherein the absorption dye uses quinoid dye represented by a formula I or II. In the formula II, Z is substituted or non-substituted aliphatic cycle or heterocycle having 5-7 members, and in the formulae I and II, R is H, substituted or non-substituted 1-6C alkyl group or alkoxy group, 5-10C aryl group or hetaryl group, m is integer of 0-4, and n-integer of 0-2.
