PURPOSE:To obtain a color picture having excellent hue, high density, excellent picture stability such as fixing properties, optical resistance, etc., by providing a layer containing colorants for forming nitrogen-containing organic base and salt on a support to form a heat sensitive transfer material. CONSTITUTION:When metal sources are present in an image receiving layer 2 of an image receiving material 3 made of a support l and the layer 2, colorants in a heat sensitive transfer layer 5 of a heat sensitive transfer material 6 made of a support 4 and the layer 5 are diffused to be shifted to the material 3 by means of heat from a heat generating resistor 8 of a thermal head 7. It is reacted with the sources in the layer 2 to form a chelate colorant picture. The colorants contained in the layer 5 of the material 6 are those capable of forming salt with nitrogen-containing organic base such as azo colorant, azo methine colorant, anthraquinone colorant, etc. In order to form the salt with the organic salt while holding high sensitivity, colorant having phenolic hydroxyl group is desirable. |
