PURPOSE:To obtain a methine coloring matter capable of giving a recording of clear and moderate yellow color having good transferabilty and excellent light resistance as well as a great coloring power in a sublimation type heat-sensitive transfer recording system using a coloring matter of a specific structural formula. CONSTITUTION:A yellow coloring matter for heat-sensitive transfer recording, represented by the formula I (where X is H or methyl and R and R' are each methyl, ethyl, propyl, or butyl), e.g., the compound of the formula II, is combined with adequate dyes of magenta color and cyanine color to obtain a full color recording having good reproductivity. The yellow coloring matter is mixed with an adequate resin, a solvent, and water to prepare an ink, and the ink is coated on a base material to form a transfer sheet. The sheet is superposed on a material to be recorded and heated and pressed from the back of the sheet by means of a heat-sensitive recording head for recording. |
