Abstract: PURPOSE:To obtain a transfer sheet having a high sublimation rate and excellent in image stability after transfer by using an ink compsn. prepared by compounding coloring matter for thermal transfer recording represented by a specific general formula, a binder resin and a solvent. CONSTITUTION:An ink compsn. for thermal transfer recording is prepared by compounding yellow coloring matter for thermal transfer recording represented by formula (R is a 3-8C branched or cyclic substituted or non- substituted alkyl group and R is a 5-10C branched or cyclic substituted or non-substituted alkoxyalkyl group), a binder resin and an org. solvent and/or water. This ink compsn. is applied to the single surface of a base material sheet and dried to form a coloring matter support layer to obtain a transfer sheet. When thermal transfer recording is performed, the transfer sheet is superposed on a material to be recorded and heated and pressed according to a recording pattern from the back surface of the transfer sheet by a thermal recording head to transfer the coloring matter on the transfer sheet to the material to be recorded.
