PURPOSE:To obtain a developing sheet for pressure sensitive recording which is excellent in both color density and coloring speed by a method wherein a fatty acid amide derivative having metal salt of a salicylic acid derivative and benzotriazole radical as substituents which is represented by a specific general formula, is contained in a same layer. CONSTITUTION:A developing sheet for pressure sensitive recording by containing a fatty acid amide derivative having metal salt of a salycilic acid derivative and benzotriazole radical as substituents which is represented by a general formula I (in the formula, radicals expressed by R1, R2, R3 and R4 represent hydrogen atom, alkyl radical, or aryl radical.) in a same layer. Further, as the fatty acid amide derivative having a benzotriazole radical as a substituent, that having 3-(2H-benzotriazole-2-yl)-2-hydroxy-1-alkylbenzene skeleton in a molecule is used. A pressure sensitive recording material using the developing sheet is excellent in both color density and coloring speed in either cases at room temperature and low temperature and is also further excellent in durability at high temperature. |
