PURPOSE:To obtain pressure sensitive recording sheet whose coloring speed is high, suitable for non-impact printer by including aliphatic triglyceride together with metallic salt of aromatic carboxylic acid in an electron accepting coloring material layer. CONSTITUTION:A coloring material is dispersed with water mechanically by a ball mill, an attrition mill, and a sand grinder together with pigment, dispersant, water soluble macromolecule and other additives so as to obtain coloring material dispersant. As a method for adding aliphatic triglyceride expressed by a general formula (I) in a coloring material layer, the coloring material is added together with the pigment, the dispersant, the water soluble macromolecule and the other additives when it is to be dispersed with water mechanically by the ball mill, the attrition mill, and the sand grinder. |
