ABSTRACT:
A method of preparing a color developer sheet for pressure-sensitive recording is described. The method comprises preparing Coating Solutions A and B separately. Coating Solution A is prepared by dissolving an aromatic carboxylic acid metal salt in an organic solvent and emulsifying the resulting solution in water. Coating Solution B is prepared by mechanically dispersing an aromatic carboxylic acid metal salt in an aqueous system. Coating Solutions A and B are then mixed in such a manner that the weight ratio of the amount of the aromatic carboxylic acid metal salt in Coating Solution A to that of the aromatic carboxylic acid metal salt in Coating Solution B is from 10:90 to 90:10. The resulting mixture is then coated on a support. This color developer sheet shows high developing ability and a high color-forming rate, produces a colored member of high light resistance, and when used as an intermediate sheet, is reduced in the formation of fog.
