    摘要： A process for preparing a color developer sheet for pressure-sensitive recording is disclosed. The sheet is comprised of a coating solution on a support, said coating solution being prepared by dissolving an aromatic carboxylic acid metal salt in an organic solvent and then emulsifying the resulting solution in water. The organic solvent is such that the viscosity of a 50% by weight solution of the aromatic carboxylic acid metal salt in the organic solvent falls within the range of from 200 to 4,000 centipoises. This color developer sheet shows a high color-forming rate and its coated surface is free of irregularity and includes a consistent amount of coating material.
