Process for producing a sheet of color-developer for pressure-sensitive recording paper.

摘要

A sheet of a color-developer for a pressure-sensitive recording paper is prepared by: (i) dissolving an organic color-developer in an organic solvent; (ii) adding the solution of the color-developer to an aqueous solution in which a surfactant and a water-soluble polymer are dissolved in a combined amount of from 0.2 to 50 parts by weight per 100 parts by weight of said solution of the color-developer; (iii) emulsifying the so-formed mixture thereby forming minute liquid droplets with a diameter of 0.01 to 2 um comprising said solution of the color-developer; (iv) heating the liquid emulsion under agitation, thereby removing said organic solvent from said liquid droplets and obtaining an aqueous slurry of said color-developer; and (v) applying the aqueous slurry of said color-developer on a supporting sheet. o
