Abstract
PURPOSE:To manufacture a subject sheet having a white texture and having no texture coloration by adding an organic solvent into dispersing liquid of a coloring compound, removing the organic solvent and thereafter mixing a dispersing liquid of a phenolic compound, and applying the mixed dispersing liquid on a substrate. CONSTITUTION:(A) A phenolic compound such as bisphenol A, a low molecular weight novolak resin or the like is dispersed in an aqueous binder agent solution. (B) Separately from this, a colorless or pale coloring compound coloring by a reaction with the phenolic compound is dispered in an aqueous solution of an aqueous binder solution and pulverized into a particle having a diameter of from 1-5mu. Thereafter, an organic solvent such as methyl alcohol, acetone or the like is added to the solution in a ratio of 20-150% (with respect to the solid content), and the solution is agitated to remove the organic solvent. Then the solution (A) is mixed with the solution (B) to prepare a coating liquid, which is applied on a substrate such as paper or the like.
