ABSTRACT:
A color-developing sheet for pressure-sensitive copying paper sheets is obtained using an aqueous suspension of a color-developing composition containing a multivalent metal salt of a salicylic acid resin obtained from a salicylic acid ester and a mixture of styrenes which include a styrene dimer, which aqueous suspension is obtained by finely wet-grinding the color-developing composition in the presence of at least one anionic, water-soluble, high-molecular weight substance selected from (a) polyvinyl alcohol derivatives containing at least one sulfonic acid group thereof and salts thereof and (b) polymers and copolymers containing as an essential component a styrenesulfonic acid salt.
