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