Recording medium.

摘要

A recording medium which comprises a support having thereon a layer containing an electron-donating achromatic dye incorporated in microcapsules and an electron-accepting compound, wherein said electron-accepting compound is a 3-halo-4-hydroxybenzoic acid ester having a polymerizable ethylene group. The recording medium provides a high color density at image part, a low fog density at non-image part and markedly high stability of the non-image part.
