The recording material comprises a base sheet and a color former coating layer formed on a surface of the base sheet and the color former coating layer is formed by coating a surface of the base sheet with a coating composition comprising an aqueous dispersion of microcapsules each encapsulating a hydrophobic color former material therein and having a capsule wall of a gelated hydrophilic colloid material. The dispersion further includes (a) a hardener for the hydrophilic colloid material and (b) a water soluble alkali salt of a copolymer of at least one olefinic monocarboxylic acid with at least one monomer copolymerizable with the olefinic monocarboxylic acid. |
