A coating aqueous dispersion comprises water and has dispersed therein a pigment and the alkali-process gelatin. A process for producing a recording medium comprises the steps of coating on a support at room temperature the coating aqueous dispersion and drying the resulting coating at a high temperature of 80.degree.
