Abstract
In producing a recording paper having, on the surface of a support, a coating layer comprising inorganic pigment and aqueous polymeric binder, a recording paper giving a high color density of image, a clear color tone of image and a high resolution and suitable for multi-color recording was obtained by preparing said coating layer by twice or more repeating a step which comprises coating a coating color prepared by mixing 100 parts by weight of said inorganic pigment containing 50-100 parts by weight of synthetic silica with 2-18 parts by weight of said aqueous polymeric binder in an amount of 2-9 g solid/m.sup.2 per one side of the support by one run of coating procedure and then drying the coating color.
