PURPOSE:To obtain speedily a recording material superior in rolling property, state of surface and multisheet-transferring property by providing a layer containing a color-forming agent on the raw paper coated with a layer of a color-developing agent by a specified method. CONSTITUTION:On the paper which has such measured quantities of raw paper as 45g/m<2> or less in weight and 1.5m or more in width and is coated with a layer of a color-developing agent (inorganic or organic acid, polyvalent metallic salts thereof etc.) on one surface thereof, a coating liquid which contains microcapsules, preferably, of 3.9-6.5mu in diameter of the particle averaged in volume (containing compounds whose rings are opened and divided, being in touch with the color-developing agent such as lactone and lactam, as color-forming agents) and has the ratio of a binder (e.g. styrene-butadiene rubber latex etc.) to the solid part in a coating liquid for a layer of color-forming agents, preferably, of 6-20wt% is coated at the coating speed of 340m/min. or more, thereby the aimed paper having intermediate thickness and the coated-paper air permeability of 1,000 sec. or less being obtained. |
