Abstract
Abstract A sensitized sheet for a pressure sensitive copy system is obtained by coating the surface of a support with an acceptor composition comprising a particulate mixture comprising an organic acid substance selected from the group consisting of aromatic carboxylic acids and polyvalent metal salts thereof, and an organic high molecular compound. The above coating composition may further contain an inorganic solid particle such as oxides, hydroxides and carbonates of a polyvalent metal, and other mineral pigments. The coating procedure may be carried out with use of coating means mounted on the conventional paper machines.
