    摘要： It is an object of the present invention to provide a method for producing a lithographic printing plate without any deterioration in plate making performance caused by deformation and breakage of fine particles. An inorganic compound dispersion as a coating liquid is applied onto a surface of a strip-shaped flexible support at a pressure P applied to the coating liquid of 1.5×105 Pa or less to form a coating layer. Also, an inorganic compound dispersion as a coating liquid is applied onto a surface of a strip-shaped flexible support at a shearing stress τ applied to the coating liquid of 1.5×105 Pa or less to form a coating layer.
