A recording film suitable for dual recording first by ink jet patterning to form a base image pattern in a recording layer and then by a pen plotter to write an add-on information image thereon, consists of a substrate film, an ink-receptive layer on the substrate surface and a dot configuration-controlling layer on the ink-receptive layer. The ink-receptive layer is formed from a coating composition comprising a polyvinyl alcohol, a polyvinyl pyrrolidone, an inorganic powder such as a combination of silica and calcium carbonate powders for surface roughening, and a crosslinking agent such as a urea resin; while the dot configuration-controlling layer is formed from an acrylic resin of the quaternary ammonium salt type. The surface of the recording layer has a surface roughness of 0* small Greek psi *8-1* small Greek psi *5 ~m. |
