Abstract
An ink-jet recording film capable of exhibiting excellent ink fixing behavior in ink-jet printing with a water-base ink along with good water resistance of the recording layer, which has a double-layered structure, as formed on the surface of a plastic substrate film, consisting of (A) an ink-receptive layer comprising a water-soluble resin, e.g., polyvinyl alcohol, polyvinyl acetal and/or polyvinyl pyrrolidone, a surface-roughening agent which is a combination of two different silica powders distinguishable in the low and high values of oil absorption in a specified weight proportion and a crosslinking agent for the water-soluble resin and (B) an overcoating layer for dot-profile control consisting of an acrylic resin of the quaternary ammonium salt type.
