Abstract
A light amount adjustment member, which causes little deterioration of image quality by diffraction at a grain boundary between ink dots in a colored portion, can be simply produced at low production cost and high yield. The light amount adjustment member has a density distribution such that an optical density varies continuously or stepwise. The process comprises steps of providing a transparent base material having a receptive layer comprised of a material capable of absorbing a coloring liquid and containing a resin and crosslinking agent, applying the coloring liquid to the layer using an ink-jet recording method to form a light amount adjustment region having a particular optical density region, storing the layer under a prescribed environment after application of the coloring liquid to the layer to cause dots formed by the coloring liquid to bleed and crosslinking the resin contained in the layer by the crosslinking agent.
