Provided is a method for producing a light-blocking material for optical devices which is provided with a light-blocking film achieving low gloss while maintaining the necessary physical properties of a light-blocking film, i.e. light-blocking properties, even when the light-blocking film is formed extremely thinly. In the method for producing the light-blocking material for optical devices which is provided with the light-blocking film, a coating liquid including at least a binder resin, black microparticles, and a dye is prepared. A dye including a metal such as chrome oxide, iron oxide, or cobalt oxide is preferably used as the dye. The coating liquid is subsequently applied to a base material, and dried to form the light-blocking film. |
