摘要： Provided is a method for producing a light-blocking material for optical devices which is provided with a light-blocking coat achieving low gloss while maintaining the necessary physical properties of a light-blocking coat, i.e. a light-blocking property, even when the light-blocking coat is formed extremely thinly. In the method for producing the light-blocking material for optical devices which is provided with the light-blocking coat, 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 coat.

摘要： A method for producing surface convexes and concaves enabling easy and highly precise formation of desired convex and concave shapes using a photomask is provided.A mask member having light transmitting sections and non-light transmitting sections is disposed over one side of a photosensitive film consisting of a photosensitive resin composition with an interval with respect to the photosensitive film, light is irradiated from a light source disposed on the side of the mask member to subject the photosensitive film to light exposure through the light transmitting sections of the mask member, and exposed portions or unexposed portions of the photosensitive film are removed by development to produce convexes and concaves on the photosensitive film in shapes determined by shapes of the exposed portions or unexposed portions. In the light exposure, light exposure conditions such as distance L between the light source and the mask member, size D of the light source and optical distance T between the mask member and the photosensitive film are controlled so as to control the shapes of the exposed portions or unexposed portions.
