<P>PROBLEM TO BE SOLVED: To provide a light shielding film, which has thin thickness, causes little internal reflection, and causes no bleeding of a dye, for optical elements. <P>SOLUTION: The light shielding film for optical elements includes at least an epoxy resin, an amine curing agent, and a dye. The light shielding film has a mean extinction coefficient of 0.04 or more. One molecule of the dye has two or more amino groups. Preferably a ratio (minimum value/maximum value) of a minimum value to a maximum value of transmittance of the light shielding film to light with a wavelength of 400-700 nm is 0.7 or more. <P>COPYRIGHT: (C)2011,JPO&INPIT |
