| description | PROBLEM TO BE SOLVED: To provide an optical filter capable of sufficiently absorbing side bands of light emission spectrum of a red phosphor and satisfactorily maintaining initial filter performance over a long period of time even under the loading of heat history, and to provide an anti-reflection film having the characteristics of the optical filter. SOLUTION: The optical filter made by laminating a filter layer containing pigment and polymer binder on a transparent substrate contains a condensed multi-ring type pigment which is surface-treated with a pigment sulfonic acid derivative in the filter layer and has only one absorption peak in the wavelength region of 551-600 nm. The anti-reflection film made by laminating a filter layer containing pigment and polymer binder, a transparent substrate and a low refractive index layer which has a refractive index lower than that of the transparent substrate in order contains the condensed multi-ring type pigment which is surface-treated with a pigment sulfonic acid derivative in the filter layer and has only one absorption peak in the wavelength region of 551-600 nm.
