Abstract
An optical filter comprises a transparent support and a filter layer. The filter layer contains a dye and a binder polymer. The dye is a methine dye in an aggregated form. The transparent support, the filter layer or an optional layer further contains a specific ultraviolet absorbing agent represented by the formula (I), (II), or (III).
