摘要： This invention relates to a class of indicator dyes useful as optical filter agents in photographic processes to protect a selectively exposed photosensitive material from further exposure during processing in the presence of incident light. Such dyes comprise 3,3-disubstituted phthalides and 3,3-disubstituted naphthalides wherein one of the 3,3-substituents is an indol-3-yl radical substituted with hydrogen on the heterocyclic N atom and the other of said 3,3 substituents is a p-hydroxycarbocyclic aryl radical selected from a 4'-hydroxy-1'-phenyl radical and a 4'-hydroxy-1'-naphthyl radical.
