Abstract: This invention relates to a class of phthalein 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 3,3disubstituted naphthalides wherein the 3,3 substituents are 8''hydroxy-5''-quinolyl radicals.

Abstract translation: 本发明涉及一种在摄影过程中用作光学过滤剂的酞类指示剂染料，以在入射光的存在下保护选择性曝光的感光材料免于进一步曝光。 这样的染料包括3,3-二取代的苯酞和3,3-二取代的萘，其中3,3个取代基是8'-羟基-5'-喹啉基。
