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 phydroxy carbocyclic aryl radicals wherein one or both of the radicals possess a -CH2-NRR'' group ortho to the p-hydroxy group and the -CH2-NRR'' group(s) is capable of rendering the indicator dye substantially non-diffusible in aqueous solution.
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个取代基是对羟基碳环芳基，其中一个或两个基团具有邻羟基的-CH 2 -NRR'基团 基团和-CH 2 -NRR'基团能够使指示剂染料在水溶液中基本上不扩散。

Abstract: THIS INVENTION RELATES TO PHOTOGRAPHY, AND MORE PARTICULARLY, IT RELATES TO THE USE OF MIXED PHENOL AND MIXED NAPHTHOL PHTHALEINS AS OPTICAL FILTER AGENTS TO PROTECT A SELECTIVELY EXPOSED PHOTOSENSITIVE MATERIAL FROM POSTEXPOSURE FOGGING IN PHOTOGRAPHIC PROCESS WHERE DEVELOPMENT OF THE PHOTOSENSITIVE MATERIAL IS CONDUCTED IN THE PRESENCE OF EXTRANEOUS INCIDENT LIGHT. THIS CLASS OF INDICATOR DYES COMPRISES 3,3-DISUBSTITUTED PHTHALIDES AND 3,3DISUBSTITUTED NAPHTHALIDES WHEREIN ONE OF THE 3,3 SUBSTITUENTS IS A P-HYDROXYPHENYL OR A P-HYDROXYNAPTHYL RADICAL AND THE OTHER IS A PHENYL RADICAL OTHER THAN PHYDROXYPHENYL. AT A FIRST PH IN ALKALINE SOLUTION THE ABOVE-NOTED DYES HAVE A HIGHLY COLORED, LIGHT-ABSORBING FORM CAPABLE OF ABSORBING RADIATION WITHIN A PREDETERMINED WAVELENGTH RANGE IN THE SHORTER WAVELENGTH REGION OF THE VISIBLE SPECTRUM AND AT A SECOND LESS ALKALINE PH HAVE A COLORLESS FORM THAT AIIS SUBSTANTIALLY NON-LIGHT-ABSORBING IN THE VISIBLE SPECTRUM. BY SELECTING A DYE FROM THIS CLASS WHICH IS IN ITS LIGHT-ABSORBING FORM AT THE PH AT WHICH DEVELOPMENT IS PERFORMED, PROTECTION OF THE EXPOSED PHOTOSENSITIVE MATERIAL FROM RADIATION ACTINIC THERETO IS OFORDED WITHIN THE WAVELENGTH RANGE ABSORBED BY THE DYE AND SUBSEQUENT TO AT LEAST THE INITIAL STAGES OF DEVELEPOMENT, THE DYE MAY BE RENDERED SUBSTANTIALLY COLORLESS BY ADJUSTING THE PH TO PERMIT VIEWING OF THE FINAL IMAGE.
