The ion reacts with the ionophore in the water immiscible material, releasing a proton which reacts with the pH indicator generating a color change which is representative of the ion to be measured. The stabilizing compound stabilizes this change. Also described are compositions including the three recited elements, and various new compounds useful as the stabilizer.Type: GrantFiled: May 10, 1991Date of Patent: June 1, 1993Assignee: Boehringer Mannheim GmbHInventors: Walter Rittersdorf, Werner Guethlein, Detlef Thym, Peter Vogel

Patent number: 4621156Abstract: Optical filter agents and photographic products and processes using same are disclosed. The optical filter agents are pH-sensitive hydrazone compounds conforming to the following structural formula: ##STR1## where R is any group which can provide a double bond for conjugation with the ##STR2## portion of the compound to provide light-absorbing capability or color for the agent at a pH above its pKa, X is a substituent of R providing at least one electron-withdrawing group and each R' can be defined as any substituent that does not impair the light-absorbing capacity of the compound at a pH above the pKa thereof. The pH-sensitive optical filter agents have a highly colored light-absorbing form at a pH above the pKa and are substantially non-absorbing at a pH below the pKa. The pH-sensitive optical filter agents are useful in photographic film units and processes for the protection of photoexposed photosensitive elements against the occurrence of fogging during in-light development.Type: GrantFiled: October 8, 1981Date of Patent: November 4, 1986Assignee: Polaroid CorporationInventors: Derek H.
