Jared B Mooberry, William C Archie Jr: Blocked photographically useful compounds in photographic compositions, elements and processes employing them. Eastman Kodak Company, Joshua G Levitt, January 12, 1982: US04310612 (17 worldwide citation)

Photographically useful compounds such as photographic reagents and photographic dyes are blocked with a grouping which, under alkaline conditions, is cleaved from the compound by an intramolecular nucleophilic displacement reaction. The compounds are resistant to unblocking under storage conditions ...

William D Devine: Coating by means of a coating hopper with coating slots where the coating composition has a low slot Reynolds number. Eastman Kodak Company, Joshua G Levitt, William T French, Carl F Ruoff, September 1, 1992: US05143758 (14 worldwide citation)

In the hopper coating of liquid compositions on moving webs, as in the coating of photographic layers on film supports, the trapping of solid particles or bubbles in the hopper slots causes line defects or streaks in the coated layers. These defects are avoided or reduced by determining the conditio ...
