Title: PHOTOGRAPHIC FILM DEVELOPER

Abstract

S>An improved photographic developer is presented having very high energy development fine grain characteristics and a long shelf life. These characteristics are obtained by the use of aminoacetic acid in the developer, the other constituents of which are: sodium sulfite, hydroquinone, sodiunn borate, boric acid and potassium bromide, 1-phenyl-3-pyrazolidone.
