Abstract
1,042,479. Developing photographic silver halide material. ILFORD Ltd. Jan. 29,1965 [Feb. 3, 1964], No. 4540/64. Heading G2C. An exposed gelatine silver iodobromide photographic material, particularly X-ray film, is developed by treatment at 65 to 80‹F for a period not exceeding 100 seconds with a developer composition containing hydroquinone and a compound of the formula:- wherein R 1 is hydrogen or alkyl of 1 to 4 carbon atoms, R 2 is alkyl or alkoxy of 1 to 4 carbon atoms or benzyloxy or R 1 and R 2 together form a tetramethylene group, the said photographic material being such that it will achieve its maximum speed within the period of treatment.
