Abstract
1281131 Photographic colour reversal processing EASTMAN KODAK CO 24 Sept 1970 [24 Sept 1969] 45555/70 Heading G2C An exposed photographic multi-colour silver halide material is reversal processed using as a first (non-colour) developer, a developer of pH 9À1 to 9À6 containing at least 1À5 g/l of hydroquinone and in addition at least 0À5 g/l of 1-phenyl-3-pyrazolidone or at least 1 g/l of a 4-substituted-1 -phenyl-3-pyrazolidone. The first development is then followed by stop, wash, colour development, stop, wash, bleach, fix and wash steps to give the final reversed colour image. The processing may be conducted at temperatures of 38‹ to 52‹C. or higher. The colour material used may or may not contain colour couplers.
