Abstract
A method of stabilizing organic substrate materials having an absorption maximum in the wavelength region of about 300 nm to about 800 nm to light which comprises making coexist with the organic substrate at least one metal complex salt represented by the following general formula (I): ##STR1## wherein Cat represents a divalent or a monovalent cation, and n is 1 or 2. A photographic material thus stabilized is also disclosed.
Claims16
An element stabilized against the action of light comprising the combination of
- (a) a photographically useful dye having an absorption maximum in the wavelength range between about 300 nm and about 800 nm, and
- (b) at least one metal complex salt represented by the general formula (I):
- ##STR16## wherein n is 1 or 2 and Cat represents a divalent cation where n is 2 or a monovalent cation where n is 1.
A color photographic material comprising at least one layer containing a photographic dye image, said dye of said dye image having an absorption maximum in the wavelength range between about 300 nm and about 800 nm, wherein said layer or an adjacent layer thereto contains at least one metal complex salt represented by the general formula (I) ##STR19## wherein n is 1 or 2 and Cat represents a divalent cation where n is 2 or a monovalent cation where n is 1, stabilizing said dye to the action of light.
