A method of stabilizing organic substrate materials against the action of light is disclosed wherein at least one compound represented by the following general formula (I) is made to coexist with the organic substrate material ##STR1## wherein M represents a Cu, Co, Ni, Pd or Pt atom, R.sup.1 represents an alkyl or an aryl group, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 may be the same or different and each represents a hydrogen atom, a halogen atom, an alkyl group or an aryl group. Alternatively, R.sup.2 and R.sup.3, R.sup.3 and R.sup.4 or R.sup.4 and R.sup.5 may combine together to form a 6-membered ring. A photographic material containing the above compound is also disclosed.
A method of stabilizing a photographically useful organic substrate material having an absorption peak between about 300 and about 800 nm in wavelength, said organic substrate material being selected from the group consisting of anthraquinone dyes, quinoneimine dyes, azo dyes, methine dyes, polymethine dyes, indamine dyes, indophenol dyes, indigoid dyes, carbonium dyes and formazane dyes, against the action of light which comprises making coexist with said substrate material at least one compound represented by the following general formula (I) ##STR14## wherein M represents a Cu, Co, Ni, Pd or Pt atom;
A color photographic material comprising at least one layer containing a photographic dye image wherein said layer or an adjacent layer contains a compound of the formula (I):
A diffusion transfer color photographic material comprising a photosensitive element and an image-receiving element, said image-receiving element, comprising a support having thereon a mordanting layer containing a complex of the formula (I):
