Method for stabilizing organic substrate materials including photographic dye images against the action of light and a photographic material so stabilized

摘要

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.
