Abstract

Abstract The light stability of organic dyes is improved by the presence of at least one of the complexes represented by general formula (I) or (II) ##STR1## wherein M represents a Cu, Co, Ni, Pd or Pt atom; R 1 and R 4 , which may be the same or different, each represents an alkyl group or an aryl group; R 2 and R 3 , which may be the same or different, each represents a hydrogen atom, an alkyl group or an aryl group; or R 1 and R 2 , and R 3 and R 4 may combine to represent a non-metallic atomic group necessary to form a 6-membered ring; and Z represents a non-metallic atomic group necessary to form a 5-membered ring, 6-membered ring, 8-membered ring, or 10-membered ring.
