ABSTRACT:
A method of stabilizing an organic substrate material having an absorption maximum in the wavelength region of about 300 nm to about 800 nm to light without detracting from the color hue and the purity of the organic substrate material, which comprises making at least one metal complex salt represented by the following formula (I) coexist with the organic substrate material: ##STR1## wherein M represents a Cu, Co, Ni, Pd or Pt atom; R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.6, R.sup.7, R.sup.8 and R.sup.9 each represents a hydrogen atom, a halogen atom or a cyano group, or an alkyl group, an aryl group, a cycloalkyl group or a heterocyclic ring which may be attached directly to the carbon atom in the respective ring or through a divalent coupling group, or R.sup.1 and R.sup.2, R.sup.2 and R.sup.3, R.sup.3 and R.sup.4, R.sup.6 and R.sup.7, R.sup.7 and R.sup.8, or R.sup.8 and R.sup.9 may combine to form the non-metal atoms necessary to complete a 6-membered ring; R.sup.5 represents a hydrogen atom, an alkyl group or an aryl group; and X represents a chlorine atom, a bromine atom or an iodine atom.
