Color image stabilizing method to provide color fastness to light

Abstract

Abstract PURPOSE: To enhance the color fastness of an anilino type magenta color image to light by adding one or more kinds of specified complexes and one or more kinds of specified light fading preventives to a layer for retaining the image. CONSTITUTION: To a layer for retaining an anilino type magenta color image are added one or more kinds of complexes represented by formulae IWIV (where each of R 1 WR 4 is H, halogen, CN, alkyl, aryl, a heterocyclic ring or the like bonding to C on the benzene ring directly or through a divalent combining group, each of R 5 , R 8 and R 9 is H, alkyl or aryl, R 6 is H, alkyl, aryl or OH, R 7 is alkyl or aryl, R 7 and R 8 , and R 8 and R 9 may bond to each other to form a 5- or 8-membered ring, and M is Cu, Co, Ni, Pd or Pt) and one or more kinds of light fading preventives represented by formulae VWVII (where R 10 is H, alkyl or the like, A is nonmetallic atoms required to form a 5- or 6-membered ring, each of R 11 WR 13 is H, alkyl or the like, R 14 is 1W22C optionally branched alkyl or the like, R 15 is H, 1W22C alkyl or the like, R 16 is H, halogen or the like, R 17 is 3W22C alkyl or the like, and R 18 is 1W22C optionally branched alkyl or the like).
