PURPOSE:To obtain an infrared image high in density and low in fogging by transferring a dye image on the surface of an image receiving material and laminating the laminating material containing a specified metal source. CONSTITUTION:The laminating material to be laminated on the image receiving layer formed on a support and having the dye image transferred contains at least one of the compounds represented by formula I or II in which M is a transition metal ion; each of X1 - X3 is a ligand coordinated by the metal ion and forming a complex; R1 is alkyl or aryl; (l) is 1, 2, or 3; (m) is 0, 1, or 2; (n) is 0 or 1; p is 1 or 2; and each of R2 - R5 is alkyl, cyano, or the like, thus permitting the laminating material to be used in combination of photographic elements capable of forming an image high in density in a short time and low in fogging and reading by using wavelengths longer than 750nm. |
