Abstract
A photothermographic imaging material including an organic silver salt, a binder, a reducing agent, coupler and a main developing agent which forms coloring images by reacting with the coupler, those which are on a support wherein the reducing agent comprises a compound represented by the following Formula (1), the coupler is a compound represented by the following Formula (CP1) and sum of maximum density of colorant images at maximum absorption wavelength formed by the coupler and the main developing agent is 0.01 or more and 0.50 or less
Claims11
A photothermographic imaging material comprising a organic silver salt, a silver halide, a binder, a reducing agent, a cyan leuco dye, and a yellow coloring leuco dye represented by the following Formula (YA);
- and
- wherein the R11 represents a substituted or unsubstituted alkyl group, the R12 represents hydrogen atom or substituted or unsubstituted alkyl or acylamino groups, the R11 and the R12 are not 2-hydroxyphenylmethyl group, the R13 represents hydrogen atom or substituted or unsubstituted alkyl group, and the R14 represents a group capable of being substituent on a benzene ring;
- and
- wherein the reducing agent comprises a compound represented by the following Formula (1);
- and
- wherein the X1 represents chalcogen atom or —CHR1, the R1 represents hydrogen, halogen, alkyl group, alkenyl group, aryl group or heterocyclic group, and the R2 represents alkyl group, the two R2s can be either same or different, and at least one of them is secondary or tertiary alkyl group, the R3 represents hydrogen atom or a group which can be a substituent on a benzene ring, the R4 represents a group which can be a substituent on a benzene ring, the m and the n represent integer of 0 to 2 respectively.
