Abstract (en)

[origin: EP0357040A1] A heat-developable color photographic material and a method for forming an image using the same. The material comprises a support having thereon a light-sensitive silver halide, a binder, a diffusive reducing agent and a dye donor compound capable of releasing or forming a diffusive dye in correspondence or reverse correspondence with the reaction of reducing the silver ion into silver, wherein said material comprises at least two light-sensitive layers each having a different color sensitivity and at least one layer containing at least one compound represented by formula (I) between the two light-sensitive layers: <CHEM> wherein R<1> and R<2> each represents a hydrogen atom, a halogen atom, or a substituted or unsubstituted alkyl, acylamino, alkoxy, aryloxy, alkylthio, arylthio, sulfonyl, acyl, carbamoyl or sulfamoyl group; or R<1> and R<2> may together form a carbon ring; X represents -CO- or -SO2-; and R<3> represents a substituted or unsubstituted alkyl, aryl, heterocyclic, alkoxy, aryloxy or amino group; provided that the total of the carbon atoms in R<1>, R<2>, and R<3> is 10 or more, and the compound of the formula (I) is substantially insoluble in water.
