    • Disclosed is a thermally processed image recording material having an image-forming layer that contains a non-photosensitive silver salt of an organic acid, a reducing agent for silver ions and a binder on a support, wherein the binder is coated as a dispersion of polymer microparticles having a core/shell structure, glass transition temperature of shell part of the core/shell structure is higher than glass transition temperature of core part, and the binder shows a minimum film-forming temperature of 30° C. or lower. According to the present invention, there is provided a thermally processed image recording material that provides improved image storability after heat development, i.e., improved coloration of white portions when the material is left at a high temperature, and has a transparent coated film with low haze that is also excellent in brittleness.
