Abstract
A heat-developable light-sensitive material is described, which contains fine particles of a substantially water-insoluble base precursor incorporated in a binder. This light-sensitive material is superior in stability with the passage of time and the changes on the photographic characteristics such as maximum density, minimum density and sensitivity are less during the storage thereof.
