Abstract (en)
A recording material for producing high contrast images comprising at least one thermosensitive element, comprising a layer comprising a substantially light-insensitive organic silver salt in at least one binder and in thermal working relationship therewith an organic reducing agent therefor, on a support, characterized in that the recording material is light-insensitive and the layer contains colloidal particles comprising silicon dioxide at a coating weight given by expression (1): <MATH> wherein B represents the total weight of all binders in the layer, AGOS represents the total weight of organic silver salt in the layer and S represents the weight of the colloidal particles in the layer; and wherein a protective layer is optionally applied to the thermosensitive element being thereby an outermost layer of the recording material.
