Estimating the term…
A thermographic recording material, thermally developable under substantially water-free conditions, comprising a support and a thermosensitive element, the thermosensitive element being provided with a protective layer and the thermosensitive element containing a substantially light-insensitive silver salt of an organic carboxylic acid, a reducing agent therefor in thermal working relationship therewith and a binder, wherein the protective layer contains at least one proteinaceous binder and non-opacifying inorganic particles with a weight averaged diameter of less than 1μm in a concentration of between 5 and 70% by weight with respect to the weight of the protective layer.
A thermographic recording material, thermally developable under substantially water-free conditions, comprising a support and a thermosensitive element, said thermosensitive element being provided with a protective layer and said thermosensitive element containing a substantially light-insensitive silver salt of an a organic carboxylic acid, a reducing agent therefor in thermal working relationship therewith and a binder, wherein said protective layer consists essentially of at least one proteinaceous binder and non-opacifying inorganic particles with a weight averaged diameter of less than 1μm in a concentration of between 5 and 70% by weight with respect to the weight of said protective layer, and wherein said proteinaceous binders in said protective layer together contain less than 300 ppm of halide ion.
Thermographic recording material according to claim 8, wherein said halide ion is a chloride ion.
Thermographic recording material according to claim 13, wherein said gelatin is at least 20% in the gel-form.
