Abstract

Sensitivity, adjustable to photography or contact printing can be obtained in positive or negative, by means of a composite product comprising support, hydrophilic layer and three additional layers of which the second is photographically inactive, preferably based on gelatine cellulose nitrate, tanned gelatine and sodium silicate, untanned gelatine, tanned gelatine and sodium silicate, untanned gelatine, tanned gelatine and polyacrylamide or polyvinyl acetate, binds the other two and dissolves in the organic solvents used for stripping the photosensitive polymer. The lower layer contains a photosensitive polymer, pref. polycarbonate, soluble in organic solvent and suitable for use in presensitised plates. The upper layer contains photosensitive Ag-halides emulsion.
