ABSTRACT:
Recording materials and a method of manufacturing said materials by coating hydrophilic colloidal layer compositions on a support by slide-hopper or curtain-coating techniques, followed by drying, said materials comprising a support and one or more light-sensitive and/or heat-sensitive layer(s) having a hydrophilic colloidal coating composition comprising no gelatin(in the case of (photo)thermographic materials) or gelatin in low amounts in order to provide a ratio by weight of gelatin to silver halide expressed as an equivalent amount of silver nitrate in the range from 0.05 to 0.4 (in the case of a light-sensitive silver halide photographic material) and thickening agents composed of synthetic clay and anionic macromolecular polyelectrolytes and wherein said synthetic clay is present in an amount of at least 85% by weight versus a total amount of thickening agents.
