Abstract (en)

[origin: EP0538947A1] The preparation of x-ray materials, especially suitable for non-destructive testing applications, is described. The emulsion layers of said material are comprising silver halide emulsion grains containing at least 75 mole % of silver chloride and less than 25 mole % of silver bromide and are characterised by a ratio between the amount of gelatin and the amount of silver halide, being expressed as the equivalent amount of silver nitrate, of less than 0.6. Hardening of said material is performed in such a way that the amount of demineralised water of 25 DEG C absorbed in 3 minutes is less than 2.5 g per gram of gelatin present in said material. A rapid processing system is available with a total processing time of less than 3 minutes with a developer and fixer being substantially free from hardening agents and the fixer being substantially free from ammonium ions.
