Abstract

1,240,707. Photographic light-sensitive materials. EASTMAN KODAK CO. July 12, 1968 [April 22, 1968], No.7222/71. Heading G2C. A photographic light-sensitive material comprises a support bearing a layer of a polymer having free hydroxy groups and vinyl anthranilate units in which a radiation-sensitive palladium compound has been imbibed or incorporated. The polymer may be copoly (vinyl alcohol-vinyl anthranilate-vinyl succinate). Palladium compounds include palladium oxalate, co-ordination compounds of palladium, e.g. K 2 PdCl 4 , K 2 Pd (oxalate) 2 and Pd(NH 3 ) 4 Cl 2 and complexes of PdCl 2 with organic compounds. After exposure to light the material is physically developed to give a visible image. Physical developers for the material contain a heavy metal salt, e.g. of Ni, Co, Fe, Cu, Cr, Pd, Pt, Ag or Au; a reducing agent for the heavy metal ion, e. g. formaldehyde, water-soluble hypophosphites, hydrosulphites and borohydrides, borane amines and hydrazine; and a complexing agent for the heavy metal ion, e.g. NH 4 Cl, aspartic, malic, citric or glycolic acids, sodium or potassium citrate, glycolate or succinate or potassium sodium tartrate. The developer may also contain a complexing agent for palladium ions such as gluconic acid, saccharic acid and quinic acid and water-soluble salts thereof, and a minor amount of stannous ions may also be present. After exposure, the lightsensitive palladium material may in certain cases be washed to remove unexposed palladium compound and then immersed in the physical developer bath to obtain a visible image. Alternatively the exposed material may be brought into contact with a receiving sheet containing physical developer solution and heated to promote migration of unexposed palladium compound to the receiving sheet where it is developed. The light-sensitive palladium material may be used to prepare lithographic printing plates by developing heavily using an ink-reception heavy metal or to make printed circuits using a non-conductive support and a heavy metal such as Cu, Fe or Ni.
