Abstract

1322385 Mosaic photo-conductive material ILFORD Ltd 12 Jan 1972 [9 Dec 1970] 58512/70 Heading G2H After the reproduction of a coloured original by exposing a charged mosaic photo-conductive material to light through a negative of the original, developing the non-light struck areas with white toner and developing the light struck areas by re-charging, uniformly exposing to one complementary colour and developing with dye toner of that complementary colour, the re-charging, exposing and developing steps being repeated for the other complementary colours, the developed material is exposed to the vapour of of dimethylformamide or ethyl alcohol so as to spread each dye toner into the surrounding areas to a controlled extent. A slow curing alkyd resin may be applied to the developed material in a volatile solvent before the vapour treatment.
