Abstract

1400589 Developing dye images HORIZONS RESEARCH Inc 20 Sept 1972 [22 Sept 1971 (3)] 43600/72 Heading G2C A process for developing a latent image in a photographic material such as disclosed in Specification 1177679 which comprises exposing the material to red light of band width of not more than 50 nm; the band being selected to exclude shorter wavelengths to which the unexposed film is sensitive and longer wavelengths which cause thermal fog. Preferably the red light has a peak value of 730 nm and is provided by a light emitting diode optionally with a transmission filter or by passing the light through a narrow band pass interference filter. As shown, the imagewise exposed film F is exposed to an array of light emitting diodes 22.
