Abstract
A process for forming a color image is disclosed. The process involves providing a color light-sensitive photographic material and imagewise exposing the material. The latent images within the exposed material are then developed and subjected to intensification processing. Thereafter, the material is subjected to treatment with a dilute buffer solution having a pH adjusted within the range of 2 to 7. The process allows for the elimination of the washing step conventionally used in processing photographic materials. Furthermore, the process provides color images having a reduced amount of staining and a large intensification factor while utilizing color photographic materials containing an extremely small amount of silver.
Claims17
A process for forming a color image, comprising the steps of:
- providing a light-sensitive silver halide color photographic material;
- imagewise exposing the material in order to form a latent image;
- subjecting the material to color development and intensification processing in order to develop the latent image and form a developed and intensified image, the color development and intensification processing being carried out in a combined developing and intensifying bath containing a compound selected from the group consisting of hydrogen peroxide and a compound capable of releasing hydrogen peroxide and a developing agent, said combined bath not containing substantially any bromide ion or any iodide ion, the combined bath further comprising at least one nitrogen-containing heterocyclic compound;
- and
- treating the material with a non-bleach, non-fix, dilute buffer solution containing a buffer agent and having a pH adjusted within the range of 2 to 7.
