Summary:A photographic process wherein a relief image is formed by means of a photographic material comprising in a recording layer a photosensitive dispersed phase in the form of discrete particles of an intimate mixture of N-vinylcarbazole and carbon tetrabromide in a hardenable hydrophilic colloid medium. The process includes a negative and a positive working mode. Unhardened colloid portions are removed by wash-off. Gelatin is used preferably as hardenable colloid.
