Definitions

  • a method of producing photographic contrasts coniprising the steps, exposing portions of a light-sensitive system comprising a lyophile support containing a lightsensitive compound selected from the group consisting of o-nitro-mandelonitrile and aromatic diazo compounds to decompose said compound at selected portions of said system, simultaneously contacting said light dccomposition product with a water-soluble mercurous salt and a soluble citrate in. the presence of moisture to form a physically intensifiable contrast, and subsequently physically developing said contrast by applying thereto a developing solution containing a reducible salt of a noble metal and a water-soluble reducing agent.
