Abstract
Abstract A novel copper (II) complex having the formula: [CuL.sub.n ](BAr.sub.4).sub.2, wherein L is a monodentate or polydentate ligand, Ar is aryl containing from 6 to 12 carbon atoms, and n is an integer of 2 or 4, is employed as an actinic radiation-sensitive component in an imaging process comprising imagewise-exposing a support carrying the copper (II) complex to actinic radiation and developing an image by direct printout or chemical or physical development. The complex has improved photographic speed and may be handled in room light prior to development.
