A non-reversal imaging process wherein a recording element having a layer of a photosensitive composition which upon light exposure produces light-generated nuclei of a metal more noble than silver, i.e. Pd, Pt, Au, is exposed to an image. The exposed element is treated with a solution of trimethylamine borane, triethylamine borane, t-butylamine borane, pyridine borane, morpholine borane, sodium borohydride, lithium aluminum hydride or hydrazine to generate in the unexposed areas of the layer chemically reduced metal nuclei which are more highly catalytic to the electroless deposition of a non-noble metal than the light generated nuclei. Non-noble metal is then electrolessly plated selectively on the chemically reduced nuclei to produce a non-reversed image.
