Abstract

A process for recording laser radiation is disclosed. A photosensitive material comprising a copying coating and a carrier is exposed to visible laser light having no ultra-violet component and is then developed. The process is characterised by the use of a negative working diazonium compound and a binder which together form the copying coating. The diazonium compound comprises more than 25 percent of the total coating weight. The relatively high concentration of diazonium compounds causes an increased photosensitivity when the material is exposed to laser light from which virtually all the ultra-violet in the range of sensitivity of the diazonium compound has boon excluded loading to increased exposure speeds or of shortened exposure times.
