Abstract
A light-sensitive composition for the preparation of printing plates and photoresists is described, which comprises as the light-sensitive compound a diazonium salt polycondensation product and as the binding agent a branched polyurethane resin which contains no terminal isocyanate groups and the terminal units of which are at least partially derived from dihydroxy compounds. The printing plates produced with this light-sensitive composition are easily developable with aqueous developer solutions and yield long press runs.
