METHOD FOR THE PRODUCTION OF RELIEF COPIES |
摘要 |
A process for producing relief copies wherein the light-hardenable layer of a light-hardenable copying material, which contains a photopolymerizable mixture, a photodimerizable polymeric compound or a diazonium salt polycondensation product, is exposed to a light image, the exposed layer is subjected to a brief ultrasonic treatment, and the unexposed areas of the layer are thereafter washed away by means of a developer. As a result of the ultrasonic treatment, shorter exposure times may be used and better in-depth hardening of the layer may be achieved. |
