Abstract
An image-forming method is described using a light-sensitive material comprising a support and a light-sensitive layer on the support, said light-sensitive layer containing an o-quinonediazide compound as a first component and a basic carbonium dye as a second component; according to this method images can be obtained both by positive working and negative working techniques. Furthermore, images which are free from yellow light fogging can be obtained by use of a laser beam.
