Abstract

A presensitized printing plate contains a leuco dye and an organic azide to provide a print-out image when the presensitized plate is exposed to light. Development of the plate may remove the print-out image but provides a relief image which may be dyed or pigmented. The light sensitive unsaturated materials used to provide the relief image include photocrosslinkable unsaturated polymers containing the moiety ##STR1## as part of the polymer backbone.
