Abstract
A light sensitive reprographic paper which is protected against deterioration caused by rough handling. The paper comprises a paper base having first and second surfaces, and a coating on the first surface comprising a light sensitive diazo-containing composition which develops by reaction with ammonia gas. The paper is adapted for development by exposure of one of the first and second surfaces to ammonia gas. A substantially transparent, flexible, polymeric sheet is permanently laminated to the paper surface which is not to be exposed to the gas.
