ABSTRACT:
A photosensitive resin laminate comprising at least a support, a photosensitive resin layer, a tackiness preventive layer and a cover film successively laminated, said tackiness preventive layer having a water content of not less than 4 wt % under a relative humidity (RH) of 30-80%. During the production of such photosensitive resin laminate, a water content of the tackiness preventive layer of not less than 4% has been achieved by adding a water retention agent to the tackiness preventive layer or allowing presence of water on the cover film (preferably by directly spraying water onto the cover film or placing a water-containing sheet on the cover film), as a result of which the tackiness preventive layer thereof is free of occurrence of wrinkles during any handling step and under any environment.
