ABSTRACT:
Disclosed is a method for controlling edge fusion in a laminate of an aqueous developable photoresist composition sandwiched between a film support and a protective cover sheet comprising maintaining the relative humidity below about 20% in the environment surrounding the laminate, preferentially achieved by packaging the photoresist with a desiccant in a moisture proof container.
