Radiation-induced reaction of sulfonamide-containing polymers in the film state for color imaging

摘要

A polysulfonamide and copolymers consisting of sulfonamides and amides underwent Fries rearrangement and scission, forming amino groups upon EB irradiation. The EB irradiation of these films with a dose of 500 mu C.cm(-2), followed by the color forming reaction provided the color imaging of line/space patterns with a resolution of 300 nm.
