PHOTOSENSITIVE RESIN COMPOSITION FOR SCREEN PLATE MAKING, PHOTOSENSITIVE FILM AND SCREEN PRINTING PLATE FORMED BY USING THE SAME

摘要

PURPOSE:To obtain a screen printing plate having good printability, solvent resistance, water resistance and printing resistance, to obviate the generation of the printing plate by blurring and infiltrating of ink to the rear side at the time of printing, to enable good printing of ultra-fine lines and good printing of a rugged surface and to improve the life of the printing plate. CONSTITUTION:This photosensitive resin compsn. for screen plate making contains at least (A) a fluorine having an ethylenic unsatd. bond or fluorine compd. having the ethylenic unsatd. bond and compd. having another ethylenic unsatd. bond, (B) a photopolymn. initiator and (C) a polyvinyl alcohol and/or water dispersible polymer. The photosensitive film is formed by drying the compsn. on a plastic film and drying the coating and this screen printing plate for plate making is formed by using the film.
