Production method of screen printing plate and screen printing plate using the same and photosensitive resin composition

摘要

PROBLEM TO BE SOLVED: To obtain a photosensitive resin composition excellent in water and organic solvent resistances and printing resistance and to produce a screen printing plate using the composition. SOLUTION: A dispersoid comprising a water-insoluble or slightly water-soluble thermally crosslinkable compound is dispersed in a dispersion medium comprising a water-soluble saponified body of a vinyl acetate polymer containing a styrylpyridinium group or a styrylquinolium group and having =50 mol% saponification degree to obtain the objective photosensitive resin composition. The objective screen printing plate has a resin layer comprising the pbotosensitive resin composition in which water-insoluble particles, hydrophobic polymer particles and the saponified body have been crosslinked and integrated. The photosensitive resin composition is applied to a screen mesh, dried, exposed, developed and heated or irradiated with thermic rays to produce the screen printing plate.
