Photosensitive resin composition for screen printing, photosensitive film, and screen plate
A photosensitive resin composition is prepared by dispersing at least one of a hydrophobic polymer and a mixture of an oil-soluble photopolymerization initiator and a water-insoluble or sparingly water-soluble compound having at least one photoactive, ethylenically unsaturated group in an aqueous solution that contains both a water-soluble polymer and a diazo resin is obtained by condensing a water-soluble salt of an optionally substituted 4-diazodiphenylamine with formaldehyde in the presence of sulfuric acid and phosphoric acid. This photosensitive resin composition gives a photosensitive film having excellent stability over time and a wide exposure latitude. By adding a specific fluorine compound to the photosensitive resin composition, a screen plate has an excellent discharge performance.
