<p>PURPOSE:To obtain the subject ink having high color purity and giving a color filter having high reliability with a simple process by dispersing a color pigment in a specific photosensitive resin composition and a polymer compound containing a specific amount of a specific constituent unit containing pyrrolidone group. CONSTITUTION:The objective photosetting ink suitable as a printing material for photoengraving is produced by dispersing (A) a color pigment such as organic pigment in a photosensitive resin composition produced by dissolving (B) a polymer compound produced by the (co)polymerization of a (meth) acryloxyalkyl-2-pyrrolidone, etc., containing >=20mol% of the constituent unit of formula (R1 is H, CH3 or C2H5; X is NH or O; m is 1-5) and (C) an azide compound such as 4,4'-diazidochalcone as a photo-crosslinking agent in a solvent.</p> |
