A negative photosensitive resin composition comprising an alkali-soluble photosensitive resin (A) having acidic groups and having at least three ethylenic double bonds per molecule, an ink repellent (B) made of a polymer having polymerized units (b1) having a C20 or lower alkyl group in which at least one of its hydrogen atoms is substituted by a fluorine atom (provided that the alkyl group may contain etheric oxygen), and polymerized units (b2) having an ethylenic double bond, and a photopolymerization initiator (C), wherein the fluorine content in the ink repellent (B) is from 5 to 25 mass %, and the proportion of the ink repellent (B) is from 0.01 to 20 mass %, based on the total solid content of the negative photosensitive resin composition. The negative photosensitive resin composition of the present invention is excellent in adhesion to a substrate, ink repellency and durability thereof and further excellent in alkali solubility and developability.
A process for producing barrier ribs for a pixel pattern, comprising applying to a substrate a negative photosensitive resin composition comprising an alkali-soluble photosensitive resin (A) having acidic groups and having at least three ethylenic double bonds per molecule, an ink repellent (B) made of a polymer having polymerized units (b1) having a C20 or lower alkyl group in which at least one of its hydrogen atoms is substituted by a fluorine atom (provided that the alkyl group may contain etheric oxygen), and polymerized units (b2) having an ethylenic double bond, and a photopolymerization initiator (C), wherein the fluorine content in the ink repellent (B) is from 5 to 25 mass %, and the proportion of the ink repellent (B) is from 0.01 to 20 mass %, based on the total solid content of the negative photosensitive resin composition and producing barrier ribs therefrom.
