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 C.sub.20 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.
