PROBLEM TO BE SOLVED: To form a high precision phosphor pattern of a uniform shape with high work efficiency and to prevent the deterioration of the surface of a substrate for a plasma display panel by incorporating a polymer binder, a photopolymerizable unsatd. compd., a photo-initiator and a phosphor and specifying the content of a sulfonic acid deriv. SOLUTION: This photosensitive resin compsn. contains a polymer binder, a photopolymerizable unsatd. compd. having an ethylenic unsatd. group, a photo- initiator forming free radicals when irradiated with active light and a phosphor and contains <500 ppm by weight (expressed in terms of elemental sulfur) of a sulfonic acid deriv. The polymer binder is preferably a vinyl copolymer and the photopolymerizable unsatd. compd. may be any of compds. known as photopolymerizable multifunctional monomers. The photo-initiator is, e.g. arom. ketone or N,N'-tetramethyl-4,4'-diaminobenzophenone. The phosphor is not especially limited and an ordinary metal oxide-base phosphor may be used. |
