Abstract:
A process for forming a phosphor pattern for a field emission display panel, comprising the steps of:(I) forming (A) a photosensitive resin composition layer containing a phosphor on a substrate onto which a conductive layer was previously applied, wherein the step (I) is: (Ibâ€²) a step of placing a photosensitive element having (B) a filling layer on a support film and (A) the photosensitive resin composition layer containing the phosphor thereon on the substrate onto which the conductive layer was previously applied so as to contact (A) the photosensitive resin composition layer containing the phosphor with the substrate onto which the conductive layer was previously applied, and applying pressure to (B) the filling layer to laminate (A) the photosensitive resin composition layer containing the phosphor and (B) the filling layer on the substrate onto which the conductive layer was previously applied, and (Ic) a step of removing (B) the filling layer; (II) selectively irradiating active light to (A) the photosensitive resin composition layer containing the phosphor, for forming a pattern; (III) selectively removing (A) the photosensitive resin composition layer containing the phosphor to which active light has been selectively irradiated by development to form the pattern; and (IV) calcining the pattern to remove an unnecessary portion to form the phosphor pattern, wherein (A) said photosensitive resin composition layer containing the phosphor contains: (a) a polymer having a film-forming property, (b) a photopolymerizable unsaturated compound having an ethylenically unsaturated group, (c) a photoinitiator forming a free radical by irradiation of active light, and (d) the phosphor.
