ABSTRACT:
An improved method is disclosed for making color filters via electrodeposition or lithographic electrodeposition of a plurality of colored resins onto an electrically conductive substrate. The method comprises the steps of: (a) forming a black-hued pattern on the substrate; (b) dividing the substrate into an intended zone and a conjugate zone, the intended zone being portions of the substrate to be deposited with the colored resins and the conjugate zone being portions of the substrate not to be deposited with the colored resins; (c) forming a permanent insulation film on the conjugate zone of the substrate; and (d) electrodepositing the colored resins onto the intended zone of the substrate. The photosensitive insulation resin is preferably a negative photosensitive resin containing: (i) a resin binder containing a carboxyl (COOH) group; (ii) 1-15 wt %, based on the weight of the resin binder, of a photopolymerization initiator; and (iii) 30-100 wt %, based on the weight of the resin binder, of a photo-reactive monomer or oligomer each containing at least two unsaturated double bonds.
