Color filter arrays containing one or more colors for liquid crystal displays and other optoelectronic devices are made by using a laser to ablate portions of a coating on either a colored or transparent substrate. Color filter materials are placed into the ablated openings and cured. The number of laser ablated openings in the coated substrate varies, depending on the quantity and types of colors desired.

Positive working polyamic acid photoresist compositions are disclosed having improved high resolution upon image development and exhibiting stable photosensitivity and superior dielectric performance. The compositions comprise polyamic acid condensation products of an aromatic dianhydride and an aromatic di-primary amine wherein a percentage of the diamine comprises special dissolution inhibiting monomers. The compositions may be further improved by the presence of particular supplemental additives.

Filters suitable for microelectronic uses and the like may be prepared directly on substrates either as monolithically integrated filters or as hybrid filters using a soluble dye material in a resin. The resin may be applied to microelectronic substrates and patterned by conventional microphotolithographic processes.
