A photoimageable composition for preparing a polymeric binder having one or more of monomeric unit copolymers, a photosensitive compound, and one or more organometallic compounds is provided. The copolymer comprises one or more hydroxyl or carboxyl functional groups which, when cured, react with the organometallic compound to form a crosslinked network. The photoimageable composition may be particularly suitable for forming a pixel defining layer of an electronic device such as an organic light emitting diode. In particular, the photoimageable composition according to an embodiment of the present invention is insoluble in the developer prior to exposure to radiation, soluble in the developer upon exposure to radiation, and has a relatively high glass transition temperature (Tg), It is suitable for forming a pixel defining layer. |
