International Classification:

B01D 1504

US Classification:

210686

Abstract:

The invention is for a process of removing dissolved heavy metal cation contaminants from an organic solution. The process of the invention involves providing a mixture of a chelating ion exchange resin modified by removal of sodium ions therefrom and an anion exchange resin and contacting said organic solution with said exchange resins for a time sufficient to remove ionic metal impurities and acids. The invention is useful for removal of ionic contaminants from organic solutions requiring high purity.

Abstract:

A photoimageable composition for preparing a polymeric binder having of one or more of monomer unit copolymers, a photoactive compound, and one or more organometallic compounds is provided. The copolymers include one or more hydroxyl or carboxyl functional groups that react with the organometallic compound to form a crosslinked network upon curing. The photoimageable compositions may be particularly useful in forming a pixel-defining layer of an electronic device. such as an organic light emitting diode. In particular, photoimageable compositions in accordance with embodiments of the present invention are insoluble in the developer prior to exposure to radiation, soluble in the developer following radiation exposure, and have relatively high glass transition temperatures (T) making them useful in forming a pixel-defining layer.
