Abstract
The present invention provides photoimageable compositions, processes and articles of manufacture. In particular, the invention provides a process comprising electrophoretically applying a coating layer of a photoimageable composition onto a conductive surface, the composition comprising a material that contains one or more photoacid labile groups. The photoimageable compositions of the invention preferably comprise a photoacid generator, a material that contains one or more acid-clearable functional groups, and a carrier resin that contains one or more functional groups that are, or can be treated to be, at least partially ionized.
