Photochemistry, History and Commercial Applications of Hexaarylbiimidazoles

All about HABIs


  • Rolf Dessauer, Greenville, Delaware, USA

The objective of this book is to acquaint the reader with a novel class of photochemical oxidants and polymerization initiators that have become widely accepted in industry. As most of the work with these materials is reported in the patent literature, an effort has been made to study this area of scientific activity, as well as present a thorough review of the journal publications. Photochemistry, History and Commercial Applications of HABIs also presents new technologies such as waveguides, holography along with some more traditional applications (i.e. filters, litho plates, and photoresists).

All disc-based content for this title is now available on the Web.

For practicing photochemists, professors who are interested in relating research to product development and scientists who may have some interest in learning about patents
