Cardolite Corporation is pleased to present the 2011 M.T. Harvey Award for innovative commercial advancement in cashew nutshell liquid (CNSL) technology to Dr. Jeffery H. Banning, Principal Scientist and Xerox Fellow in the Consumables Development & Manufacturing Group (CDMG) at Xerox Corporation.
In 2001, Dr. Banning was challenged to develop a new Cyan for use in Xerox’s Phase Change Hot Melt Ink. Dr. Banning’s first approach was to employ Cardolite® NC-510 as an intermediate in making a substituted phthalocyanine dye that would be compatible in the ink base. Cardolite® NC-510 is a 3-n-pentadecylphenol derived from CNSL and has been described by Dr. Banning as “just the kind of molecule I was looking for.” This approach successfully passed all performance requirements. Other phenols were subsequently studied, but none demonstrated sufficient properties to support more extensive testing. A large team of scientists and engineers were involved in bringing this product to commercialization which today continues to be a key dye for Xerox’s hot melt inks. Dr. Banning described this dye, originally coded Cashew Blue, as the most beautiful cyan dye. This project is among Dr. Banning’ several accomplishments that include the invention, development, scale up, and commercialization of many product lines and the publication of over 100 U.S. patents in his 24+ years career.
