Publication number: 20090280245Abstract: A printing or coating composition has a non-volatile liquid vehicle carrying a conductive polymer to be deposited on a substrate and is cleavable by heat or acidification without decomposition of said material, cleavage of said vehicle producing decomposition products that are more volatile than said vehicle and which can be evaporated to dry the composition. Suitably, that vehicle is a carbonic acid diester or a malonic acid diester, e.g. of the formula: wherein R2 is an organic substituent such that R2—OH is a volatile alcohol; R1 is an aliphatic or aromatic substituent of more than three carbon atoms such that is volatile; and R3 is C1-3 alkyl.Type: ApplicationFiled: April 13, 2007Publication date: November 12, 2009Applicant: The Technical University of DenmarkInventors: Frederik Krebs, Mikkel Joergensen
