VERFAHREN ZUR VERWENDUNG VON KURZWELLIGEM UV-LICHT ZUR SELEKTIVEN ENTFERNUNG EINER BESCHICHTUNG VON EINEM SUBSTRAT UND DANACH HERGESTELLTER GEGENSTAND

摘要

A method of selectively removing a functional organic coating from a substrate by exposure of the coating to short wavelength ultraviolet light. The UV light utilized in the invention preferably has a dominant wavelength of from 5 nm to 254 nm. The method is particularly useful for removing selected portions of a hydrophobic coating on a glass substrate for use as an automotive glazing.
