  Abstract
 

Color filter coatings are applied in a multi-step process. In each step of the process the requirements to the coating changes. The color resist contains organic solvents, in which it has to have an excellent solubility when it is applied on the glass panel. But it also must have a good water-solubility as in the developing step later on in the application process when a part of the dried, non-cured coating is removed with an aqueous solution in order to create the pixel pattern of the display.

 To achieve these different solubility properties of the color resist the selection of the wetting and dispersing additive plays an important role. The presentation will discuss different strategies how to influence the solubility properties of the color resist with wetting and dispersing additives.

   
  Biography
  Bernd Göbelt, born in Stuttgart, Germany, studied chemistry at the universities in Stuttgart and Kaiserslautern. In 1999 he received his Ph.D. degree for his work in the area of organic and polymer chemistry from the university of Heidelberg. In 1999/2000 he undertook postdoctoral research at the Carnegie Mellon University with Prof. K. Matyjaszewski on atom transfer radical polymerisation. In 2001 he joined Byk-Chemie. He works mainly on the development of wetting and dispersing additives and controlled radical polymerization technologies.
