Abstract
A composition for the production of an antireflection coating, comprising a condensate obtainable by the condensation of silicon compounds of the general formula RSiX(I) in which the X groups are the same or different and represent hydrolyzable groups or hydroxyl groups, the R groups are the same or different and represent non-hydrolyzable groups, and n is 0, 1, 2, or 3, wherein the composition comprises at least one polymeric agent controlling the rheology and at least one solvent with a boiling point of at least 150° C. The present invention also describes methods for the preparation and use of the present composition. In particular, the composition can be applied by screen printing methods on substrates.
