Anti-reflection coating composition and process for preparing the same
The present invention relates to an anti-reflection coating composition containing hollow particles, an adhesive, and a hydrophobic organic solvent, wherein the weight ratio of the hollow particles to the solids content of the adhesive is in the range of 1:2 to 1:20. The present invention also provides a method for producing the anti-reflection coating composition.
1. An anti-reflection coating composition, comprising hollow particles, an adhesive and a hydrophobic organic solvent, wherein the hollow particles are dispersed in the adhesive and are chemically bonded with the adhesive, and the weight ratio of the hollow particles to the solid content of the adhesive is in the range of 1:2 to 1:20, wherein the hollow particles are inorganic oxide particles containing an element selected from the group consisting of silicon, titanium, zirconium and a combination thereof; and
wherein the adhesive is a polyacrylic resin modified by a silicon-containing compound or a polysiloxane resin, and the adhesive has a hydrophobic group selected from the group consisting of phenyl, benzyl, alkyl and a combination thereof and has a group —Si(OR 1 ) n (R 2 ) 3-n , wherein n is an integer of 2 or 3, R 1 is each independently H or C 1-4 alkyl, and R 2 is each independently H or C 1-4 alkyl, wherein the ratio of the weight of the hydrophobic organic solvent to the total weight of the hollow particles and the solid content of the adhesive is in the range of 1.5:1 to 40:1.
