Top coating composition

Abstract

The present invention relates to a top coating composition comprising polymer (A), surfactant (B) and solvent (S). The polymer (A) comprises a side chain comprising a fused aromatic ring. The surfactant (B) comprises an aliphatic hydrocarbon portion (B1) and an alkylene oxide portion (B2). the solvent (S) comprises water (S1). The composition can be used for a top coat composition, which can exhibit at least one of properties of advanced material or high performance material. The composition can be used in the nanotechnology process to make semiconductor device / display device application, for example liquid crystal, quantum dot or OLED display fabricated on a substrate, and controlled by semiconductors.
