ANTIBACTERIAL AND ANTISTATIC MULTIFUNCTIONAL HARD COATING COMPOSITION, ITS COATING METHOD AND HARD COATING TRANSPARENT SHEET USING IT

摘要

Provided are a hard coating composition which is antibacterial, is excellent in contamination resistance and antistatic property and is improved in surface resistance, transparence, hardness and scratch resistance, a method for coating a plastic substrate by using the composition, and a hard coating transparent sheet prepared by the method. The hard coating composition comprises 1-10 wt% of a silver nanoparticle sol; 0.01-2.0 wt% of a conductive filler; 10-50 wt% of a radiation curing resin; 1-5 wt% of a photopolymerization initiator; and the balance of an organic solvent. Preferably the silver nanoparticle sol has an average diameter of 1-10 nm and comprises a silver nanoparticle coated with a silicone-based compound; the conductive filler is at least one selected from the group consisting of polyaniline, polypyrrole and polythiophene; and the radiation curing resin comprises at least one selected from mono- to trifunctional acrylic monomer.
