Patent ID: 7816417

Claim:
A water soluble antistatic photo-curable composition comprising: 5 to 15 wt % of fine conductive particles containing carbon nanotubes, 0.1 to 5 wt % of fumed silica, 10 to 20 wt % of water soluble acrylate based oligomer, 20 to 75 wt % of mono-functional monomer or multi-functional monomer, 0.1 to 5 wt % of photo-polymerization initiator, 0.1 to 5 wt % of additive including at least one selected from a group consisting of adhesion enhancer, dispersing agent, defoaming agent, leveling agent; and 50 to 150 parts by weight of pure water relative to the total 100 weight of the above ingredients, wherein wt % is in relation to the total weight of the composition, wherein said antistatic photo-curable composition is coated 5 μm to 10 μm of wet thickness by coating process to a surface of a conductive tile having a double-layer lamination to form a coating layer of the water soluble antistatic photo-curable composition with a thickness of 3 μm to 7 μm after completely drying the solvent.
