Abstract
This invention generally relates to a coating composition which provides a coating film with high hydrophilic resistance and high hydrophobic resistance. The coating composition contains a polymer formed from a monomer composition comprising (a) 45-85 wt % of ethyl ester of acrylic acid or methacrylic acid and (b) 15-54 wt % of itaconic ester with 1 or 2 carbon atoms as a binder of the coating composition, and the weight of sum of (a) and (b) is 65% or more based on the total weight of the polymer.
