Abstract:
A coating solution comprising: a first solvent; 0.1 to 30 parts by weight of a polycarboxylic acid-based polymer relative to 100 parts by weight of the solvent; and 0.05 to 0.25 chemical equivalent of a zinc compound relative to an amount of carboxyl group in the polycarboxylic acid-based polymer, wherein a number average molecular weight of the polycarboxylic acid-based polymer is in a range of 40,000 to 10,000,000.
