The present invention relates to a hydrophilic antimicrobial coating composition for an air conditioner evaporator of a vehicle with improved durability. In one embodiment of the present invention, the antimicrobial composition comprises a hydrophilic organic polymer with molecular weight in the range of about 4,000 to 8,000, a smoothing agent, an antimicrobial agent, and deionized water. In particular, the degree of polymerization between the hydrophilic functional group and a crosslinking group of the hydrophilic organic polymer is greatly improved. The antimicrobial composition is prepared with particles with a diameter of a few nanometers, which increases the number of particles per unit area and reduces the decomposition rate of the coated layer.
