The present invention is a coating composition comprising at least one first water insoluble polymer having a Tg equal to or less than 30° C. and at least one second water insoluble polymer having a Tg equal to or greater than 60° C. wherein the first polymer comprises a monomer at a weight percent of 75 to 100 of the monomer represented by the following formula 1:
wherein: X is selected from the group consisting of —Cl, —F, or —CN, and Y is each independently selected from the group consisting of H, Cl, F, CN, CF3, CH3, C2H5, n—C3H7, iso—C3H7, n—C4H9, n—C5H11, n—C6H13, OCH3, OC2H5, phenyl, C6F5, C6Cl5, CH2Cl, CH2F, Cl, F, CN, CF3, C2F5, n—C3F7, iso—C3F7, OCF3, OC2F5, OC3F7, C(CF3)3, CH2(CF3), CH(CF3)2, COCF3, COC2F5, COCH3, COC2H5; and the second polymer is a microgel particle.
