Abstract

The present invention is a coating composition comprising at least one first water insoluble polymer having a Tg equal to or less than 30.degree. C. and at least one second water insoluble polymer having a Tg equal to or greater than 60.degree. 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: ##STR1## 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, CF.sub.3, CH.sub.3, C.sub.2 H.sub.5, n--C.sub.3 H.sub.7, iso--C.sub.3 H.sub.7, n--C.sub.4 H.sub.9, n--C.sub.5 H.sub.11, n--C.sub.6 H.sub.13, OCH.sub.3, OC.sub.2 H.sub.5, phenyl, C.sub.6 F.sub.5, C.sub.6 Cl.sub.5, CH.sub.2 Cl, CH.sub.2 F, Cl, F, CN, CF.sub.3, C.sub.2 F.sub.5, n--C.sub.3 F.sub.7, iso--C.sub.3 F.sub.7, OCF.sub.3, OC.sub.2 F.sub.5, OC.sub.3 F.sub.7, C(CF.sub.3).sub.3, CH.sub.2 (CF.sub.3), CH(CF.sub.3).sub.2, COCF.sub.3, COC.sub.2 F.sub.5, COCH.sub.3, COC.sub.2 H.sub.5 ; and the second polymer is a microgel particle.
