Coating composition for a protecting layer for image recording materials

摘要

The present invention is a coating composition comprising at least one first water insoluble polymer having a Tg equal to or less than 30 DEG C. and at least one second water insoluble polymer having a Tg equal to or greater than 60 DEG 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.
