Abstract
The present invention is a coating composition comprising a water insoluble polymer having a Tg less than 25° C. and comprising 75 to 100 weight percent of the monomer having the following formula: 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—CH11, n—C6H,13, 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.
Claims18
An image recording element comprising:
- a support;
- at least one image recording layer superposed on the support;
- and
- an overcoat layer overlying at least one image recording layer, said overcoat layer consisting essentially of a single component water insoluble polymer having a Tg equal to or less than 30° C. and comprising 75 to 100 weight percent of the monomer having 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, C2F5, n—C3F7, iso—C3F7, OCF3, OC2F5, OC3F7, C(CF3)3, CH2(CF3), CH(CF3)2, COCF3, COC2F5, COCH3, COC2H5.
The image recording element of claim 4 wherein the element is an imaged ink-jet receiving element having at least one ink-receptive layer.
An image recording element having a protective overcoat thereon, the protective overcoat formed by the steps comprising;
- providing an image recording element;
- and
- applying an aqueous coating comprising a colloidal dispersion consisting essentially of a water insoluble polymer having a Tg equal to or less than 30° C. and comprising 75 to 100 weight percent of the monomer having 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 drying the aqueous coating to provide an image recording element having a protective overcoat.
