<p>A coating composition comprises a dispersion of fine particles of silica having a particle size of less than 300 nm, hydrophilic hydroxy-containing polymer, a first non-ionic surfactant comprising an alcohol containing perf luoroalkyl repeat units and ethylene oxide repeat units, and a second non-ionic surfactant selected from the group consisting of non-fluorine-containing surfactants that comprise a hydrophobic moiety and a hydrophilic moiety comprising hydroxy groups, wherein the hydroxy number of the second non-ionic surfactant is greater than 300. Also disclosed is an ink jet recording element so-coated. The invention can provide high image quality (reduced coalescence) of the inkjet recording element or increased stability of the coating composition.</p> |
