Fluorochemical-free paper coatings which simultaneously exhibit good oil and grease resistance, hydrophobicity, and release properties are aqueous dispersions containing a water insoluble vinyl polymer, an addition-curable organopolysiloxane which cures through hydrosilylation, an Si—H functional crosslinker, and a catalyst for addition curing of the addition-curable organopolysiloxane. High oleophobicity, hydrophobicity, and release properties are developed even at low coating weights. |
