Water-based release coating containing fluorochemical

An adhesive article comprising

• a backing having first and second surfaces;
• an adhesive on at least a portion of the first surface of the backing;
• and
• a release composition on at least a portion of the second surface of the backing, wherein the release composition comprises a mixture of
• (A) from 0.1 to about 5 wt % of a fluoro(meth)acrylate (co)polymer or a fluorochemical urethane compound containing at least one fluorinated group having the formula —(CF2)nCF3, wherein n is an integer from 1 to 3;
• (B) from about 15 to about 50 wt % of a copolymer consisting of the reaction product of
• (a) from about 40 to about 70 wt % of an alkyl (meth)acrylate, wherein the alkyl group contains from 16 to 22 carbon atoms,
• (b) from about 3 to about 20 wt % of (meth)acrylic acid,
• (c) from about 20 to about 40 wt % acrylonitrile, and
• (d) from 0 to about 15 wt % of vinyl monomer, other than those monomers of (a) through (c) above;
• and
• (C) from 0 to about 84.5 wt % of an extender polymer wherein the wt %'s in said mixture are based on the total weight of solids in the release composition.
