Abstract
A polymer useful in forming coatings for articles is provided. The polymer is an acrylic copolymer formed as the reaction product of a plurality of monomers which include an alkyl (meth)acrylate, a quaternary amine (meth)acrylate, a hydroxyalkyl (meth)acrylate, an N-vinyl lactam, an ethylenically unsaturated carboxylic acid, and a fluorinated (meth)acrylate. The polymer is formed in the presence of surfactants, preferably by sequential polymerization of two separate monomer mixtures. To form a coating, the polymer is blended with an elastomeric material such as nitrile rubber latex. The resulting coating is useful both as a print coating for substrates used with ink jet printers and as a coating for rubber articles.

- an ethoxylated (meth)acrylate;
- an N-vinyl lactam;
- an ethylenically unsaturated carboxylic acid;
- and
- a fluorinated (meth)acrylate.
A method for making a polymer comprising the steps of:
- blending first and second monomer mixtures, each of the first and second monomer mixtures independently comprising:
- an alkyl (meth)acrylate;
- a quaternary amine (meth)acrylate;
- a hydroxyalkyl (meth)acrylate;
- an ethoxylated (meth)acrylate;
- an N-vinyl lactam;
- an ethylenically unsaturated carboxylic acid;
- and
- a fluorinated (meth)acrylate;
- reacting the first monomer mixture to at least partially polymerize the first monomer mixture;
- adding the second monomer mixture to the at least partially polymerized first monomer mixture;
- reacting the second monomer mixture to produce a polymer product;
- and
