Abstract
Disclosed are coating compositions, coated articles made using said coating compositions and processes for preparing the same. More particularly disclosed are aqueous ink-receptive, water-based coatings which are smudgeproof and which will not wash off with water.
Claims46
A coating composition comprising:
- at least 5 weight percent of a polymer of a 2-oxazoline;
- at least 50 weight percent of polyethylene acrylic acid copolymer;
- and
- an aqueous liquid, said weight percents being based on the weight of the 2-oxazoline polymer and the polyethylene acrylic acid copolymer.

A coating composition comprising:
- at least 5 weight percent of a polymer of a 2-oxazoline;
- at least 50 weight percent of an olefin copolymer containing substantially neutralized pendant acid groups;
- a base capable of neutralizing acid groups;
- a carboxy functional acrylic ester polymer;
- a surfactant;
- and
- an aqueous liquid, said weight percents being based on the weight of the 2-oxazoline polymer, the olefin copolymer and the carboxy functional acrylic ester polymer.

1 more element
A process for producing a coated article having aqueous ink applied to it comprising the steps of:
- (a) providing a substrate;
- (b) coating at least one surface of said substrate with a coating composition formed by:
- (1) mixing an olefin copolymer containing pendant acid groups with a base capable of substantially neutralizing said acid groups and an aqueous liquid to form an aqueous solution;
- and
- (2) mixing said aqueous solution with an aqueous solution of a 2-oxazoline polymer;
- said coating composition comprising at least 5 weight percent 2-oxazoline polymer and at least 50 weight percent olefin copolymer containing pendant acid groups, said weight percents being based on the weight of the 2-oxazoline polymer and the olefin copolymer;
- (c) drying said coating;
- and
- (d) applying an aqueous-based ink to the coated substrate.
