Abstract
Provided are overprint varnish (OPV) compositions containing high viscosity essentially non-aqueous dispersions that include acrylic core/shell polymer particles in a non-aqueous solvent such as mineral oil. Also provided are methods of coating a substrate with an OPV containing the non-aqueous dispersions to improve the properties of the OPV when used to coat a substrate, such as improved rub resistance, resistance to yellowing, and desirable gloss values.

An oxygen barrier coating composition comprising:
- a resin including a β-hydroxythioether linkage of the following formula:
- wherein:
- R1 is an alkyl, cycloalkyl, aryl, alkyl aryl, glycol or polyol group, wherein the alkyl, cycloalkyl, aryl, alkyl aryl, glycol or polyol group is substituted with one or more glycidyl groups, wherein the alkyl group of R1 is further substituted with one or more OH, cycloalkyl, aryl, heteroaryl or glycidyl ether groups or combinations thereof, and the cycloalkyl, aryl, alkyl aryl, glycol or polyol group of R1 optionally further is substituted with one or more alkyl, OH, cycloalkyl, aryl, heteroaryl or glycidyl ether groups or combinations thereof;
- and
- R2 is an alkyl, cycloalkyl, aryl, alkyl aryl or heteroaryl group, wherein the alkyl, cycloalkyl, aryl, alkyl aryl or heteroaryl group is substituted with one or more mercapto groups, wherein the aryl, alkyl aryl, alkyl, cycloalkyl or heteroaryl group optionally further is substituted with one or more alkyl, OH, cycloalkyl, aryl, heteroaryl or glycidyl ether groups or combinations thereof.
