Mitigation of mineral oil migration in pressure-sensitive labels and films

A curl-resistant composition comprising:

• a polymeric substrate having a first side and a second side;
• a printable coating layer on the first side;
• an adhesive-receptive coating layer on the second side, wherein the adhesive-receptive coating layer comprises acrylic polymer;
• and
• a barrier layer to mineral-oil migration, wherein the barrier layer is located directly between and on the adhesive-receptive coating layer and the polymeric substrate, and wherein the barrier layer consists essentially of:
• (i) polymers of polyvinyl alcohol, ethylene vinyl alcohol, polyester, polyamide, or combinations thereof;
• and (ii) optionally additives;
• wherein there is no adhesive transfer between a glass or metal plate and the adhesive-receptive coating layer when peeling the curl-resistant composition from the glass or metal plate at 180 degrees at 24 hours from adhesion at a peeling speed of 300 mm/min and peel strength at or below 1450 g/25 mm regardless of whether the adhesive-receptive coating layer is water-based or solvent-based;
• wherein the barrier layer provides a barrier to mineral-oil migration of 0.1 μg/day*dm2 or less at 40° C. for 40 days, and
• wherein the curl-resistant composition does not curl when heated for at least one hour at 60° C.
