Described herein is a printing ink or coating composition that includes: (a) one or more elastomeric polyurethane resins with amine functionality having a glass transition temperature of about -45°C to about -70°C; (b) one or more acrylic resins based on a methacrylate/styrene copolymer with a glass transition temperature of about 45°C to about 110°C; (c) one or more nitrocellulose binders; (d) one or more solvents; and (e) optionally, one or more waxes and/or one or more colorants. The inks and coating compositions are well suited for printing onto shrink sleeve label substrates, such as by flexographic and gravure printing. The inks and coatings provide exceptional printability and resistance to chemicals, to softening, to re-wetting, and to set-off. |
