Described herein is an ink composition resistant to smearing, particularly when used in combination with adhesives, such as those containing polyols, including polyurethane adhesives. The present ink system is heat resistant, that is, it can withstand elevated temperatures, such as baking and cooking temperatures, and thus is suited for printing on food packaging in which the food contents are cooked in the packaging. The composition includes one or more of an elastomeric polyurethane resin, a styrene maleic anhydride copolymer, a polyurethane-polyol resin, and a group IV metal chelating agent.
