<p>PURPOSE:To obtain the title composition having boiling resistance and a suitability for retorting and excellent storage stability by using a binder mainly consisting of a polyurethane resin soluble in an organic solvent and a polycarbodiimide compound. CONSTITUTION:The title ink is one wherein the binder mainly consists of a polyurethane resin soluble in an organic solvent and a polycarbodiimide compound containing at least two carbodiimide groups in the molecule and represented by the formula [wherein R1 and R2 are each (substituted) alkyl, cycloalkyl, aryl, aralkyl, alkaryl or a heterocyclic hydrocarbon group; and is an integer]. This composition is excellent in storage stability and adhesion to a plastics such as polyester, nylon, polyethylene or polypropylene used as a substrate when used in the form of a one-pack ink, and can provide a print having excellent properties such as a suitability for lamination and retorting.</p> |
