PROBLEM TO BE SOLVED: To provide a polyurethaneurea resin composition for gravure printing ink which is excellent in any one of printing physical properties such as printability, laminate strength, blocking resistance and retort suitability in a non-toluene solvent system, without detection of elution of cyclic diester that possibly imparts an adverse effect to a taste test of packaged contents.SOLUTION: Gravure printing ink using a polyurethaneurea resin composition which contains 20 wt.% or more of 2-butyl-2-ethyl-1,3-propanediol and 1,2-propylene glycol in total glycol of polyester polyol used in a polyurethaneurea resin is excellent in any one of printing physical properties such as printability, laminate strength, blocking resistance and retort suitability in a non-toluene solvent system, without detection of elution of cyclic diester that possibly imparts an adverse effect to a taste test of packaged contents.SELECTED DRAWING: None |
