Abstract
It is an object of the present invention to provide a chlorinated polyolefin resin having favorable adhesion to a polyolefin resin and high solubility in a composition containing an alcohol-based solvent. The present invention provides a chlorinated polyolefin resin that exhibits, in infrared spectroscopy spectrum measurement, a peak area ratio A/B×100 of 10% or higher, a peak area ratio C/B×100 of 30 to 80%, and a peak area ratio A/C×100 of 30% or higher (wherein 'A' is the area of a peak resulting from hydroxyl groups, 'B' is the area of a peak resulting from methylene groups, and “C” is the area of a peak resulting from carbonyl groups). The present invention also provides an ink composition for gravure printing or flexography that contains the chlorinated polyolefin resin, a printed material obtained using the above composition, and a printing method using the above composition.
