A modified polyolefin resin is described. The modified polyolefin resin can enhance a cleaning property upon cleaning inside of a coating machine with a cleaning solvent including water, and is excellent in a balance between heat resistance and solution stability. The modified polyolefin resin is a polyolefin resin that is modified with an α,β-unsaturated carboxylic acid or a derivative thereof and with an amino alcohol having a primary or a secondary amino group.
