摘要

A resin modifier containing an active ingredient comprising a polyester having a hydroxyl value of 30 mgKOH/g or above and a weight-average molecular weight of 1,000 to 500,000 and prepared by the polycondensation of a polybasic higher carboxylic acid and a polyhydric alcohol component containing an at least trihydric alcohol and/or a polyvalent epoxy compound; and a resin composition containing the modifier. Moldings produced from the composition are excellent in coatability, adhesives and printability.
