The present invention provides a modified polyolefin resin that can form a coating that exhibits excellent adhesion to a low-polarity base material, especially a poorly adherable polyolefin base material with no surface treatment even when being dried at low temperatures and has flexibility (bendability). Provided is a modified polyolefin resin that is a modified product of a polyolefin resin having a melting point (Tm) by a differential scanning calorimeter (DSC) of 60 to 165°C with a modifier comprising the following (A):
(A) a monomer mixture comprising Monomer Group (A-1) and Monomer Group (A-2) with a weight ratio of Monomer Group (A-1) to Monomer Group (A-2) ((A-1)/(A-2)) of 30/70 to 50/50.
本发明提供了一种改性聚烯烃树脂,它可以形成一种涂层,即使在低温干燥时,也能与低极性基材,特别是未进行表面处理的粘附性差的聚烯烃基材表现出优异的粘附性,并且具有柔韧性(可弯曲性)。本发明提供了一种改性聚烯烃树脂,它是由熔点(Tm)经差示扫描量热仪(DSC)测定为 60 至 165℃的聚烯烃树脂与改性剂的改性产物,改性剂包括以下 (A):
(A) 由单体组(A-1)和单体组(A-2)组成的单体混合物,单体组(A-1) 与单体组(A-2)的重量比((A-1)/(A-2))为 30/70 至 50/50。
