본 발명, 아크릴 중합체의 총 중량을 기준으로, 하이드록실-작용성 (메트)아크릴레이트 단량체 및/또는 하이드록실-작용성 (메트)아크릴아마이드 단량체의 잔기를 포함하는 구성 단위를 60 중량% 초과로 포함하는 아크릴 중합체; 및 아크릴 중합체와는 상이한 이온성 염 기-함유 필름-형성 중합체를 포함하는, 전착성 코팅 조성물에 관한 것이다. 또한 코팅, 코팅된 기재 및 기재를 코팅하는 방법이 개시된다. The present invention is directed to an electrodepositable coating composition comprising an acrylic polymer comprising greater than 60% by weight of constitutional units comprising the residue of a hydroxyl-functional (meth)acrylate monomer and/or a hydroxyl-functional (meth)acrylamide monomer, based on the total weight of the acrylic polymer; and an ionic salt group-containing film-forming polymer different from the acrylic polymer. Also disclosed are coatings, coated substrates, and methods of coating a substrate.
