The present invention relates to a metallic paint composition composed of an acrylic main material part and an isocyanate curing agent part, and more specifically, to a metallic paint composition, wherein the acrylic main material part contains a nitrocellulose-modified acrylic resin and a high molecular weight acrylic resin as a base resin, and liquid phase paste, a urethane reaction promoter, an adhesion promoter, a wet additive and a solvent are contained as additives in a specific content ratio, therefore, the metallic paint composition is excellent in physical properties such as appearance, initial adhesion, water resistance, weather resistance and the like, thereby being useful as a coating material for automotive interior and exterior parts. 본 발명은 아크릴 주제부와 이소시아네이트 경화제부로 이루어진 메탈릭 도료의 조성물에 관한 것으로서, 더욱 상세하게는 상기 아크릴 주제부에는 니트로셀룰로오즈 변성 아크릴 수지와 고분자량의 아크릴 수지를 기재수지로 포함하고, 첨가제로서 액상 은 페이스트, 우레탄 반응촉진제, 부착증진제, 습윤첨가제 및 용제가 특정 함량비로 포함되어 있음으로써 외관, 초기부착성, 내수성, 내후성 등의 물성이 우수하여 자동차 내외장 부품용 도료로 유용한 메탈릭 도료 조성물에 관한 것이다.
