Abstract

이 발명은 자외선 경화용 도료 조성물에서 사용되는 다음의 일반식 (I)로 표시되는 카프로락톤 변성아민 아크릴레이트를 포함하는 광 증감제에 관한 것임. 이 광증감제는 지방족 1급아민에 윕실론 카프로락톤을 반응시켜 제조한 카프로락톤변성아민과 말단의 2중결합에 2개이상인 아크릴에스테르 모노머를 반응시켜 제조함. 이 광 증감제를 우레탄계 도막 조성물에 첨가하면 경화속도가 빠르고 생성된 도막조성물은 내후성과 내황변성이 우수함.This invention relates to the photosensitizer containing the caprolactone modified amine acrylate represented by the following general formula (I) used for the ultraviolet curable coating composition. This photosensitizer is prepared by reacting a caprolactone-modified amine prepared by reacting an aliphatic primary amine with whipsilone caprolactone and two or more acrylic ester monomers in a double bond at the terminal. When the photosensitizer is added to the urethane-based coating composition, the curing speed is high and the resulting coating composition has excellent weather resistance and yellowing resistance.
