하기 식 (1)로 표시되는 플루오로폴리에테르기 함유 아크릴 화합물이 낮은 굴절률을 가지며, 또한 일반적인 광중합개시제와 상용하여 투명한 조성물을 형성할 수 있다. V2-Rf2-C(=O)-NR1a[Y2(X2)b']2-a (1) (Rf2는 탄소수 1∼6의 퍼플루오로알킬렌기와 산소 원자에 의해 구성되는 수평균 분자량 500∼40,000의 2가의 퍼플루오로폴리에테르기. Y2는 탄소수 1∼20의 (b'+1)가의 유기 기. X2는 아크릴기 또는 α치환 아크릴기를 함유하는 1가의 유기 기이며, 1 분자 중에 평균하여 적어도 1개의 상기 아크릴기 혹은 α치환 아크릴기를 함유한다. R1은 수소 원자 또는 탄소수 1∼8의 1가의 탄화수소기. V2는 수소 원자, 불소 원자, 또는 -C(=O)-NR1a[Y2(X2)b']2-a로 표시되는 1가의 기. a는 0 또는 1. b'은 1∼10의 정수.) According to the present invention, a fluoropolyether group-containing acrylic compound represented by formula (1) has a low refractive index and is capable of forming a transparent composition by being compatibilized with a commonly used photopolymerization initiator.        (1):     V1-Rf2-C(=O)-NR1a[Y2(X2)b']2-a(In the formula, Rf2 represents a divalent perfluoropolyether group that is composed of a perfluoroalkylene group having 1 to 6 carbon atoms and an oxygen atom, while having a number average molecular weight of 500 to 40,000; Y2 represents a (b'+1)-valent organic group having 1 to 20 carbon atoms; X2 represents a monovalent organic group that contains an acryl group or an α-substituted acryl group, and at least one acryl group or α-substituted acryl group is contained in each molecule on average; R1 represents a hydrogen atom or a monovalent hydrocarbon group having 1 to 8 carbon atoms; V2 represents a hydrogen atom, a fluorine atom or a monovalent group represented by -C(=O)-NR1a[Y2(X2)b']2-a; a represents 0 or 1; and b' represents an integer of 1 to 10.)
