FLUORINATED URETHANE (METH)ACRYLATE, CURABLE COMPOSITION, AND ANTIREFLECTIVE FILM

摘要

The purpose of the present invention is to provide: a urethane (meth)acrylate which enables the production of a cured layer having low reflectance and excellent scratch resistance; a curable composition which is produced using the urethane (meth)acrylate; and an antireflective film. The present invention provides a fluorinated urethane (meth)acrylate which is represented by general formula (I) (wherein R1 and R2 independently represent a specific fluorinated alkyl group; R3 and R4 independently represent a hydrogen atom or a methyl group; A represents a trivalent linking group represented by any one of structural formulae (A1) to (A4); and X and Y independently represent a bivalent linking group represented by the structural formula (a), (b) or (c)) [in structural formula (c), R5 represents an alkyl group having 1 to 6 carbon atoms]) and has a fluorine atom content of 25 to 60 mass%.
