FLUORINE-CONTAINING URETHANE (METH)ACRYLATE, CURABLE COMPOSITION, AND ANTIREFLECTIVE FILM

摘要

It is an object of the present invention to provide a urethane (meth)acrylate that enables formation of a cured layer having a low reflectance and excellent excoriation resistance, a curable composition produced by using the same, and an antireflective film. In particular, there is provided a fluorine-containing urethane (meth)acrylate represented by General Formula (I) and having a fluorine atom content ranging from 25 to 60 mass % (where R1 and R2 each represent a specific fluorinated alkyl group, R3 and R4 each represent a hydrogen atom or a methyl group, A represents a trivalent linking group represented by any of Structural Formulae (A1) to (A4), and X and Y each independently represent a divalent linking group represented by any of Structural Formulae (a) to (c)) [in Structural Formula (c), R5 represents an alkyl group having 1 to 6 carbon atoms].

1. A fluorine-containing urethane (meth)acrylate represented by General Formula (I) and having a fluorine atom content ranging from 25 to 60 mass %(where R1 and R2 each independently represent a fluorinated alkyl group in which the number of carbon atoms to which fluorine atoms are directly bonded is from 2 to 6 or a fluorinated alkyl group which has a bond via an oxygen atom and in which the number of carbon atoms to which fluorine atoms are directly bonded is from 2 to 6 in total; R3 and R4 each represent a hydrogen atom or a methyl group; A represents a trivalent linking group represented by any of Structural Formulae (A1) to (A4); and X and Y each independently represent a divalent linking group represented by any of Structural Formulae (a) to (c))[in Structural Formula (c), R5 represents an alkyl group having 1 to 6 carbon atoms].
