Fluorine-containing polyfunctional (meth) acrylate composition low refractivity material and reflection reducing film

Abstract

Fluorine-containing polyfunctional (meth)acrylate represented by the formula (1), as well as a composition, a low refractivity material and a reflection reducing film in which the (meth)acrylate is utilized: ##STR1## wherein X stands for a fluoroalkyl group of C1-14 having 3 or more F, or a fluorocycloalkyl group of C3-14 having 4 or more F; Y.sup.1, Y.sup.2, and Y.sup.3 stand for H, an acryloyl group or a methacryloyl group, and at least two of Y.sup.1, Y.sup.2, and Y.sup.3 stand for an acryloyl group or a methacryloyl group; Z stands for H or an alkyl group of C1-3; and n and m is an integer of 0 or 1, and n+m=1.
