Abstract
Fluorine-containing polyfunctional (meth)acrylate represented by the formula (1), a monomer composition containing the (meth)acrylate, a low refractivity material prepared by curing the monomer composition, and a reflection reducing film provided with the low refractivity material. ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are the same or different groups, and each stands for a hydrogen atom, an acryloyl group, or a methacryloyl group, at least one of R.sup.1 and R.sup.2 and at least one of R.sup.3 and R.sup.4 stand for an acryloyl group or a methacryloyl group, R stands for a fluoroalkylene group having 2 to 12 carbon atoms and 2 or more fluorine atoms.
