FLUORINATED POLYFUNCTIONAL (METH)ACRYLIC ESTERS, FLUOROMONOMER COMPOSITION, MATERIAL WITH LOW REFRACTIVE INDEX, AND LOWLY REFLECTIVE FILM

摘要

Fluorinated polyfunctional (meth)acrylic esters represented by general formula (1), a fluoromonomer composition containing the same, a material with a low refractive index obtained by curing the monomer composition, and a lowly reflective film comprising the material with a low refractive index wherein: R<1>, R<2>, R<3>, and R<4> are the same or different and each represents hydrogen, acryloyl, or methacryloyl, provided that at least either R<1> or R<2> and at least either R<3> or R<4> represent each acryloyl or methacryloyl; and R represents C2-12 fluoroalkylene having two or more fluorine atoms.
