COATING COMPOSITION FOR LOW REFRACTIVE LAYER, ANTI-REFLECTION FILM USING THE SAME AND IMAGE DISPLAYING DEVICE COMPRISING SAID ANTI-REFLECTION FILM

摘要

A composition for coating a low refractive layer, an antireflective film containing the low refractive layer formed by using the composition, and an image display device containing the film are provided to lower reflectivity and haze and to improve antifouling property and scratch resistance. A composition for coating a low refractive layer comprises at least two different kinds of fluorine-containing compounds represented by Rf-O-A-(O-CO-CR=CH2)a and the formula 2; and a reactive silicone compound represented by the formula 4 or 5, wherein Rf is a C1-C8 perfluoro group containing 3-37 fluorine atoms; A is the residue of a polyvalent alcohol dehydrated acid; R is H or a methyl group; a is an integer of 1-3; X1, X2 and X3 are identical or different one another and H or a methyl group; Y is a C1-C4 linear fluoroalkyl group containing at least two fluorine atoms or a C3-C14 fluorocycloalkyl group containing at least 4 fluorine atoms; R1 and R2 are identical or different each other and at least one of the two is a reactive group capable of carrying out curing reaction; and c is an integer of 3-1,000.
