HIGH CONTRAST REDUCED ANTIREFLECTION MATERIAL, ITS PRODUCTION AND USE

摘要

PROBLEM TO BE SOLVED: To provide a reduced antireflection material excellent in high contrast function and reduced antireflection function by providing an reduced antireflection layer obtained by curing a curable coating solution containing specified proportions of a fluorine-containing polyfunctional (meth)acrylic ester and a fluorine-containing polymer. SOLUTION: The reduced antireflection material has high contrast function and reduced antireflection function on the surface of the base material. The reduced antireflection function is ensured by a reduced antireflection layer obtained by curing a curable coating solution containing 10-100 wt.% fluorine- containing polyfunctional (meth)acrylic ester as a component A and 90-0 wt.% fluorine-containing polymer as a component B. The high contrast function is ensured by using a blend of a black pigment and an adhesive applied on the reduced antireflection layer. The component A is represented by formula I or the like and the component B is a polymer containing >=50 wt.% constituent units based on an ester of formula II. In the formulae I and II, X1-X3 are each H or the like, Y1 and Yu4 are each fluorolakylene or the like and (m) and (n) are each 1 or 2.
