Abstract: An ethylenically unsaturated group-containing fluoropolymer, which is obtained by reacting a compound containing one isocyanate group and at least one ethylenically unsaturated group, and a hydroxyl group-containing fluoropolymer at an isocyanate group/hydroxyl group molar ratio of 1.1 to 1.9. According to the present invention, an ethylenically unsaturated group-containing fluoropolymer having superior antiscratching property, coating property and durability, as well as a curable resin composition and an antireflection film using the same can be provided.

Abstract: An antireflection film laminate comprising a low refractive index film on the surface side and a high refractive index film which is disposed under the low refractive index film in contact therewith, wherein the high refractive index film is formed as a discontinuous layer in the planar direction. If the high refractive index film is formed as a discontinuous layer, the high refractive index film can enter into the low refractive index film to restrain movement of the low refractive index film, and therefore an antireflection film laminate exhibiting superior antiscratching property and transparency can be obtained.

Abstract: A liquid resin composition containing (A) fluorine-containing polymer, (B) curable compound, (C) metal oxide particles having a number average particle size of 100 nm or less and (D) a solvent. When the composition is cured, the metal oxide particles (C) are distributed unevenly, the refractive index changes in the thickness direction by 0.05 to 0.8, so that there can be produced a cured film having a bilayer structure substantially consisting of a low-refractivity layer and a high-refractivity layer.

Abstract: A curing composition including: 100 parts by weight of (1) titanium oxide particles coated with oxide of one or more metal elements selected from the group consisting of silicon, aluminum, titanium, zirconium, tin, antimony and zinc, 1 to 150 parts by weight of (2) a curing compound, and 0.1 to 100 parts by weight of (3) acuring catalyst. An antireflective multilayer body (16) which successively includes, on a substrate layer (12), a high-refractive-index film (10) which is formed by curing this curing composition and has a refractive index of 1.60 or more and a low-refractive-index film (14) having a lower refractive index than that thereof exhibits excellent antireflection effect in the field in which an antireflection film is used.

Abstract: A antireflection laminate having a first layer formed on the outermost side and a second layer formed under the first layer. The second layer contains a needle-like antimony-containing tin oxide and may be a cured product prepared by curing an organic solvent type curable composition containing the needle-like antimony-containing tin oxide; a reaction product of a hydroxyl group-containing polyfunctional (meth)acrylate and a diisocyanate; a polyfunctional (meth)acrylate; and photoinitiator.
