Patent ID: 8617693

Claim:
An antireflection laminate which comprises a refractive index layer that has a refractive index of 1.45 or less, wherein the refractive index layer is a cured product obtained by irradiating a refractive index layer forming composition with ionizing radiation; wherein the refractive index layer forming composition comprises: an ionizing radiation curable resin, a hollow particle having an inside that is porous or hollow and is covered with an outer shell layer, and said shell layer has a surface that is modified with a crosslinkable group(s), and a solid particle having an inside that is neither porous nor hollow, and a surface that is modified with a crosslinkable group(s); wherein the crosslinkable group(s) on the surface of the hollow particle and the crosslinkable group(s) on the surface of the solid particle comprise a silane coupling agent selected from the group consisting of: 3-methacryloxypropyltrimethoxysilane, 3-methacryloxypropyltriethoxysilane, 3-acryloxypropyltrimethoxysilane, 3-acryloxypropyltriethoxysilane, 3-methacryloxypropylmethyldimethoxysilane, 3-methacryloxyproplmethyldiethoxysilane, 2-methacryloxypropyltrimethoxysilane and 2-methacryloxypropyltriethoxysilane; wherein the refractive index layer contains 5 to 50 parts by weight of solid particles having a surface that is modified with a crosslinkable group(s), with respect to 100 parts by weight of hollow particles having an inside that is covered with an outer shell layer which has a surface that is modified with a crosslinkable group(s); and wherein the average particle diameter A of the solid particles has the following relationship with the average particle diameter B of the hollow particles; 10 nmâ‰¦Aâ‰¦40 nm; 30 nmâ‰¦Bâ‰¦60 nm; and Aâ‰¦B.
