<P>PROBLEM TO BE SOLVED: To provide spherical fine particles which are used for an anti-reflective film related to an optical measure such as anti-reflection (AR) and has an excellent low reflection property without deteriorating transparency, to provide an anti-reflective resin composition which contains the low reflective transparent particles and has a good coating property and to provide an anti-reflective film which is made by using the anti-reflective resin composition and is used for picture display devices of CRT, PDP, LCD, PLD and ELD etc. <P>SOLUTION: The low reflective transparent spherical particle consists of a spherical core particle of refractive index n<SB>1</SB>and a shell layer made of organic polymer of refractive index n<SB>2</SB>and has the total reflectance R for the whole wavelength region of visible light of ≤2.5%: wherein, the refractive index n<SB>1</SB>> the refractive index n<SB>2</SB>is satisfied and the thickness of the shell layer is in the range of 100±50nm. The low reflective coating resin composition including the low reflective transparent particles is applied on various kinds of transparent substrate layers and affords the low-reflection property to the layers. <P>COPYRIGHT: (C)2004,JPO |
