<P>PROBLEM TO BE SOLVED: To provide an anti-reflection film having a low refractive index layer which is sufficiently low in refractive index and excellent in scratch resistance. <P>SOLUTION: The anti-reflection film has a low refractive index layer on a transparent support, the low refractive index layer being formed of a composition containing (A) a polymerizable fluorine-containing compound expressed by the general formula (I) [in which Rf represents a-valent organic group composed of a carbon atom and a fluorine atom, or a carbon atom, a fluorine atom and an oxygen atom only, A represents a single bond or a divalent linking group expressed by the general formula (II), Q represents a polymerizable group or a hydrogen atom, (a) represents integer numbers 3-20, and, (b) and (c) independently represent integer numbers 0-100 respectively, provided that at least two of the (a) Qs are polymerizable groups, and when the polymerizable group in the polymerizable fluorine-containing compound is polymerized, at least one of the respective calculated cross-linking molecular weight values is larger than 300], (B) a multifunctional monomer that does not contain fluorine, and (C) a photopolymerization initiator. <P>COPYRIGHT: (C)2010,JPO&INPIT |
