<P>PROBLEM TO BE SOLVED: To provide an antireflection film having a low refractive index layer which has a sufficiently low refractive index and is excellent in scratch resistance. <P>SOLUTION: There is provided an antireflection film having a low refractive index layer on a transparent support. The low refractive index layer is formed of a composition containing (A) a polymerizable fluorine-containing compound represented by the general formula (I) [Rf represents an 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 represented by the general formula (II), Q represents a polymerizable group or a hydrogen atom, a represents an integer of 3 to 20 and b and c each independently represents an integer of 0 to 100, provided that at least two of a Qs are polymerizable groups, and when the polymerizable group in the polymerizable fluorine-containing compound is polymerized, at least one of the calculated values of each cross-linking molecular weight is larger than 300], (B) a multifunctional monomer that does not contain fluorine, and (C) a photopolymerization initiator. <P>COPYRIGHT: (C)2013,JPO&INPIT |
