Abstract:
1. An antireflective film comprising: a support; and at least one layer including an antireflective layer, wherein at least one of said at least one layer is a layer formed by ionizing radiation curing of a composition containing at least one compound selected from the group consisting of a compound represented by any one of formulae (1) to (5) and an organic peroxide, the composition further comprising a radical polymerization initiator and an ionizing radiation curable compound: wherein R 1 represents an alkyl group, a substituted alkyl group, an aryl group, a substituted aryl group or a heterocyclic group, and R 2 represents a hydrogen atom, a halogen atom, an alkyl group, an aryl group or a nitro group; wherein X represents NR 3 , an oxygen atom, a sulfur atom or a carbon atom, R 3 represents a hydrogen atom or a 1-4C alkyl group, and A represents atoms forming an unsubstituted or substituted 5- or 6-membered carbon-containing heterocyclic ring together with the moiety N═C—X, the atoms including two or three carbon atoms, two nitrogen atoms bonded together or one nitrogen atom bonded to one carbon atom and being bound to the moiety N═C—X via a single bond or a double bond, and an atom or atoms may further be bound to the 5- or 6-membered heterocyclic ring; wherein X represents NR 4 , an oxygen atom, a sulfur atom or a carbon atom, R 4 represents a hydrogen atom or a 1-4C alkyl group, D represents an oxygen atom or a sulfur atom, A represents atoms forming an unsubstituted or substituted 5- or 6-membered carbon-containing heterocyclic ring together with the moiety N—C—X, the atoms including two or three carbon atoms, two nitrogen atoms bonded together or one nitrogen atom bonded to one carbon atom and being bound to the moiety N—C—X via a single bond or a double bond, an atom or atoms may further be bound to the 5- or 6-membered heterocyclic ring, R 5 and R 6 independently represent a hydrogen atom, an alkyl group or an aryl group, and R 7 and R 8 independently represent a hydrogen atom, an alkyl group, an aryl group or an aralkyl group, or R 7 and R 8 may be combined with each other to form a pyrrolidine, piperidine, morpholine or N-substituted piperazine ring together with the nitrogen atom; wherein the cyclic group B containing Q represents an unsubstituted or substituted aromatic ring or heterocyclic group, Q represents a nitrogen atom or a carbon atom, and R 11 represents an alkyl group, a halogen atom, a halogen-substituted alkyl group, or an unsubstituted or substituted aromatic ring group; wherein E wherein the antireflective layer comprises a low refractive index layer formed by use of a coating solution containing a vinyl monomer having a polysiloxane moiety.
