Antiglare film, method for producing the same, polarizing plate and image display device

A method for producing an antiglare film comprising:

• forming an antiglare layer having a thickness from 3 to 10 μm on one surface of a transparent support having a thickness from 20 to 70 μm by applying a composition containing the following components (A) to (D) on the transparent support, and drying and curing the applied composition:
• (A) a resin particle having an average particle size from 1.0 to 3.0 μm,
• (B) a curable compound having two or more curable functional groups in a molecule,
• (C) a smectite clay organic complex in which a smectite clay is intercalated with a quaternary ammonium salt represented by formula (I) shown below, and
• (D) a mixed solvent containing two or more kinds of ketone solvents;
• [(R1)3(R2)N]+.X− (1)
• wherein R1 and R2 are not the same, R1 represents an alkyl group, an alkenyl group or an alkynyl group, each having from 4 to 24 carbon atoms, R2 represents an alkyl group, an alkenyl group or an alkynyl group, each having from 1 to 10 carbon atoms, and X− represents an anion.
