Abstract:
1. An anti-reflection film comprising a low refractive index layer, wherein the low refractive index layer is formed by coating and curing a film-forming composition comprising: a block copolymer comprising: at least one polymer block [A] containing a repeating unit (F), the repeating unit (F) containing at least one of fluorine-containing alicyclic structures represented by formula (FI) and formula (FII); at least one polymer block [B] containing a repeating unit (S), the repeating unit (S) containing at least one group selected from the siloxane structure groups represented by formula (SI); and a repeating unit (H) having at least one reactive group capable of being involved in crosslinking reaction, the repeating unit (H) being in at least one of the polymer block [A] and the polymer block [B]; and at least one of a curing agent and a curing accelerator; wherein R 1 and R 2 , which are the same or different, each represents a fluorine atom or a —C j F 2j+1 group; j represents an integer of from 1 to 4; a represents 0 or 1; b represents an integer of from 2 to 5; and c represents 0 or 1; wherein R 3 and R 4 each represents a fluorine atom or a —CF 3 group; a represents the same number as in formula (FI); d represents 0 or 1; k represents 0 or an integer of from 1 to 5; 1 represents 0 or an integer of from 1 to 4; m represents 0 or 1; and (k+1+m) is an integer of from 1 to 6; wherein R 11 , R 12 , R 13 , R 14 and R 15 , which are the same or different, each represents an aliphatic group or an aromatic group.
