Abstract:
1. An antireflective film material, comprising: a polymer comprising copolymerized repeating units of mole fractions p and 1-p expressed by Formula (1): wherein p is a number in the range of 0<p<1; R 1a is a monovalent organic group which is capable of crosslinking, such that the repeating unit that corresponds to mole fraction p is selected from any one of the group consisting of the following: R 2 is a monovalent organic group containing a light-absorbing group; R 4 is a monovalent organic group which is capable of crosslinking, a hydroxyl group, an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, or a monovalent organic group containing a light-absorbing group; and n is a number in the range 0≦n≦1; an organic solvent; an acid generator; and a crosslinking agent.
