Curable fluoropolymer, curable resin composition containing the same, and antireflection film

[Subject] The antireflection goods with which the antireflection film in which abrasion-proof nature and wear resistance have been improved, and still such an antireflection film were covered are offered maintaining the 硬化性含 fluoride polymer which can realize high hardness-ization to polymer by optical hardening while maintaining a low refractive index, and the antireflection effect. [Solution means] The inside of formula (1) : * (A) * (M) * [type and structure unit M is a formula (M). : (The inside of a formula, X) 1 And X 2 -- or [that it is the same] -- or -- differing -- H or F;X 3 H, F, and CH 3 Or CF 3 ;X 4 And X 5 -- or [that it is the same] -- or -- differing -- H, F, or CF 3 ; Rf is Y to the 含 fluoride alkyl group which has an ether bond of the 含 fluoride alkyl group of the carbon number 1*40, or the carbon number 2*100.1 (Y 1 The organic group which 1*3 organic groups of 1 value of the carbon number 2*10 which has an ethylene nature carbon * carbon double bond have combined with 末端; as for a, integer;b and c of 0*3 are a structure unit originating in the 含 fluoride ethylene nature monomer which is the same or is shown by a difference, and 0 or 1.
