First claim
Opening claim text (preview).
What is claimed is: 1 . A lubricant comprising: an ionic liquid, wherein the ionic liquid includes a cation that is represented by General Formula (A) below and is free from a fluorine atom, and an anion that is represented by General Formula (X) below and is free from a fluorine atom, where, in General Formula (A), R 1 is a group including a straight-chain hydrocarbon group having 6 or more carbon atoms, and R 2 , R 3 , and R 4 are each independently a hydrogen atom or a hydrocarbon group, where, in General Formula (X), X is represented by General Formula (Y-1) below, General Formula (Y-2) below, or General Formula (Y-3) below, where, General Formula (Y-1), n is an integer of from 0 to 5, where, General Formula (Y-2), Ar 1 is an aromatic group that has bond *1 and bond *2 at a meta position and may have a substituent, and where, in General Formula (Y-3), R 5 is a bond or an alkylene group and Are is an aromatic group that may have a substituent. 2 . The lubricant according to claim 1 , wherein in General Formula (A), one of R 2 , R 3 , and R 4 is a hydrogen atom. 3 . The lubricant according to claim 1 , wherein General Formula (X) is any one of structural formulae below, 4 . A magnetic recording medium comprising: a non-magnetic support; a magnetic layer disposed on the non-magnetic support; and the lubricant according to claim 1 disposed on the magnetic layer. 5 . An ionic liquid comprising: a cation that is represented by General Formula (A) below and is free from a fluorine atom; and an anion that is represented by General Formula (X) below and is free from a fluorine atom, where, in General Formula (A), R 1 is a group including a straight-chain hydrocarbon group having 6 or more carbon atoms, and R 2 , R 3 , and R 4 are each independently a hydrogen atom or a hydrocarbon group, where, in General Formula (X), X is represented by General Formula (Y-1) below, General Formula (Y-2) below, or General Formula (Y-3) below, where, General Formula (Y-1), n is an integer of from 0 to 5, where, General Formula (Y-2), Ar 1 is an aromatic group that has bond *1 and bond *2 at a meta position and may have a substituent, and where, in General Formula (Y-3), R 5 is a bond or an alkylene group and Ar 2 is an aromatic group that may have a substituent. 6 . The ionic liquid according to claim 5 , wherein in General Formula (A), one of R 2 , R 3 , and R 4 is a hydrogen atom. 7 . The ionic liquid according to claim 5 , wherein General Formula (X) is any one of structural formulae below,
