摘要: A diphenyl sulfone derivative represented by general formula (I), and a recording material containing at least one such being excellent in the preservability of non-image area resistances to plasticizer oil. In Y represents linear or branched (un)-saturated C1-C12 hydrocarbon group, C1-C8 group having an ether linkage, (a) (wherein R methylene ethylene); R?1, R2, R3 R4? represent each lower alkyl alkenyl; m integer 0, 1 2; n, p, q r 0 4, provided when are 2 above, may be different from another.
