PURPOSE:To obtain a recording material whose light resisting solidity is excellent by including an N, P, O, and S series cation radiacal compound having an aromatic ring in a system wherein an electrodonating color former and an electron accepting developer are included. CONSTITUTION:In a system wherein an electronating color former (e.g. crystal violet lactone or the like) and/or an electron accepting developer (e.g. alkylnaphthalene or the like) are included, one kind or more of compounds [e.g. tris (P-diethyl aminophenyl) aminum hexafluoroantimonate or the like] selected from N, P, O, and S series cation radial groups having an aromatic ring are included. Then this is applied on paper and the like and dried, and the desired recording material is obtained. |
