PURPOSE:To obtain a recording image high in an ink absorbing speed and excellent in color developability in order to suppress the blur of ink, by treating a base material with a treatment agent prepared by compounding an amine compound and phosphoric ester as essential components and also compounding an org. acid and/or an inorg. acid if necessary. CONSTITUTION:As an amine compound A, there is no special limit if a compound having one or more basic nitrogen in the molecule thereof or a salt thereof is used and monoamine compounds, polyamine compounds or a salt of an org. or inorg. acid thereof or quaternary ammonium salt thereof can be used. As phosphoric ester B, water-soluble phosphoric ester such as trimethyl phosphate or triethyl phosphate is pref. Further, it is pref. to compound the org. acid and/or the inorg. acid C since ink absorbability is improved and blur is reduced. As a base material, paper can be representatively cited, but cloth, a resin film, synthetic paper, a resin molded body or the like can be also used. |
