    摘要： A recording liquid including a coloring material, an organic solvent to disperse or to dissolve said coloring material, water, and a calix[n]arene-p-4-sulfonic acid (where n=4-8) in the form of free acid or its metal salt. The recording liquid is very suitable for inkjet recording using plain paper as recording medium. The recording liquid shows high storage stability, excellent color reproducibility with hard blurring property of mutual colors at superposed area thereof, and high resistively for light fading, for the sake of buffering nature based by both ion-capturing and -releasing, and hydrophobic material-capturing and -releasing bestowed by above-mentioned calix compound.

    摘要： A recording liquid comprising a coloring agent and water, wherein the recording liquid containing a polyol (A) having a solubility in water at 20° C. of 0.2 wt. % or more and not more than 4.5 wt. %, and at least one compound (B) selected from a group consisting of compound represented by formula (1) R1,R2,R3.N→O (where R1 and R2 are an alkyl group or a hydroxyalkyl group having 1 to 3 carbon atoms, and R3 is an alkyl group or an alkenyl group having 10 to 20 carbon atoms), and of compound represented by formula (2) represented by R4,R5,R6.N—CH2—CO—O−(where R4 and R5 are an alkyl group or hydroxyalkyl group having 1 to 3 carbon atoms, and R6 is an alkyl group or alkyl group derived from cocoanut oil having 10 to 16 carbon atoms that may contain an amide group). The recording liquid shows synergistic effect including a high permeability with modified penetrating property capable of eliminating an increasing in optical density at backside-surface of printing medium, anti-color bleeding property, and an effect on reduction of blurring of colors, by combination use of the polyol (A) and compound (B). The polyol (A) has a small molecular weight so that the adsorbing speed onto the surface to be printed is very high, and has a property to render the nitrogen moiety of the compound (B) into positive charge. The compound (B) effectuates on compound (A) to make it to be insoluble.
