A recording liquid comprising a coloring material, an organic solvent to disperse or to dissolve said coloring material, water, and a calix[n]arene-p-4-sulfonic acid(wherein 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 superimposed area thereof, and high resistivity 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.
一种记录液,由着色材料、分散或溶解所述着色材料的有机溶剂、水和游离酸或其金属盐形式的钙[n]炔-4-磺酸(其中 n=4-8)组成。该记录液非常适用于以普通纸为记录介质的喷墨记录。由于上述钙[n]烯化合物同时具有离子捕捉和释放以及疏水物质捕捉和释放的缓冲特性,该记录液具有很高的储存稳定性、出色的色彩再现性及其叠加区域的互色模糊性,以及很高的抗光褪色性。
