<p>PURPOSE:To obtain a recording liquid, having excellent water, light resistance and preservation stability and suitable for ink jet, by dissolving or dispersing an oil-soluble dye and ultraviolet ray absorber, etc., in an oily phase, emulsifying and dispersing the oily phase in an aqueous medium. CONSTITUTION:The aimed recording liquid obtained by dissolving or dispersing an oil-soluble dye (e.g., C.I. Solvent Yellow 1) and an ultraviolet ray absorber (e.g., 2-hydroxy-4-methoxy-5-sulfobenzophenone) and/or an antioxidant (e.g., 2,6-di-tert-butyl-p-cresol), emulsifying and dispersing the resultant oily phase in an aqueous medium. Furthermore, the mode value of particle diameter distribution of emulsified and dispersed particles is preferably) <=10mum.</p> |
