<P>PROBLEM TO BE SOLVED: To provide inkjet thermal recording ink which is useful for, for example, preparing at a low cost classified documents prepared by jetting ink containing a dye precursor or a color developer by inkjet to form a thermochromic recording member whose image part only is reversibly colored or decolored with a temperature change, is improved in a dispersing propertive of the dye precursor or the color developer to prevent plugging, and has the thermochromicity. <P>SOLUTION: The thermal recording ink composition is one wherein an inkjet recording ink composition which is jetted against recording paper coated with a material containing a color developer as one component of a thermochromic material comprises a dye precursor as one component of the thermochromic material, a dispersant comprising a specified polyoxyethylene glycerol fatty acid ester, a wetting agent, and a solvent. <P>COPYRIGHT: (C)2003,JPO |
