Thermosensitive recording material |
摘要 |
A thermosensitive recording material with a high resistance to fogging has a thermosensitive colored image-forming layer formed on a support and includes at least one colorless dye precursor, a color-developing agent and a binder, the dye precursor being contained in a plurality of fine solid composite particles prepared by dissolving a solute including the dye precursor in a solvent which includes a polymerization component including a polyvalent isocyanate compound; emulsifying the resultant solution in an aqueous medium; and subjecting the aqueous emulsion to a polymerization reaction to thereby form the fine solid composite particles in which the dye precursor is solid-dissolved in a solid thermoplastic resin matrix formed from a resultant polyurea or polyurethane polyurea resin. <IMAGE> |
