    • The present invention provides a reagent composition for measurement of ionic strength of liquid samples (especially for measurement of specific gravity of urine), which contains at least one phosphoric diester, at least one pH buffering agent, and at least one pH indicator. The present invention also provides a test tool containing the reagent composition which may be a test strip made by impregnation, coating, or printing of the composition. The reagent composition and the test tool are convenient and less susceptible to pH and temperature of the samples, measurement timing, etc. The compounds shown by the following general formula (1): ##STR1## wherein R.sub.1 and R.sub.2 in the formula (1) represent straight or branched alkyl groups containing 4-20 carbon atoms, phenyl groups which may be substituted, benzyl groups which may be substituted, or groups containing polyalkylene glycol chains, are preferable as a phosphoric diester.
    • 本发明提供了用于测量液体样品(特别是用于测量尿比重)的离子强度的试剂组合物,其含有至少一种磷酸二酯,至少一种pH缓冲剂和至少一种pH指示剂。 本发明还提供了含有试剂组合物的测试工具,其可以是通过浸渍,涂覆或印刷组合物制成的测试条。 试剂组合物和试验工具方便,对样品的pH和温度不敏感,测定时间等。下列通式(1)表示的化合物:其中式(1)中的R 1和R 2 (1)表示作为磷酸二酯,优选含有4-20个碳原子的直链或支链烷基,可被取代的苯基,可被取代的苄基或含有聚亚烷基二醇链的基团。

    • An ink composition for thermal transfer using a basic dye, or a cationic dye, is disclosed. The ink composition for thermal transfer contains the basic dye and an organic high polymer, with the basic dye being dissolved or dispersed into the organic high polymer with a solubilizing agent compatible with both the basic dye and the organic high polymer. The solubilizing agent is an amphipathic compound, preferably, having an HLB value of 7 or greater. By forming an ink layer containing the ink composition for thermal transfer on a base, an ink ribbon for thermal transfer is formed. A thermal transfer target sheet having a receptor layer containing an interlayer compound substituted by an ion exchangeable with the basic dye and a binder resin is used. The ion exchangeable with the basic dye is exemplified by an organic ion, such as an organic onium ion. The ink layer of the ink ribbon for thermal transfer and the receptor layer of the thermal transfer target sheet are superposed to face each other, and the basic dye contained in the ink layer is transferred onto the receptor layer by heating.
    • 公开了一种使用碱性染料或阳离子染料进行热转印的油墨组合物。 用于热转印的油墨组合物含有碱性染料和有机高聚物,碱性染料用与碱性染料和有机高聚物相容的增溶剂溶解或分散在有机高分子中。 增溶剂是两亲性化合物,优选HLB值为7以上。 通过在基底上形成含有热转印用油墨组合物的油墨层,形成热转印用墨带。 使用具有含有被碱性染料可交换离子取代的层间化合物的接收层和粘合剂树脂的热转印目标片。 与碱性染料可交换的离子的例子有有机离子,例如有机鎓离子。 用于热转印的墨带的油墨层和热转印目标片材的受体层叠加以面对彼此,并且通过加热将包含在油墨层中的碱性染料转移到受体层上。
