测定并分析了亲水型光敏热成像材料的硬脂酸银以及加入其它组分后,在不同pH值时的pAg值变化.结果表明:随着pH值的增加,硬脂酸银体系的pAg值升高;硬脂酸银被AgBr取代后以及加入四氯邻苯二甲酸(H2PACl4)和酞嗪(PHZ)等组分,体系的pH值和pAg均发生相应的变化.
Changes of pAg values of silver stearate and after adding other components at different pH in hydrophilic photothermographic materials were measured and analyzed. The results showed that pAg values of silver stearate increased with increasing the pH; in addition, the pH and pAg values changed after substituting silver stearate by AgBr or adding tetrachlorophthali9 acid (H2PACl4) and phthalizine (PHZ).
