| 摘 要： | 本文研究了邻苯二甲酸(H2PA)的用量以及H2PA的阴离子和阳离子对以苯并三氮唑银为银源的光敏热显影体系的影响.结果表明,在苯并三氮唑银体系中,邻苯二甲酸(H2PA)的阳离子(H+)降低了体系的pH值,还原剂的显影活性和H2PA与银离子的络合能力;而其阴离子(PA2-)则与苯并三氮唑银生成中间体,起到传输银离子的作用.

| Abstract: | We studied the effects of the amount of phthalic acid(H2PA),its positive ion and negative ion on photothermographic system based on silver benzotriazole as silver source.The results indicated that the positive ion(H+) of H2PA decreased the value of pH in the system,imaging activity of developer and the capability of H2PA combined with silver ions;the negative ion(PA2-) of H2PA created the intermediate with silver benzotriazole and carried silver ions during the thermo-imaging process. |
