摘要: 三氮吲哚利嗪(TAI)是一种常用的银盐感光材料的稳定剂,许多研究表明TAI在化学增感或光谱增感乳剂中具有超增感作用[1,2],另有报道,它与光谱增感染料两者之间的添加次序对增感效果有很大的影响[1,6,7].

Abstract: This study examined the effect of hydroxy-tetraazaindene (TAI) on the sensitization of silver chloride emulsions sensitized by different dyes, as well as the effect of the adding order and concentration of TAI on the sensitization of silver chloride emulsion. The results indicate that there is a close relationship between the sensitization of emulsions by TAI and the molecular structures of dyes, and the effect was different when the adding order of TAI was changed. It was also discovered that the effect of the adding order of TAI and the spectrally sensitizing dye on the sensitization of silver chloride emulsion varied greatly with the increasing of the concentration of TAI.

Key words: hydroxy-tetraazaindene, spectral sensitization, silver chloride emulsion
