DIAR怎么记

Two DIAR couplers were synthesized with 2 ( isopropylamino) benzenethiol as timing group, which was synthesized from benzothiazole and triphosgene used as a substitute of phosgene, and good result was obtained.

从苯并噻唑开始，制备了2异丙氨基苯硫酚，并把它作为定时基团，合成了2种DIAR成色剂。在中间体的合成中，用固体光气代替光气得到了理想结果。

The inhibitor released from the reaction of DIR or DIAR coupler with QDI decreases the development rate of silver halide grams, so it controlled the formation rate of QDI.

DIR和DIAR成色剂在与QDI反应后所释放的显影抑制剂抑制了卤化银的显影进程，从而控制了QDI的形成速率。

The application of three DIAR couplers in color negative film is studied, and the data of sensitivity, fog, particularly, reduced graininess, improved interlayer effect have been obtained.

对3个DIAR成色剂在彩色负片中的应用进行了研究，得到了它们对感光度、灰雾影响的数据，特别是得到了它们在降低颗粒度和改善层间效应方面的数据。
