含内部调变剂的卤化银颗粒的感光乳剂

Photographic emulsion containing AgX grains having inner modifier

本文概述了柯达公司近年来提出的在对辐射光敏感的卤化银颗粒中,具有一个面心的立方晶体点阵结构。内部含有一种亚硝酰基配位体和一个过渡金属,如Ru(钌),Re(铼)、Os(锇)所组成的六配位体的络合物,对卤化银颗粒进行内部调变。这种乳剂颗粒用于印刷制版明室片时,可获得优良的对辐射光的感光度,提高反差;用于对辐射光敏感的彩纸,可减少低照度的互易律失效。

This paper presents an achievement disclosed by Kodak Co. in recent years,namely light-sensitive AgX grains with face-centered crystal lattice enclosing a hexa-coordinate complex composed by a nitrosyl coordinate and a transicient metal e. g. Ruthenium, Rhenium or Osmium,used as a modifier for AgX grains. These emulsion grains can perform excellent radiation sensitivity and higher contrast when used for making light room graphic arts film,and feable reprocity law failure effect at low intensity exposure when used for making color paper.
