摘要： A silver halide light sensitive photographic element comprising a support bearing on one side thereof at least one light-sensitive silver halide emulsion layer, wherein the emulsion layer or a separate hydrophilic colloid layer of the element comprises a soluble absorber dye of the following formula (I): ##STR1## wherein each M is H or a counterion; each R.sup.1 and R.sup.2 independently represents H or a photographically acceptable substituent; m+p equals from 1 to 4; n+q equals from 1 to 4; and each of r and t represents from 0 to 3. In preferred embodiments of the invention, the element comprises at least one red-sensitive silver halide emulsion layer, and a dye of formula (I) is coated on the same side of the support as the red-sensitive emulsion layer. In particularly preferred embodiments, the element comprises a support bearing on the same side at least one blue-sensitive silver halide emulsion yellow-image forming layer, at least one red-sensitive silver halide emulsion cyan-image forming layer, at least one green-sensitive silver halide emulsion magenta-image forming layer, and a dye of the formula (I) is coated in at least one of the emulsion layers or a separate hydrophilic colloid layer on the same side of the support. Dyes of formula (I) typically provide substantial absorption at short red wavelengths below about 630 nm, and photographic elements in accordance with the invention accordingly exhibit effective safelight performance for commonly used safelights emitting in the range of 560-630 nm, such as those using a Kodak Safelight Filter No. 8.
摘要翻译：一种卤化银感光照相材料，其包含一个支承体，该支撑体的一侧具有至少一个感光卤化银乳剂层，其中所述乳液层或所述元件的分开的亲水胶体层包含下式（I ）：其中每个M是H或抗衡离子; 每个R 1和R 2独立地表示H或照相可接受的取代基; m + p等于1至4; n + q等于1至4; 并且r和t中的每一个表示0至3.在本发明的优选实施方案中，元件包含至少一种感红卤化银乳剂层，并且将式（I）染料涂覆在载体的同一侧作为感红乳剂层。在特别优选的实施方案中，元件包括在同一侧上承载至少一种感蓝卤化银乳剂黄色图像形成层，至少一种感红卤化银乳剂青色图像形成层，至少一种绿 - 敏感的卤化银乳剂品红色图像形成层和式（I）的染料涂覆在载体的同一侧的至少一个乳剂层或单独的亲水胶体层中。式（I）的染料通常在低于约630nm的短红色波长下提供实质吸收，因此根据本发明的照相元件相应地显示出在560-630nm范围内发射的常用安全灯的有效安全性能，例如使用 Kodak Safelight过滤器8号。
