    • A package for diazo thermosensitive recording materials coiled round a core, which comprises a packaging paper being a water vapor permeability of more than 50 g/m.sup.2.24 hours and comprising a light-reflecting paper layer located as outer layer and a light-shielding paper layer located as inner layer.In the package of the invention, the packaging paper shields the recording material from the external heat and light. When internal humidity is increased such as by heating of the package such as higher than 50.degree. C., moisture passes through the packaging paper to the outside. Accordingly, fogging by precoupling of the packaged diazo thermosensitive recording materials, irrespective of the fixation type or not, is remarkably decreased, and the quality of the recording material can be maintained for a long period during storage.
    • 一种盘绕在芯上的重氮热敏记录材料的包装,其包括水蒸气渗透率大于50g / m 2·24小时的包装纸,包括位于外层的光反射纸层和遮光纸 层位于内层。 在本发明的包装中,包装纸将记录材料从外部的热和光屏蔽。 当内部湿度增加,例如通过加热包装如高于50℃时,水分通过包装纸到外面。 因此,无论固定类型如何,通过预先结合包装的重氮热敏记录材料的雾化明显减少,并且可以在储存期间保持长时间的记录材料的质量。

    • A color photographic light-sensitive material comprising a support having thereon, in sequence:(1) a blue-sensitive silver halide emulsion layer containing, dispersed in the emulsion using a high-boiling organic solvent, a yellow coupler represented by the following general formula (I): ##STR1## with the weight ratio of the high-boiling organic solvent for dispensing the coupler to the yellow coupler being 1.0:1 or less;(2) a green-sensitive silver halide emulsion layer containing a magenta coupler represented by the following general formula (II): ##STR2## (3) a red-sensitive silver halide emulsion layer containing a cyan coupler represented by the following general formula (III): ##STR3## (4) an ultraviolet light absorbing layer containing an ultraviolet light absorbent represented by the following general formula (IV): ##STR4## in which the substituents X, Z, and R.sub.1 -R.sub.12 are as defined in the specification. The color photographic light-sensitive material provides a dye image which is resistant to fading or discoloration by light, and in particular provides color prints having a well-balanced fading of the dye image composed of the three yellow, magenta and cyan colors.
    • 一种彩色照相感光材料,其中包含其上的载体,其顺序为:(1)感蓝卤化银乳剂层,其含有使用高沸点有机溶剂分散在乳液中的黄色成色剂,由下列通式 (I):用于分配成色剂的高沸点有机溶剂与黄色成色剂的重量比为1.0:1或更小的(I) (2)含有由以下通式(II)表示的品红色成色剂的感绿卤化银乳剂层:(2)(3)含有下列物质的青色成色剂的感红卤化银乳剂层 (III):(III)(4)包含由以下通式(IV)表示的紫外线吸收剂的紫外光吸收层:其中取代基X,Z和 R1-R12如说明书中所定义。 彩色摄影感光材料提供了耐受光的褪色或变色的染料图像,特别是提供了由三种黄色,品红色和青色组成的染料图像的平衡褪色的彩色印刷品。
