摘要： A silver halide color photographic material comprising a transparent support having provided on the frontside thereof at least one hydrophilic colloid layer at least one layer of which is a photosensitive silver halide emulsion layer, said photographic material further comprising a transparent magnetic recording layer provided on the backside of the transparent support containing a ferromagnetic fine powder dispersed in a binder at a coverage of 4.times.10.sup.-3 g/m.sup.2 or more and having a gray degree of transmission density of 70% or more and an average transmission density of 0.5 or less in the visible region. The present invention provides a recording material for recording information both optically and magnetically without adversely affecting the color balance.

摘要： A peel-apart instant film unit including two separate sheets comprising a photosensitive sheet and an image-receiving sheet, has a coloring member provided on one end of the photosensitive sheet so as to contact a developer reagent spread between the two sheets for processing. The coloring member is adapted to change in color upon the completion of the processing of the film unit as a result of the chemical reaction of the coloring member brought into contact with the developer reagent. The color change of the coloring member, which is observed from the outside of the film unit, indicates the completion of the processing of the film unit. The coloring member includes a time delay substance that initially separates the reagent spread between the sheets, from the substance that changes color. That time delay substance is permeable by the reagent at a rate such that the reagent reaches that substance and causes the color change only upon the completion of the development of the film unit.
摘要翻译：包含感光片和图像接收片的两片分离片的剥离速成膜单元具有设置在感光片的一端上的着色部件，以与两片之间展开的显影剂接触进行接触处理。着色部件由于与显影剂试剂接触的着色部件的化学反应而使膜单元的处理完成而变色。从胶片单元的外部观察到的着色部件的颜色变化表示胶片单元的处理完成。着色部件包括时间延迟物质，其最初将从片材之间扩散的试剂与颜色变化的物质分离。该延时物质可以通过试剂渗透，使得试剂达到该物质，并且仅在膜单元的显影完成时才引起颜色变化。
