摘要:
A photographic image-forming method comprising imagewise exposing a silver halide photographic light-sensitive element containing a specific hydroquinone derivative in the silver halide emulsion layer of substantially the surface latent image type or at least one hydrophilic colloid layer thereof and then developing the exposed light-sensitive element in the presence of a specific hydrazine compound. The method forms a photographic image having markedly high negative gradation.

摘要:
A color photographic light-sensitive material containing at least one hydroquinone compound substituted with one or two tertiary alkyl groups having 15 carbon atoms, or a precursor thereof. The hydroquinone compounds are particularly useful for preventing color fog or color stain which is observed with color photographic light-sensitive materials.
摘要:
A method for manufacturing a plasma display apparatus includes bonding a panel to a sustaining board (chassis) with a sufficient bonding area. In a process of bonding the panel to the chassis, the panel is supported on the sustaining board (chassis) via a heat conducting sheet. Then the panel and the chassis are sandwiched between resilient pressuring boards, which are larger than the panel and the chassis. After that, a predetermined pressure is applied from at least one of the pressuring boards, thereby bonding the panel to the chassis via a heat conducting sheet.
