Definitions
- the present invention relates to a silver halide photographic light-sensitive material for graphic arts use, and more particularly to a silver halide photographic light-sensitive material for graphic arts use which is excellent in the ultra-high-speed processability as well as in the coatability.
- One method for achieving such a ultra-high-speed process ing as in the 60-second dry-to-dry time is to perform developing and fixing at raised temperatures, but the method is unacceptable because of affecting the preservability of processing solutions and increasing the vapor therefrom into the processing room. It is therefore desirable to manage to perform such the ultra-high-speed processing at a low temperature (not higher than 38°C). Also, reducing the amount of silver is effective in a high-speed processing.
- Another notable problem caused by reducing the amount of gelatin is the appearance of a lot of pinholes attributable to the matting agent contained usually in the outermost layer.
- the drying time is preferably within 15 seconds.
- dry-to-dry 80 to 150 seconds various measures such as increasing the drying air quantity, reducing the drying air humidity, raising the drying temperature, and using a far-infrared heater, ultrasonic oscillator or microwave dryer.
- the difference between such drying systems largely affects the change in the dimensions of a light-sensitive material before and after the processing thereof. Therefore, it is necessary to provide a light-sensitive material capable of showing the same dimensional change even when treated in different drying conditions.
- a silver halide photographic light-sensitive material of the invention comprises a support having thereon at least one light-sensitive silver halide emulsion layer and at least one non-light-sensitive hydrophilic colloid layer provided on the outside of said silver halide emulsion layer to the support, in which the total gelatin content of said layers containing said light-sensitive silver halide emulsion layer is 2.0 to 2.8g/m2 and at least one of said non-light-sensitive hydrophilic colloid layers contains a polymer latex.
