In curtain coating for multiple layers consisting of lower most layer, uppermost layer and intermediate layer, using coating liquid having viscosity more than 300 mPas for one layer or more of multiple layers improves amazingly the curtain coating stability against disturbance such as passing spliced portion of running web. The one layer or more layers for which coating liquid having viscosity more than 300 mPas is to be used is selected from intermediate layer. The curtain coating stability is further improved by combining the high viscosity coating liquid for intermediate layer with other technologies such as electrifying web, heating web upstream of coating point and/or keeping web tension higher than some specified value.

Method of curtain coating

An inexpensive, safe method for sterilizing an apparatus for the preparation of a recording material, which obviates troubles affecting a coated surface of the recording material caused by bacteria and fungi, does not cause changes in photographic performance (sensitivity, fog, graininess and sharpness), can prevent the appearance of 'resistant cells', and can comply with environmental problems, said method comprising sterilizing a surface of the apparatus being in contact with a coating composition for the recording material by use of a strongly acidic solution having a redox potential of 1,000 mV or more which is obtained by electrolysis of water.

A silver halide photographic material contains at least one aminoglycoside selected from the compound group consisting of gentamicin, amikacin, tobramycin, dibekacin, arbekacin, micronomicin, isepamicin, sisomicin, netilmicin, and astromicin, in a hydrophilic colloidal layer on a support.
