A silver halide photographic material is disclosed, which comprises at least one compound represented by the following general formula (1) or (2): ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 each represent a C.sub.25-70 alkyl group; X, Y and Z each represent a divalent bridging group; A and B each represent any unit selected from the group consisting of --(CH.sub.2 CH.sub.2 O).sub.a --, --(CH.sub.2 CH(OH)CH.sub.2 O).sub.b --, --((CH.sub.2).sub.c CH(R)CH.sub.2 O).sub.d --, and --(CH.sub.2 CH.sub.2 O).sub.e --(CH.sub.2 CH(OH)CH.sub.2 O).sub.f --((CH.sub.2).sub.c CH(R)CH.sub.2 O).sub.g -- in which c represents an integer 1 to 3 and R represents H, CH.sub.3 or phenyl group; D represents a hydrogen atom or C.sub.1-8 alkyl group; and a represents 5 to 40, b and d each represent 5 to 30, e represents 0 to 40, and f and g each represent 0 to 30.
A plastic film or coated paper has a hydrophilic colloid layer thereon comprising particles with the average particle size of 0.5 to 20.mu. coated with a water-repellent material. The water-repellent material is selected from the group consisting of silicone, a silane compound, a fluorine-containing compound and a silane coupling agent. A silver halide photographic light-sensitive material comprises a hydrophilic colloid layer comprising particles with the average particle size of 0.5 to 20.mu. coated with a water-repellent material.
A radiographic film package for non-destructive testing purposes has been developed, comprising a radiographic film sheet which is composed of a film support coated at both sides with one or more silver halide emulsion layer(s) and one or more non-light-sensitive protective antistress coating(s) thereover, and a wrapper around said film sheet which is light-opaque and air-tight, and which comprises a heat-sealable thermoplastic layer at the inner side of the wrapper, a transparent polymer layer at the outer side of the wrapper and a layer of aluminum located between said transparent polymer layer and said heat-sealable thermoplastic layer, and wherein at least one antistatic layer coating is provided between the said thermoplastic layer of said wrapper and the emulsion layers of said film sheet.
A heated development/transport roller having improved film release properties is provided by applying a fluorocarbon coating on the outer surface of the roller. The fluorocarbon coating may be applied onto the resilient layer surface of the roller by simply wiping a solution of the fluorocarbon material onto the resilient layer surface. There is no need for special coating conditions nor any post thermal curing or fusing conditions. The solvent is removed by application of heat either from the heating means of the roller or from an external heating source. The fluorocarbon coating provides improved film release and transport characteristics especially when applied to a hot silicone coated aluminum roller.
A silver halide photographic material is provide having at least one silver halide emulsion layer on one surface of a support and having on the other surface of the support, a backing layer containing a mat agent comprising grains having a mean grain size of 15 .mu.m or more in a proportion of at least 5% by volume. Due to the presence of the particular mat agent, the material has improved feedability and has small amount of haze.
