Publication number: 20030235793Abstract: A silver halide photographic material of the invention contains a support having on at least one surface thereof at least one photosensitive silver halide emulsion layer, and a surface protective layer. The silver halide photographic material of the invention may include a hydrophilic colloid layer containing a hydrophilic colloid, in addition to the surface protective layer. The silver halide photographic material of the invention contains at least two kinds of surfactants that are different from each other. One of the surfactants (type 1) has a fluoroalklyl group or a fluoroalkylene group. The other (type 2) is an anionic surfactant containing ethyleneoxy repeating units and having an alkyloxy group or an alkylcarbonyl group at an end thereof.Type: ApplicationFiled: May 22, 2003Publication date: December 25, 2003Inventors: Katsuhiko Kanazawa, Terukazu Yanagi, Yoshihisa Tsukada, Shinichi Ichikawa
