摘要： There is disclosed a holder for a stick-type cosmetic case which has an end portion of which the transverse outer size is smaller than that of the other portion of the cosmetic case. The holder includes: a holder body; a cover member; and a slanting surface. The holder body includes bottom and a peripheral walls defining a hollow for receiving the cosmetic case. The peripheral wall includes front and rear portions. The cover member is pivotally connected to the rear portion of the peripheral wall so as to open and close the hollow. The slanting surface extends between the bottom wall and the rear portion of the peripheral wall. The slanting surface inclines in such a manner that its rear edge is positioned at a higher level than its front edge. The distance between the front edge of the slanting surface and the front portion of the peripheral wall is less than the length of the cosmetic case and not less than the length of the other portion of the cosmetic case. The distance between the rear edge of the slanting surface and the lower face of the cover member is less than the transverse outer size of the other portion of the cosmetic case when the cover member is in its closed position. The holder further includes an opening or openings for allowing the end portion of the cosmetic case to project outward from the outer face of the front portion when the cosmetic case is in the hollow.

摘要： A silver halide photographic material is provided which exhibits nearly equal sensitivities and gamma values with respect to yellow, magenta and cyan to form a black-and-white image of neutral black or sepia tone, even when it is processed with a color developer free from benzyl alcohol. The silver halide photographic material is made up of a substrate and at least one silver halide emulsion layer formed on the substrate. The silver chloride content of silver halide grains constituting the silver halide emulsion layer is 95 mole % or above, the silver halide emulsion is spectrally sensitized by a specific sensitizing dye, and the silver halide emulsion layer contains a yellow coupler, a magenta coupler and a cyan coupler. The image-forming process is characterized by developing the silver halide photographic material with a color developer substantially free from benzyl alcohol.
