  • Patent number: 10052354
    Abstract: It is to provide a composition derived from lactic acid bacteria having an anti-allergic effect (an effect of suppressing allergic symptoms such as hay fever) synergistically, and a food product, pet food, etc. containing the composition. It is to prepare a composition having an anti-allergic action, containing Lactobacillus crispatus KT-11 strain, KT-23 strain, or KT-25 strain bacterial cells and viable bacteria, dead bacteria, or a processed product of bacterial cells of other lactic acid bacteria belonging to the genus Lactobacillus, genus Bifidobacterium, genus Leuconostoc, genus Enterococcus, genus Pediococcus, etc. at a biomass-converted ratio of 99:1 to 50:50, preferably 99:1 to 75:25.
    Type: Grant

  • Patent number: 5212054
    Abstract: A silver halide color photographic light-sensitive material of which the color reproducibility and printing suitability are kept improved against the variation of photographing conditions, such as a change in light source, is disclosed. The photographic material comprises a support and provided thereon a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a blue-sensitive silver halide emulsion layer, wherein at least one of said emulsion layers is of three-layer structure comprising a low-speed elemental emulsion layer, a medium-speed elemental emulsion layer and a high speed emulsion layer arranged in this sequence from the side facing the support, and a maximum color density of said medium-speed emulsion layer is not more than 0.35.

  • Patent number: H1112
    Abstract: A silver halide color photographic light-sensitive material improved in graininess, comprising a support having thereon a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a blue-sensitive silver halide emulsion layer, wherein at least one of the red-sensitive emulsion layer and the green-sensitive emulsion layer has the three-layered structure, in which the low speed silver halide emulsion layer, medium speed silver halide emulsion layer and high speed silver halide emulsion layer are coated on the support in this order; and the coating amount of silver in the layer increases in the order of the medium speed layer, low speed layer and high speed layer.

  • Patent number: H1243
    Abstract: A silver halide color photoqraphic light-sensitive material having an excellent graininess, sharpness and color reproducibility, particularly of green colors including yellowish qreen and bluish qreen is disclosed. Among silver halide emulsion layers, the blue-sensitive layer is located furthest from a support and the outside thereof, has a non-light-sensitive layer. And the optical specifications of these two layers are as specified in the claims.
