Provided is a composition for inhibiting the proliferation of bacteria belonging to the genus Collinsella, the composition containing at least one selected from sugar acid-containing oligosaccharides and salts thereof. The sugar acid is preferably selected from aldonic acid, uronic acid, and aldaric acid.

A hydrogel for treating body cavity injury is derived from a chitosan derivative obtained by bonding aldonic acid to an amino group of a glucosamine unit of chitosan by dehydration condensation. The hydrogel for treating the body cavity injury is granular, can be injected into a body cavity by utilizing an injector, and is used for treating the wound of the body cavity. A body cavity injury treatment kit is provided with a syringe, a tube connected to the syringe, and a granular body cavity injury treatment hydrogel filled into the syringe, the body cavity injury treatment hydrogel being derived from a chitosan derivative, the chitosan derivative is obtained by bonding aldonic acid to an amino group of a glucosamine unit of chitosan through dehydration condensation.

A photocatalytic paint according to the disclosure includes: photocatalytic particles containing tungsten oxide; a binder; and an aqueous dispersion medium. The binder includes a first binder and a second binder, or a dehydrated condensate of the first binder and the second binder. The first binder is a compound containing a trihydroxysilane group or a dehydrated condensate of the compound, and the second binder is an aliphatic hydroxy acid or an aldonic acid.

The purpose of the present invention is to improve the heat resistance of a polarizing plate comprising a polyvinyl alcohol-based resin film. A method for producing a polarizing plate (11) from a raw film (21), which is a polyvinyl alcohol resin film, comprises a swelling step for swelling the film by immersing the film in a swelling solution (14). The production method includes a dyeing step of dyeing the film by immersing the film after the swelling step in a dyeing solution (15). The production method includes a crosslinking step of immersing the film after the dyeing step in a crosslinking solution (16a, 16b) to crosslink the film. In the production method, in at least one of the swelling step, the dyeing step, and the crosslinking step, a stretching step for stretching the film is performed together. At least one of the swelling solution (14), the staining solution (15), and the crosslinking solutions (16a, 16b) contains an aldonate salt and a nitrate salt.
