A kit for bonding to biological hard tissues, containing a phosphorylated polysaccharide, a polyvalent metal salt other than phosphates, and a solvent. The adhesive composition for biological hard tissues provided by the kit for bonding to biological hard tissues is suitably used in for medical uses, such as cement for bones or dental cement. In addition, since the adhesive composition has excellent bio-absorbability, it is useful as fusion materials for artificial joint prosthesis, fusion materials for spine fracture, fusion materials for extremity fracture, filling materials for bone tumors in the region of orthopedics, filling materials and restorative materials at dental caries-defective sites, luting materials for prosthetic restorative materials such as inlay and crown, pulp-capping and lining materials, implant surface treatment materials, periodontal disease therapeutic materials, hyperesthesia preventive materials, dental pulp capping materials, substrates for DDS, substrates for systems engineering, and tissue bonding materials in the dental region.

Kit for adhering biological hard tissues

A dental composition for oral use, containing a phosphorylated saccharide (a), a polyphosphoric acid and/or a salt thereof (b), and a cationic bactericidal agent (c), wherein a ratio of a total amount of the phosphorylated saccharide (a) and the polyphosphoric acid and/or a salt thereof (b) contained to an amount of the cationic bactericidal agent (c) contained, i.e. {(a)+(b)}/(c), is from 0.05 to 20 in a weight ratio. The dental composition for oral use of the present invention can be suitably used for an oral cavity cleaning agent, including dentifrice agents such as a paste dentifrice agent, a powder dentifrice agent, and a liquid dentifrice agent, a mouse-wash agent, a troche, a tablet, a cream, an ointment, a bonding agent, a mouth spray, a coating agent to tooth surface or a dental prosthetic, a hypersensitive inhibitor, a therapeutic agent for periodontal diseases, that is applied to a periodontal pocket, wet tissue for oral cavity care, an oral refreshing agent, chewing gum, or a gargling agent, or the like.

Dental oral composition

A dental composition for oral use, containing a phosphorylated saccharide (a), a cationic bactericidal agent (b) and a solvent (c). By using the dental composition for oral use of the present invention, the adhesion of the bacteria in the oral cavity to the surfaces of the teeth can be suppressed for a long period of time; therefore, the dental composition for oral use can be suitably used for, for example, a mouse-wash agent, a dentifrice agent, a gargling agent, a mouse spray, a coating agent or a bonding agent to tooth surface or a dental prosthetic, a hypersensitive inhibitor, a therapeutic agent for periodontal diseases, that is applied to a periodontal pocket, or the like.

Oral composition for dental purposes

The present invention relates to a flame-retardant leather-like sheet having a soft hand, excellent surface touch and excellent appearance, which includes an entangled nonwoven fabric of microfine polyester fibers having an average single-fiber fineness of 0.5 dtex or less, and an elastic polymer contained inside the nonwoven fabric, wherein a flame-retardant is exhausted into the elastic polymer and wherein a flame retarder solution containing bubbles forcibly formed is applied to a back surface of the leather-like sheet so that the flame retarder is present in a region extending from the back surface to an inside of the leather-like sheet but is not present on side of a front surface of the leather-like sheet.

Flame-retardant leather-like sheet and process for producing the same

To provide a method of producing a nonwoven fabric for artificial leather and substrate for artificial leather which is capable of providing the substrate for artificial leather having a sufficient shape stability by producing the nonwoven fabric for artificial leather without causing serious damages to the scrim. A method of producing a nonwoven fabric for artificial leather, including a step of entanglement for uniting superposed fiber web and scrim by a needle punching, wherein the needle punching is performed in a manner satisfying the following formulae 1 and 2:&#x3c;2/cos(&#xd7;(&#x3c0;/180))&#x2003;&#x2003;(1)&#x3c;2/cos(&#xd7;(&#x3c0;/180))&#x2003;&#x2003;(2)wherein Sis a diameter of warps constituting the scrim, Sis a diameter of wefts constituting the scrim, Dis an angle between the warps and barbs which penetrate the scrim, Dis an angle between the wefts and barbs which penetrate the scrim, and P is a total barb depth of the barbs.
