The present invention provides an antibacterial artificial nail composition which can form a cured article having an antibacterial effect by applying the composition on a surface of a natural nail or an artificial nail and polymerizing the composition, using an artificial nail technique of forming a cured article on a natural nail or an artificial nail. Disclosed is an antibacterial artificial nail composition comprising (A) a compound having at least one radical polymerizable unsaturated double bond and an antibacterial group in the molecule and/or (B) an antibacterial filler, (C) a compound having at least one radical polymerizable unsaturated double bond in the molecule, and (D) a polymerization initiator.

Antibacterial artificial nail composition

The present invention provides an artificial nail composition which can easily impart a special appearance to the tip of the finger, and which is an artificial nail material coated on a natural or artificial nail, and is used by coating on the surface of a natural or artificial nail followed by polymerization and, more particularly, an artificial nail composition which is vivid and has a natural color tone having a transparent sensation, that cannot be achieved by a conventionally used artificial nail composition containing an organic and/or inorganic colorant utilizing absorption and/or a scattering phenomenon of light, and imparts special appearance by an interference color.

Artificial nail composition having excellent appearance

An object of the present invention is to provide an artificial nail composition which can improve adhesion between a natural nail and an artificial nail, and also can suppress exfoliation or detachment. The artificial nail composition comprises:

Artificial nail composition having improved adhesion property

The present invention provides a dental self-adhesive resin cement having clinically-acceptable adherability for various adherends without pre-treatment with primers. Specifically, there is provided the dental self-adhesive composite resin cement comprising:

Two-paste type dental self-adhesive resin cement

The present invention provides a one-component dental adhesive composition which can exhibit excellent adhesion to both materials of a dental ceramics and an organic composite containing an inorganic compound, and is excellent in can-stability. More particularly, the present invention provides a one-component dental adhesive composition comprising 1 to 60 parts by weight of (a) a silane coupling agent, 1.0 to 20.0 parts by weight based on 100 parts by weight of the (a) component of (b) an acidic group-containing polymerizable monomer, and 28 to 99 parts by weight of (c) a volatile organic solvent.

Single component dental composition containing silane coupling agent and acidic group containing polymerizable monomer

Disclosed is a one-pack type dental adhesive composition comprising:

One-pack type dental adhesive composition

An object of the present invention is to provide a one-pack type dental adhesive composition which can exhibit excellent adhesion to any material, for example, dental ceramics, organic composites containing inorganic compounds, dental noble metals and dental non-noble metals, and also has excellent storage stability. Disclosed is a one-pack type dental adhesive composition comprising a silane coupling agent as a component (a), an acidic group-containing polymerizable monomer as a component (b), a sulfur atom-containing polymerizable monomer as a component (d), and other components.

An object of the present invention is to provide a paste-type cement composition which while retaining adhesion to tooth substance, biocompatibility, surface curability and fluorine sustained-releasability which are the characteristics derived from the conventional glass ionomer cement, reduces water sensitivity which is shortcoming of the conventional glass ionomer cement, enables simple mixing operation, does not adversely affect on the various properties of a cured cement depending on a difference in operators or a skill degree, and can afford various stable properties. There is provided a two paste-type glass ionomer cement comprising a resin-based paste containing a hydrophobic polymerizable monomer and a polymer of acidic group-containing polymerizable monomers which are insoluble to each other, and a water-based paste containing a hydrophilic polymerizable monomer and water which are soluble to each other, in which an acid reactive filler is contained in at least one of pastes.

Two paste-type glass ionomer cement

To provide a dental prosthetic material having processing characteristics and operating characteristics, which are not recognized in a conventional dental material. A biorestorative material which is a rubber elastic material having a shear modulus of 1.0-9.99 E+4 Pa to 1.0-9.99 E+9 Pa and a rubber hardness of 1 to 90, wherein a Knoop hardness can be 10 or more after polymerization.

Dental elastic restorative material and method for production of dental

The present invention relates to a curable composition in which polymer and monomer which is neither soluble nor swellable (able to swell) in the polymer are mixed homogeneously. More particularly, the present invention relates to a curable composition, in which polymer and urethane metha(acrylate) which is neither soluble nor swellable in the polymer are mixed homogeneously. The present invention also relates to a cured composition of the curable composition.

Composition containing urethane (metha)acrylate in polymer

The present invention provides a dental curable material suitable for a production of an artificial teeth having a strong toughness, wear resistance, transparency and moldability, which comprises a silane-treated silica uniformely dispersed in urethane (meth)acrylate (a): said silica has a 1 to 85 nm, with at least one silane compound represented by the formula (1):
