Dental compositions

Claim 2

A dental composition comprising a combination of 8 to 92% by weight of liquid acid phosphates obtained by replacing one or two hydrogen atoms of orthophosphoric acid with alcohols having 3 to 13 carbon atoms and being essentially insoluble in water, 92 to 8% by weight of at least one of reactive multivalent metallic salts selected from the group consisting of oxides, hydroxides, basic salts and silicates of alkaline earth metals, aluminium of heavy metals, and 50 to 5% by weight of at least one of sparing soluble fluorides, silicofluorides, titanium fluorides and zirconium fluorides serving as a reaction accelerator based on the weight of said acid phosphates, said compounds being permitted to react with each other such that they are cured at room temperature.

Claim 3

A dental composition according to claim 1, including further at least one of resins having an effective carboxyl group in amounts of less than 80% by weight of the total components.

Claim 4

A dental composition composing a combination of 8 to 92% by weight of acid components consisting of 0.5 to 60% by weight of liquid acid phosphates obtained by replacing one or two hydrogen atoms of orthophosphoric acid with alcohols having 3 to 13 carbon atoms and being essentially insoluble in water and the remainder being at least one of mono- or more- valent liquid organic carboxylic acids having 6 or more carbon atoms and being liquid at room temperature, 92 to 8% by weight of at least one of reactive multivalent metallic salts selected from the group consisting of oxides, hydroxides, basic salts and silicates of alkaline earth metals, aluminium and heavy metals, and at least one of sparing soluble fluorides, silicofluorides, titanium fluorides and zirconium fluorides which serve as a reaction accelerator and are added in amounts of less than 50 to 50% by weight of said acid phosphates, said compounds being permitted to react with each other such that they are cured at room temperature.

Claim 5

A dental composition composing a combination of 8 to 92% by weight of acid components consisting of 0.5 to 60% by weight of liquid acid phosphates obtained by replacing one or two hydrogen atoms of orthophosphoric acid with alcohols having 3 to 13 carbon atoms and being essentially insoluble in water and the remainder being at least one of mono- or more- valent liquid organic carboxylic acids having 6 or more carbon atoms and being liquid at room temperature, 92 to 8% by weight of at least one of reactive multivalent metallic salts selected from the group consisting of oxides, hydroxides, basic salts and silicates of alkaline earth metals, aluminium and heavy metals, and at least one of sparing soluble fluorides, silicofluorides, titanium fluorides and zirconium fluorides which serve as a reaction accelerator and are added in amounts of less than 50 to 50% by weight of said acid phosphates, said compounds being permitted to react with each other such that they are cured at room temperature.

Claim 6

A dental composition according to claim 3, including further at least one of resins having an effective carboxyl group in amounts of less than 80% by weight of the total components.

Claim 7

A dental composition comprising a combination of 8 to 92% by weight of acid components consisting of 0.5 to 60% by weight of liquid acid phosphates obtained by replacing one or two hydrogen atoms of orthophosphoric acid with alcohols having 3 to 13 carbon atoms and being essentially insoluble in water and the remainder being at least one of mono- or more- valent liquid organic carboxylic acids having 6 or more carbon atoms and being liquid at room temperature, 92 to 8% by weight of at least one of reactive multivalent metallic salts selected from the group consisting of oxides, hydroxides, basic salts and silicates of alkaline earth metals, aluminium and heavy metals, at least one of di- or more- valent solid organic carboxylic acids having a melting point of lower than 200° C. or liquid organic carboxylic acids having 5 or less carbon atoms which are added in amounts of less than 10% by weight of said acid components, and at least one of sparing soluble fluorides, silicofluorides, titanium fluorides and ziroconium fluorides which are added as a reaction accelerator in amounts of 50 to 5% by weight based on the quantities of said acid phosphates, said compounds being permitted to react with each other such that they are cured at room temperature.

Claim 8

A dental composition comprising a combination of 8 to 92% by weight of acid components consisting of 0.5 to 60% by weight of liquid acid phosphates obtained by replacing one or two hydrogen atoms of orthophosphoric acid with alcohols having 3 to 13 carbon atoms and being essentially insoluble in water and the remainder being at least one of mono- or more- valent liquid organic carboxylic acids having 6 or more carbon atoms and being liquid at room temperature, 92 to 8% by weight of at least one of reactive multivalent metallic salts selected from the group consisting of oxides, hydroxides, basic salts and silicates of alkaline earth metals, aluminium and heavy metals, at least one of di- or more- valent solid organic carboxylic acids having a melting point of lower than 200° C. or liquid organic carboxylic acids having 5 or less carbon atoms which are added in amounts of less than 10% by weight of said acid components, and at least one of sparing soluble fluorides, silicofluorides, titanium fluorides and ziroconium fluorides which are added as a reaction accelerator in amounts of 50 to 5% by weight based on the quantities of said acid phosphates, said compounds being permitted to react with each other such that they are cured at room temperature.
