Abstract
Abstract A primer composition for providing bonding between collagen containing materials, including dentin, bones and leather, and acrylate resins is disclosed comprising a monomer of the acrylate type containing reactive hydrogen and an aldehyde group containing compound. The combination may be made as a physical mixture or a chemical reaction product.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
34 words
A composition comprising an aldehyde, an olefinically unsaturated monomer containing active hydrogen and, optionally, water and/or a toxicologically acceptable organic solvent for use to improve adhesion between collageneous materials, in particular dentin, and resins.
Claim 2
Dependent Claim
34 words
A composition comprising an aldehyde, an olefinically unsaturated monomer containing active hydrogen and, optionally, water and/or a toxicologically acceptable organic solvent for use to improve adhesion between collageneous materials, in particular dentin, and resins.
Claim 3
Dependent Claim
21 words
A composition according to claim 1, characterized in that the aldehyde has 1 to 20, preferably 1 to 10 carbon atoms.
Claim 4
Dependent Claim
13 words
A composition according to claim 2, characterized in that the aldehyde is aliphatic.
Claim 5
Dependent Claim
29 words
A composition according to any of claims 1 to 3, characterized in that the aldehyde group, the olefinically unsaturated group and the active hydrogen are comprised in one compound.
Claim 6
Dependent Claim
32 words
A composition according to claim 3, characterized in that the aldehyde is selected from formaldehyde, a compound which is able to release formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde and glutaraldehyde, and preferably is glutaraldehyde.
Claim 7
Dependent Claim
23 words
A composition according to any of claims 1 to 5, characterized in that the monomer is an ester of acrylic or methacrylic ester.
Claim 8
Dependent Claim
24 words
A composition according to any of claims 1 to 6, characterized in that the active hydrogen is an OH-, NH- or NFi 2 -group.
Claim 9
Dependent Claim
27 words
An adhesion promoting agent for application on collageneous substances, particularly dentin, characterized in that it comprises a composition as defined in any of claims 1 to 7.
Claim 10
Dependent Claim
15 words
An agent according to claim 8, characterized in that it comprises glutaraldehyde and hydroxyethyl methacrylate.
Claim 11
Dependent Claim
37 words
A process for preparing an agent according to claim 8 or 9, characterized in that an aldehyde is mixed with an olefinically unsaturated monomer containing active hydrogen and, optionally, water and/or a toxicologically acceptable volatile organic solvent.
Claim 12
Dependent Claim
37 words
Use of an agent according to claim 8 or 9 to promote adhesion of collageneous material to itself or to a curable composition based on an olefinically unsaturated monomer, preferably between dentin and a dental filling material.
Claim 13
Independent Claim
49 words
A method for improving the bonding capacity of collageneous material to itself or to a curable composition based on an olefinically unsaturated monomer, characterized in that the surface of the collageneous material is treated with an aldehyde and simultaneously or subsequently with an olefinically unsaturated monomer containing active hydrogen.
Claim 14
Independent Claim
49 words
A method for improving the bonding capacity of collageneous material to itself or to a curable composition based on an olefinically unsaturated monomer, characterized in that the surface of the collageneous material is treated with an aldehyde and simultaneously or subsequently with an olefinically unsaturated monomer containing active hydrogen.
Claim 15
Dependent Claim
22 words
A method according to claim 12, characterized in that the surface is treated with an agent according to claim 8 to 9.
