Abstract
A dental adhesive comprising a (meth)acryloylaminoalkyl carboxylate of the formula ##STR1## in which R.sup.1 represents hydrogen or methyl; R.sup.2 represents methylene or ethylene; and R.sup.3 represents hydrogen, methyl, or ethyl; and at least one of an initiator, a non-toxic solvent, and a filler. The dental adhesive is useful to effect a strong adhesive bonding of dental materials to collagen-containing materials.
Claims19
A dental adhesive consisting of the following ingredients:
- (1) at least one (meth)acryloylaminoalkyl carboxylate of the formula:
- ##STR12## in which R.sup.1 represents hydrogen or methyl;
- R.sup.2 represents methylene or ethylene;
- and
- R.sup.3 represents hydrogen, methyl or ethyl;
- and at least one of the following ingredients:
- (2) about 0.01 to 2 parts by weight initiator relative to 100 parts by weight of polymerizable compounds in the dental adhesive;
- (3) a non-toxic solvent;
- or
- (4) a filler;
- and optionally at least one of the following ingredients:
- (5) a polymerization reaction accelerator;
- (6) a cross-linkable (meth)acrylic acid ester compound containing two or more polymerizable (meth)acryl groups;
- or
- (7) an aliphatic mono- or dialdehyde.
In the application of an adhesive material to a collagen-containing material, the improvement wherein said adhesive material comprises a (meth)acryloylaminoalkyl carboxylate of the formula ##STR14## in which R.sup.1 denotes hydrogen or methyl,
- R.sup.2 denotes methylene or ethylene and
- R.sup.3 represents hydrogen, methyl or ethyl.
