1. A kit for bonding a composite resin to enamel, dentin or metal, comprising:
- a single-solution formulation which comprises not more than two monomers and an initiator consisting of a photoinitiator, wherein a first of the two monomers is a carboxylic acid monomer and the second of the two monomers is a diluent monomer wherein polymerization of said monomers forms a bond having a shear bond strength of at least 20 MPa; and
a composite resin.

Abstract
Single-solution adhesive resin formulations are made of predominantly dimethacrylates or diacrylates containing (predominantly) two carboxyl groups and a functionalized methacrylate or acrylate diluent monomer. A novel light-activated initiator can be used for photopolymerization of such adhesives.
