A curable composition comprises at least one monomer comprising at least one (meth)acryl group and a photoinitiator system. The photoinitiator system comprises at least one Type II photoinitiator and at least one cyclic β-diketone represented by the formula (I) or a tautomer thereof. Rrepresents an organic moiety having at least one free-radically polymerizable group. Each Rindependently represents H or an aliphatic group having from 1 to 12 carbon atoms, and up to two of oxygen and sulfur atoms, n represents 1, 2, or 3.

Curable compositions and methods of using the same

Disclosed herein is a thioester-containing (meth)acrylate compound comprising at least two thioester moieties and at least 2 (meth)acrylate moieties and a method for making such compounds. These compounds can be used in (meth)acrylic resins as a crosslinking agent. Upon exposure to a nucleophilic solvent, cured (meth)acrylic resins derived from these thioester-containing (meth)acrylate compounds can be degraded.

Degradable crosslinkers for (meth)acrylic resins and methods thereof

An adhesive composition is described comprising at least one cyclic imide monomer comprising an unsaturated carbonyl. The adhesive composition is a polymerizable composition or a polymerized composition. The polymerizable adhesive composition may comprise at least one monomer, oligomer, polymer, or a combination thereof comprising ethylenically unsaturated groups and/or an epoxy resin. The cyclic imide monomer may comprise an imide group with an α, β-unsaturated carbonyl in a heterocyclic ring wherein the ring comprises at least 6 covalently bonded atoms. Also described are methods of forming an adhesive coated substrate and articles.

Adhesives comprising cyclic imide addition-fragmentation and adhesion agents

A dental composition is provided. The dental composition includes at least one monomer comprising at least two ethylenically unsaturated groups; and an addition-fragmentation agent comprising at least one cyclic imide monomer comprising an α, β-unsaturated carbonyl.

Dental compositions

Curable compositions comprise at least one (meth)acrylate monomer; silver; and a photoinitiator system. The photoinitiator system comprises at least one cyclic β-diketone represented by the formula (I) or a tautomer thereof, wherein: Rrepresents H or an organic moiety having from 1 to 32 carbon atoms and optionally 1 to 12 heteroatoms selected from O, N, and combinations thereof; each Rindependently represents H or an aliphatic group having from 1 to 12 carbon atoms, and up to two of oxygen and sulfur atoms; and n represents 1, 2, or 3; and at least one Type II photoinitiator. Methods of making and using the compositions are also disclosed.
