Claims13
A or curable composition comprising:
- (a) at least one multi-functional Michael donor;
- (b) at least one multi-functional Michael acceptor;
- and
- (c) and at least one reaction promoter,
- wherein at least a portion of the reaction promoter is present on at least one surface to which compositions are applied.
A curable composition comprising:
- (a) at least one multi-functional Michael donor;
- (b) at least one multi-functional Michael acceptor;
- and
- (c) and at least one reaction promoter,
- wherein the at least one reaction promoter is selected from the group consisting of:
- at least one catalyst, co-catalyst and acid scavenger.
A laminate comprising:
- at least two substrates in contact with the reaction product of (a) at least one multi-functional Michael donor and (b) at least one multi-functional Michael acceptor, wherein at least one reaction promoter is present on the surface of least one of the substrates prior to lamination.
An article wherein at least a portion of its surface is in contact with a reaction product of (a) at least one multi-functional Michael donor and (b) at least one multi-functional Michael acceptor, wherein a reaction promoter is present on the surface prior to the reaction of (a) and (b)
A substrate comprising:
- at least one reaction promoter included into the substrate during manufacture of the substrate, or coating the substrate with a mixture including at least one reaction promoter, or by subjecting the substrate to at least one process that generates or includes a reaction promoter on its surface.
An ink, primer, or coating for substrates which comprises at least one reaction promoter which promotes or catalyzes the reaction of a Michael donor and acceptor.
An ink, primer or coating which comprises at least one co-catalyst for the reaction of a Michael donor and acceptor.
An ink, primer, or coating for substrates which comprises at least one acid scavenger.
