Abstract
An energy-sensitive (e.g., thermal, radiation or photosensitive) initiator, curative, and/or catalytic salt that has an anion comprising a tris-(highly fluorinated alkylsulfonyl)methide, tris-(fluorinated arylsulfonyl)methide, bis-(highly fluorinated alkyl)sulfonyl imide, bis-(fluorinated aryl)sulfonyl imide, mixed aryl- and alkylsulfonyl imides and methides and any combinations thereof, has improved solubility in organic solvents, exhibit minimal corrosiveness when coatings and adhesives are prepared using the initiator, curative and/or catalytic salts, generates a highly reactive initiator, curative, and/or catalyst upon activation by energy.
Claims27
An energy activatable salt wherein the energy activatable salt has
- (1) a cation comprising at least one of (a) an organometallic cation, wherein the organometallic cation comprises (i) substituted or unsubstituted aromatic compounds based on arene or cyclopentadienyl ligands and, (ii) a transition metal atom, (b) an I-, P-, C- and S-centered organic onium cation, or (c) a mixture thereof, and
- (2) a sufficient number of an anion to neutralize the charge of the cation, wherein the anion comprises a tris-(highly fluorinated alkylsulfonyl)methide, tris-(fluorinated arylsulfonyl)methide, bis-(highly fluorinated alkylsulfonyl)imide, bis-(fluorinated arylsulfonyl)imide, mixed aryl- and alkylsulfonyl imides and methides and any combinations thereof and
- with the proviso that the salt is not a diazonium salt, an ammonium salt, or a simple metal salt.
