TWO STAGE METHODS FOR PROCESSING ADHESIVES AND RELATED COMPOSITIONS

The present invention relates to a method of forming an adhesive, the method comprising:providing a composition including at least one monomer having one or more ethylenically unsaturated bonds, a first actinic radiation initiator, and a second actinic radiation initiator, wherein the second initiat...

Beschreibung
Zusammenfassung:	The present invention relates to a method of forming an adhesive, the method comprising:providing a composition including at least one monomer having one or more ethylenically unsaturated bonds, a first actinic radiation initiator, and a second actinic radiation initiator, wherein the second initiator is non-photoactive at activation wavelength(s) of the first initiator;at least partially polymerizing the composition to form a pre-adhesive by exposing the composition to radiation having wavelengths corresponding to the activation wavelength(s) of the first initiator;at least partially crosslinking the pre-adhesive composition to thereby form the adhesive by exposing the pre-adhesive composition to radiation having wavelengths corresponding to the activation wavelength(s) of the second initiator;wherein at least one of the first and the second initiators is a polymerizable monomer containing a photoinitiator moiety.
