Compositions that are curable by free radical redox reactions are disclosed. Free radical curing reactions between polythiols and polyalkyenyls are initiated by the reaction of metal complexes and organic peroxides. The compositions are useful as sealants.

Dual cure sealants

One embodiment is a pressure sensitive adhesive label or tape that comprises a facestock, and a pressure sensitive adhesive composition disposed on the facestock and the pressure sensitive adhesive composition includes a product made from reacting an epoxidized naturally occurring oil or fat with a dimer acid. Another embodiment of the invention is a method that comprises reacting an epoxidized naturally occurring oil or fat with a dimer acid to form a PSA precursor; coating the PSA precursor onto a carrier and curing the PSA precursor via UV radiation to form a pressure sensitive adhesive.

Pressure sensitive adhesives based on renewable resources, UV curing and related methods

Methods and/or systems for printing or otherwise evincing temporary indicia on media with disappearing inks are described along with suitable disappearing ink formulations and media constructions for executing the same. In particular embodiments, the methods and/or systems described employ a plurality of disappearing inks with different disappearing rates. In one embodiment, a barrier layer that is selectively used to cover a major surface of the media is employed to substantially block or otherwise regulate a rate of phase transitions (e.g., evaporation and/or sublimation) experienced by ink borne by the media.
