Abstract: A process for adjusting the wettability property of a plurality of on-demand activation-type microcapsules of a core and shell structure including the steps of: (a) providing a plurality of microcapsules of a core and shell structure, wherein the shell includes a polymeric matrix containing a certain amount of unreacted functionalizable reactive electrophiles covalently bonded to the surface of the wall of the shell of the microcapsules; and (b) contacting the plurality of microcapsules of step (a) with a certain amount of nucleophiles; wherein the nucleophiles are adapted to react with the electrophiles; and wherein the nucleophiles are adapted to modify the wettability property of the microcapsules' shell structure to a predetermined degree of hydrophilicity or solvent compatibility.

Abstract: Methods for labeling a substrate using a hetero-Diels-Alder reaction are disclosed. The hetero-Diels-Alder reaction includes the reaction of an o-quinone methide (e.g., an o-naphthoquinone methide) with a polarized olefin to form a hetero-Diels-Alder adduct. The o-quinone methide or the polarized olefin can be attached to a surface of a substrate, and the other of the o-quinone methide or the polarized olefin can include a detectable label. The o-quinone methide can conveniently be generated by irradiation of a precursor compound, preferably in an aqueous solution, suspension, or dispersion.
