Abstract
The invention relates to a process for forming capsules comprising the steps of: (1) forming a solution of an amino compound (1) in a solvent; (2) forming a dispersion of a core material in the solution;(3) depositing the amino compound as a resin M upon the surface of the core material to form capsules; and (4) optionally hardening and/or recovering the capsules, whereby steps
(1) and (2) are executed in either order or simultaneously, and wherein amino compound (1) has the following formula (I) where: X is O or NRs; EWG is an electron-withdrawing group; R1, R2, R3, Rs are equal to an H, alkyl, cycloalkyl, aryl of heterocyclic group; and R1, R2, and Rs or R1, R2, and R3 may together form a heterocyclic group.
