  • Publication number: 20110180207
    Abstract: The invention relates to a process for forming a cured, partially cured or uncured thermosetting material, comprising: an irradiation step wherein the thermosetting material is exposed to electromagnetic radiation which to a significant extent is within the near-infrared range in such a way that the temperature of the irradiated thermosetting material is brought to between 40° C. and 400° C., and a forming step wherein the irradiated thermosetting material is brought into a desired shape, whereby the forming step is executed during and/or subsequent to the irradiation step. The invention also relates to an apparatus for carrying out the said process and to a thermosetting material.

  • Publication number: 20080031909
    Abstract: Cosmetic materials, e.g., sunscreen agents are encapsulated by means of a compound of the formula (I) where X is O or NR5; EWG is an electron-withdrawing group; R1, R2, R3, R5 are equal to an H, alykl, cycloalkyl, aryl, or heterocyclic group; or R1, R2 and R5 or R1, R2 and R3 together form a heterocyclic group; and wherein at least one NH or NH2 group, attached to an electron-attracting atom or to an atom that is connected to electron-attracting atom or group such as oxygen, nitrogen and sulphur, is present.

  • Publication number: 20070092726
    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 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 NR5; EWG is an electron-withdrawing group; R1, R2, R3, R5 are equal to an H, alkyl, cycloalkyl, aryl of heterocycl group; and R1, R2, and R5 or R1, R2, and R3 may together form a heterocyclic group.
