A process for manufacturing microcapsules |
abstract |
A process for manufacturing microcapsules comprises in situ polymerization of a urea or melamine formaldehyde polymer precursor material in an aqueous manufacturing vehicle in the presence of one of a range of specified acrylic acid-alkyl methacrylate copolymers containing a critical proportion of alkyl methacrylate. The resulting capsules may be used in pressure-sensitive copying materials. |
