ABSTRACT:
A process for forming photosensitive microcapsules having discrete capsule walls comprising the steps of forming an emulsion of an oily core material in a continuous aqueous phase containing a carboxyvinyl polymer and enwrapping particles of the oily core material in an amine-formaldehyde condensation product produced by in situ condensation of an amine and formaldehyde wherein the carboxyvinyl polymer comprises a crosslinked polymer of acrylic acid is disclosed.
