ABSTRACT:
Microcapsules which can be prepared at low temperatures contain walls composed of the product of an interface polyaddition and/or interface polycondensation reaction between a hydroxylamine and at least one component which is reactive with amino and alcohol groups. These microcapsules are advantageously used in the production of carbonless copying paper and thermal paper.
