ABSTRACT:
In microcapsules with a polymeric capsule wall, the polymer of the capsule wall comprises thermolabile predetermined breaking points in the form of hexamethylenetetramine or acetaldehyde ammonia derivatives in order to facilitate release of the capsule contents (various active substances, such as example, dyes, medicaments, developers, curing agents, flameproofing agents) in a specific manner by exposure to heat.
