The invention relates to microcapsules for which the walls comprise
reaction products of polyisocyanates, guanidine compounds, and optionally
amines, wherein the polyisocyanates have an isocyanurate content of at
least 30% by weight, based on polyisocyanate, and the walls comprise on
average less than 9% by weight, based on the total weight of the
microcapsule.
A invenção relaciona-se aos microcapsules para que as paredes compreendem produtos da reação dos polyisocyanates, dos compostos do guanidine, e opcionalmente dos amines, wherein os polyisocyanates têm um índice do isocyanurate ao menos de 30% pelo peso, baseado no polyisocyanate, e as paredes compreendem na média menos de 9% pelo peso, baseados no peso total do microcapsule.
