Abstract
(DE)
Vorgeschlagen werden Mikrokapseln, umfassend (a) einen Kern, enthaltend mindestens einen Wirkstoff, und (b) eine Kapselwand, wobei die Kapselwand aus mindestens drei Polymerschichten besteht und mindestens eine der Polymerschichten aus einem ersten Phenolharz besteht, wobei das erste Phenolharz 3 bis 50 Gew.% Gruppierungen umfasst, die sich von mindestens einem aromatischen Polyol ableiten und mindestens eine weitere der Polymerschichten aus einem zweiten Phenolharz besteht, wobei das zweite Phenolharz 3 bis 50 Gew.% Gruppierungen umfasst, die sich von mindestens einem Triphenol ableiten.
(EN)
The present invention relates to microcapsules comprising (a) a core, containing at least one active ingredient, and (b) a capsule wall, the capsule wall consisting of at least three polymer layers and at least one of the polymer layers consisting of a first phenol resin, the first phenol resin comprising 3 to 50 wt% of groupings that derive from at least one aromatic polyol, and at least one further of the polymer layers consisting of a second phenol resin, the second phenol resin comprising 3 to 50 wt% groupings that derive from at least one triphenol.
(FR)
L’invention concerne des microcapsules, comprenant (a) un noyau, contenant au moins un principe actif, et (b) une paroi de capsule, cette dernière étant constituée d’au moins trois couches polymères, au moins une de ces couches polymères étant constituée d'une première résine phénolique comprenant 3 à 50 % en poids de groupements dérivés d'au moins un polyol aromatique et au moins une autre de ces couches polymères étant constituée d'une deuxième résine phénolique comprenant 3 à 50 % en poids de groupements dérivés d'au moins un triphénol.
