Beschreibung
Zusammenfassung:	In a first aspect, the present invention relates to an encapsulated organic pigment comprising of an organic pigment as core material and a material capable of forming microcapsules as shell material, wherein the particle size of the encapsulated pigment (core-shell-product) is in the range from 50 nm to 500 µm and the particle size distribution D 90 is < 100 µm. Selon un premier aspect, la présente invention concerne un pigment organique encapsulé comprenant un pigment organique en tant que matériau de cœur et un matériau pouvant former des microcapsules en tant que matériau d'écorce, la taille de particule du pigment encapsulé (produit cœur-écorce) étant située dans la plage allant de 50 nm à 500 µm et la distribution de taille de particule D 90 étant < 100 µm.
