Polymer encapsulated colourants by spray drying |
| abstract |
The invention relates to a process of preparing polymer particles which comprise an effective amount of at least one colourant, a polymer matrix and secondary particles distributed within the polymer matrix. The process comprises the following steps: A) Preparation of an emulsion of a polymer formed from a monomer blend in an aqueous phase and Formation of the secondary particles in the aqueous phase; B) Addition to the aqueous phase of an effective colouring amount of at least one colourant; C) Dispersing or dissolving the colourant in the aqueous phase; and D) Subjecting the emulsion to dehydration in a spray-drying unit. |
