| abstract |
The present invention relates to a molded article having a decorative optical effect. Such a molded body has a core-shell in which the shell forms a matrix, the core is essentially solid, has an essentially monodisperse particle size distribution, and the core material and the shell material have different refractive indices. Consists of particles. Such shaped bodies are characterized in that they are obtained by a method in which the core-shell particles are heated to a temperature at which the shell can be melted and the meltable core-shell particles are subjected to mechanical forces. |
