Formkörper aus Kern-Mantel-Partikeln

摘要

The invention relates to moulded bodies with a decorative optical effect. Said bodies consist of core-shell particles, whose shell forms a matrix and whose core is essentially solid and has a substantially mono-disperse size distribution, whereby the refractive indices of the core material and the shell material are different. The moulded bodies are characterised in that they can be obtained by the following method: the core-shell particles are heated to a temperature, at which the shell is fusible and the fusible core-shell particles are subjected to a mechanical force.
