Composite material comprising core/shell particles

Abstract From the Canadian patent

The invention relates to composite materials having an optical effect containing at least one moulded body which is essentially made of corecovering particles. The covering thereof forms a matrix and the core thereof is essentially solid and has an essentially monodisperse size distribution. There is a difference between the refractive indices of the core material and the covering material and at least one further material which determines the mechanical properties of the composite. The invention also relates to a method for producing composite materials. The inventive materials have a colouring effect, according to the observation angle and freely adjustable mechanical , properties.
