Abstract

The invention relates to doping capsules which have a substance which displays a decreasing transparency with increasing temperature within a defined temperature range due to physicochemical interactions with the polymer matrix to be doped. Likewise, the invention relates to composite systems which have a polymer matrix doped with the doping capsules. The capsules according to the invention are used for sun protection or heat reflection.
