Abstract

The invention relates to a composite with inverse thermochromic properties, the composite changing from a colorless into a colored state with increasing temperature. The composite thereby contains a colorant, a developer and a fluxing agent and also an inorganic filler. The invention likewise relates to a composite material which contains a polymer-based matrix into which at least one composite with inverse thermochromic properties is doped. These composite materials are used in the field of sensor technology, solar technology, transport and communications technology and medical technology.
