<p>A flexible laminate, comprising: the light-active second layer acts without external energizing to change the properties of incident light such that the light reflected by this layer has signaling properties; a first layer serving as carrier layer; a light-active second layer situated on an outer surface of this laminate; and a permanent magnetic third layer for releasable magnetic attachment of the laminate to a ferromagnetic surface. The laminate has the feature that the light-active second layer acts without external energizing to change the properties of incident light such that the light reflected by this layer has signaling properties.</p> |
