摘要 |
The invention therefore comprises a security substrate ( 11 ) comprising a fibrous substrate and a security device ( 10 ) The security device ( 10 ) comprises an at least partially light transmissive polymeric carrier layer bearing a first security feature and the substrate being provided with a second security feature. The first and second security features are formed and located relative to each other such that, when one side of the security substrate ( 11 ) is viewed in transmitted light the first and second security features visually combine to form a first composite image, which is not seen in reflected light. |
