| 摘要 |
The invention relates to a safety label allowing magnetic influences exerted thereon to be visualised by means of magnetic metal particles arranged within a multi-layer construction (12) and to a method of fabricating said safety label, a gel-like function layer (18) containing magnetically responsive metal particles incorporated therein being applied to the support layer (14), at least in specific zones, and surrounded by an adhesive layer (19) arranged on the support layer (14), the gel-like function layer (18) being covered by a covering layer (24) which is provided on a protective layer (28), such that the magnetically responsive metal particles may migrate from the function layer (18) to the covering layer (24) when exposed to a magnetic influence and the proportion of metal particles having passed into the covering layer (24) is visualable.
