    • The present invention provides in a first aspect a method of manufacture of a security product suitable for use with security articles including security paper such as that used for banknotes, wherein a magnetic metal (10) is deposited on a film of polymeric substrate as the substrate passes through a solution containing the magnetic metal, and a preparatory operation is carried out on a surface of the substrate prior to immersion of the substrate in the solution, characterised in that the preparatory operation ensures that magnetic metal (10) is deposited on the substrate in a chosen pattern such that when the security product is produced from the film by cutting the film, the magnetic metal (10) on the security thread has a specific pattern and provides both a visual discernible security feature and a magnetically detectable security feature. The present invention provides in a second aspect a security product for security paper such as banknotes, the security thread comprising a polymeric substrate, catalytic material covering at least a portion of one surface of the polymeric substrate, and a layer of electrolessly deposited magnetic metal (10) covering at least a portion of the catalytic material with a depth in the range 0.01-3.0 mu m.
    • 本发明在第一方面提供了一种制造安全产品的方法,该安全产品适用于包括诸如用于纸币的安全纸的安全用品,其中磁性金属(10)沉积在聚合物基材的膜上作为基材 通过含有磁性金属的溶液,并且在将衬底浸入溶液之前在衬底的表面上进行准备操作,其特征在于,准备操作确保磁性金属(10)沉积在衬底上 以选择的图案,使得当通过切割胶片从胶片制造安全产品时,安全线上的磁性金属(10)具有特定的图案并且提供可视识别的安全特征和可磁性可检测的安全特征。 本发明在第二方面提供一种用于诸如纸币的安全纸的安全产品,安全线包括聚合物基材,覆盖聚合物基材的一个表面的至少一部分的催化材料和无电沉积磁性金属层 10)覆盖至少一部分催化材料,深度在0.01-3.0μm的范围内。
