光学可变安全线和条
Abstract:
本发明发现了安全线或条。所述安全线或条包含i)在不同视角下赋予第一不同色彩印象的第一光学可变层(1,8)，ii)在不同视角下赋予第二不同色彩印象的第二光学可变层(2,9)，iii)具有匹配第一或第二光学可变层在第一视角下的色彩印象的色彩的第一色彩恒定层(4,6)，iv)具有匹配第一或第二光学可变层在第二视角下的色彩印象的色彩的第二色彩恒定层(5,7)，和v)基质，其中第一光学可变层、第二光学可变层、第一色彩恒定层和第二色彩恒定层从安全线或条的一侧共同地可见。
Abstract(English):

The present invention discovers a security thread or stripe. The security thread or stripe comprises i) a first optically variable layer (1,8) imparting a first different color impression at different viewing angles, ii) a second optically variable layer (2,9) imparting a second different color impression at different viewing angles, iii) a first color constant layer (4,6) having a color matching the color impression of the first or second optically variable layer at a first viewing angle, iv) a second color constant layer (5,7) having a color matching the color impression of the first or second optically variable layer at a second viewing angle, and v) a substrate, wherein the first optically variable layer, the second optically variable layer, the first color constant layer and the second color constant layer are jointly visible from one side of the security thread or stripe.
