Patent number: 9694618Abstract: The invention relates to a method for producing a multilayer element (100), and also to a multilayer element (100) produced by said method. On and/or in a carrier ply (1) a decorative ply (3) is formed. The decorative ply (3) has a first region (8) and a second region (9). Viewed perpendicular to the plane of the carrier ply (1), the decorative ply (3) has in the first region (8) a first transmittance and in the second region (9) a second transmittance greater in comparison to the first transmittance. A layer (5) to be structured and a photoactivatable resist layer are disposed on the first side (11) of the carrier ply (1). On exposure of the resist layer through the decorative ply (3), the decorative ply (3) serves as an exposure mask. The at least one layer (5) to be structured and the resist layer are structured in register to one another by means of structuring operations synchronized with one another.Type: GrantFiled: February 21, 2014Date of Patent: July 4, 2017Assignee: LEONHARD KURZ STIFTUNG & CO.

Publication number: 20160375714Abstract: The invention concerns a process for producing a film element having mutually registered metallic layers (11, 16) and a film element which can be produced by such a process. A first metallic layer (11) provided on a first surface of a flexible single-layer or multi-layer carrier film (10) and a masking layer (13) provided on the second surface of the carrier film (10), opposite to the first surface, are structured in accurate register relationship with each other by means of mutually synchronised structuring procedures.

Publication number: 20160167422Abstract: An optically variable element has first and second diffraction gratings which are high-frequency and therefore act reflectively into the zero diffraction order. Either a first color is generated by the first diffraction grating at a particular angle of rotation and a particular angle of illumination and simultaneously a second color, different from the first color, is generated by the second diffraction grating or a visible color is generated essentially only by the first diffraction grating at a first angle of rotation and a visible color is generated essentially only by the second diffraction grating at a second angle of rotation.Type: ApplicationFiled: May 6, 2014Publication date: June 16, 2016Inventors: Ludwig Brehm, Sebastian Mader, Andreas Schilling, Wayne Robert Tompkin, Harald Walter
