Abstract

In order to create novel security features in secure and/or valuable documents, a polymer layer composite, which has at least two polymer layers that are bonded to each other in a material fit is provided. At least one surface is printed with an absorbing printed layer within a visible region in and/or on the composite located on a polymer layer of the composite. The absorbing printed layer forms at least one printed region, and all printed regions of the printed surface of the polymer layer have a total surface area of at least 50% and not more than 95%.

said at least one surface being one of;

printed with said print layer on one of said at least two polymer layers and having at least one free surface region in a form of a window and that information is printed in said at least one free surface region; and

printed with said print layer on a first polymer layer of said at least two polymer layers and having at least one free surface region in a form of a window and that information is printed on at least one of said surfaces of a second polymer layer of said at least two polymer layers so that the information is visible through said at least one free surface region on said first polymer layer.

49. The polymer laminate according to claim 48, wherein a plurality of said print regions on said printed surface form at least one cohesive and extensive print region.

50. The polymer laminate according to claim 48, wherein said information includes a piece of information selected from the group consisting of characters and a barcode.

51. The polymer laminate according to claim 48, wherein said free surface regions in which said surface is not printed are present on said printed surface on said polymer layer and wherein said free surface regions together form said information.
