Abstract
Abstract A security element in the form of a thread or strip to be embedded in security documents such as bank notes, checks, bonds, identity cards, credit cards or the like, having characters, patterns, etc., that are readable by transmitted light to the naked eye and/or by machine. The security element consists of a transparent plastic film having an opaque coating extending over the element with recesses in the form of the characters and patterns to be introduced. The security element also contains, in areas congruent with the recesses, coloring and/or luminescent substances which cause the characters and/or patterns to differ from the security document and from the opaque coating by color contrast under suitable light conditions.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
80 words
A security element in the form of a thread or strip to be embedded in security documents, wherein the security element comprises a transparent plastic film having an opaque coating extending over the element with recesses corresponding to patterns to be introduced and, in areas congruent with the recesses, at least one of coloring substances and luminescent substances which cause the patterns to differ from the security element and from the opaque coating by color contrast under suitable light conditions.
Claim 2
Dependent Claim
80 words
A security element in the form of a thread or strip to be embedded in security documents, wherein the security element comprises a transparent plastic film having an opaque coating extending over the element with recesses corresponding to patterns to be introduced and, in areas congruent with the recesses, at least one of coloring substances and luminescent substances which cause the patterns to differ from the security element and from the opaque coating by color contrast under suitable light conditions.
