Abstract
Abstract The invention relates to an antifalsification paper having a security element in the form of a thread or band which consists of a transparent plastic film with an at least partly opaque coating. The security element has at least a first opaque coating and a transparent area bordering on this opaque coating, and information extending from the first opaque coating into the transparent area.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
115 words
An antifalsification paper having at least one security element in the form of threads or bands, said antifalsification paper comprising: at least one transparent plastic film portion; an at least partly opaque coating formed on said transparent plastic film portion defining at least one opaque coating area adjacent to and alternatingly disposed with at least one transparent area; and visually or machine readable characters or patterns for displaying information to be conveyed by said security element, wherein said visually or machine readable characters or patterns are formed on and defined by said adjacent and alternatingly disposed opaque coating and transparent areas whereby said characters or patterns extend from said opaque areas into said transparent areas.
Claim 2
Dependent Claim
115 words
An antifalsification paper having at least one security element in the form of threads or bands, said antifalsification paper comprising: at least one transparent plastic film portion; an at least partly opaque coating formed on said transparent plastic film portion defining at least one opaque coating area adjacent to and alternatingly disposed with at least one transparent area; and visually or machine readable characters or patterns for displaying information to be conveyed by said security element, wherein said visually or machine readable characters or patterns are formed on and defined by said adjacent and alternatingly disposed opaque coating and transparent areas whereby said characters or patterns extend from said opaque areas into said transparent areas.
Claim 3
Dependent Claim
26 words
The antifalsification paper of claim 1 wherein said characters or patterns are defined in said opaque area in the form of gaps in said opaque area.
Claim 4
Dependent Claim
20 words
The antifalsification paper of claim 1 wherein said opaque coating area is formed from a metallization or a metallic-looking ink.
Claim 5
Dependent Claim
33 words
The antifalsification paper of claim 1 wherein said at least partly opaque coating defines said adjacent and alternatingly disposed opaque coating and transparent areas including transparent areas bordering on said opaque coating areas.
Claim 6
Dependent Claim
33 words
The antifalsification paper of claim 1 wherein said opaque coating area is a periodic screen from a geometrical figure and said transparent area is formed by space free of said opaque coating area.
Claim 7
Dependent Claim
50 words
The antifalsification paper of claim 5 wherein said at least partly opaque coating defines a plurality of opaque coating areas alternatingly disposed with a plurality of transparent areas, said opaque coating areas forming a repeating striped pattern disposed at a predetermined angle to a running direction of said security element.
Claim 8
Dependent Claim
18 words
The antifalsification paper of claim 6 wherein said stripped pattern extends at an angle of 0° or 45°.
Claim 9
Dependent Claim
55 words
The antifalsification paper of claim 1 wherein said at least partly opaque coating defines a plurality of opaque coating areas adjacent to and alternatingly disposed with a plurality of transparent areas, said opaque coating areas including a first portion formed from a first opaque coating and a second portion formed from a second opaque coating.
Claim 10
Dependent Claim
33 words
The antifalsification paper of claim 8 wherein said second portion of opaque areas formed from said second opaque coating has the same screen pattern and the same orientation as said first opaque coating.
Claim 11
Dependent Claim
32 words
The antifalsification paper of claim 8 wherein said first portion of opaque areas formed from said first opaque coating is a stripe extending parallel to the running direction of said security element.
Claim 12
Dependent Claim
50 words
The antifalsification paper of claim 8 wherein said first portion of opaque coating areas formed from said first opaque coating comprises two areas disposed parallel to a running direction of said security element and separated by said transparent areas likewise disposed parallel to said running direction of said security element.
Claim 13
Dependent Claim
41 words
The antifalsification paper of claim 8 wherein said first portion of opaque coating areas formed from said first opaque coating and said transparent areas are formed as bars disposed in a checkered arrangement along a running direction of said security element.
Claim 14
Dependent Claim
30 words
The antifalsification paper of claim 8 wherein said second portion of opaque coating areas formed from said second opaque coating has a different inherent color from said first opaque color.
Claim 15
Dependent Claim
27 words
The antifalsification paper of claim 8 wherein said second portion of opaque coating areas formed from said second opaque coating is a metallization or a metallic-looking ink.
Claim 16
Dependent Claim
113 words
A security element to be embedded in an antifalsification paper in the form of a thread or band, said security element comprising: a transparent plastic film; an at least partly opaque coating formed on said transparent plastic film defining at least one opaque coating area adjacent to and alternatingly disposed with at least one transparent area; and visually or machine readable characters or patterns for bearing information to be displayed by said security element, wherein said visually or machine readable characters or patterns are formed on and defined by said adjacent and alternatingly disposed opaque coating and transparent areas whereby said characters or patterns extend from said opaque areas into said transparent areas.
Claim 17
Dependent Claim
113 words
A security element to be embedded in an antifalsification paper in the form of a thread or band, said security element comprising: a transparent plastic film; an at least partly opaque coating formed on said transparent plastic film defining at least one opaque coating area adjacent to and alternatingly disposed with at least one transparent area; and visually or machine readable characters or patterns for bearing information to be displayed by said security element, wherein said visually or machine readable characters or patterns are formed on and defined by said adjacent and alternatingly disposed opaque coating and transparent areas whereby said characters or patterns extend from said opaque areas into said transparent areas.
Claim 18
Dependent Claim
33 words
A security element of claim 15 wherein said at least partly opaque coating defines said adjacent and alternatingly disposed opaque coating and transparent areas including transparent areas bordering on said opaque coating areas.
