Abstract
Abstract The invention concerns an imprintable, flexible, synthetic support bearing at least one authentication or security mark. This support comprises: a substrate of synthetic material at least one mark on at least one face of the support and consisting of at least one layer of a composition altering the substrate opacity, at least one layer of an imprintable pigment composition deposited on the face bearing the mark and optionally also on the substrate face without the mark, the mark being barely or not at all visible in reflected light and perfectly visible in transmitted light. Application to the security of synthetic paper.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
93 words
An imprintable, flexible synthetic support bearing at least one authentication or security mark, said support comprising: a substrate of synthetic material, at least one mark deposited or imprinted on at least one face of the substrate, said mark comprising at least one composition altering the substrate opacity, at least one layer of an imprintable pigment composition covering the mark, said layer being deposited on the face with the mark and optionally on the face of the substrate without marking, the mark being barely visible in reflected light and perfectly visible in transmitted light.
Claim 2
Dependent Claim
93 words
An imprintable, flexible synthetic support bearing at least one authentication or security mark, said support comprising: a substrate of synthetic material, at least one mark deposited or imprinted on at least one face of the substrate, said mark comprising at least one composition altering the substrate opacity, at least one layer of an imprintable pigment composition covering the mark, said layer being deposited on the face with the mark and optionally on the face of the substrate without marking, the mark being barely visible in reflected light and perfectly visible in transmitted light.
Claim 3
Dependent Claim
12 words
Support according to claim 1, wherein the marking is monochromatic or polychromatic.
Claim 4
Dependent Claim
20 words
Support according to claim 1, wherein the opacity-altering composition contains at least one mineral filler and at least one binder.
Claim 5
Dependent Claim
19 words
Support according to claim 1, wherein the opacity-altering composition contains at least one soluble dye or a pigment colorant.
Claim 6
Dependent Claim
13 words
Support according to claim 1, wherein the opacity-altering composition contains a fluorescing agent.
Claim 7
Dependent Claim
15 words
Support according to claim 1, wherein the opacity-altering composition is a dyed or fluorescent ink.
Claim 8
Dependent Claim
21 words
Support according to claim 1, wherein the synthetic substrate is a film or a sheet composed of at least one polyolefin.
Claim 9
Dependent Claim
12 words
Support according to claim 7, wherein the polyolefin is polyethylene or polypropylene.
Claim 10
Dependent Claim
27 words
Support according to claim 7, wherein the substrate consists essentially of high-density polyethylene, is formed by extrusion, is biaxially stretched and is optionally surface-treated with corona discharges.
Claim 11
Dependent Claim
35 words
Support according to claim 1, wherein the imprintable pigment composition comprises a mineral filler, at least one dispersant, at least one binder, optionally an insolubilizer, optionally an anti-static agent, and optionally a pH regulating agent.
Claim 12
Dependent Claim
62 words
A method of manufacturing a support according to claim 1, wherein at least one opacity-altering composition is deposited at specific sites on at least one of the faces of the synthetic substrate to form at least one authentication or security mark and wherein an imprintable, pigmented layer is deposited on the face with the mark and optionally also on the other side.
Claim 13
Dependent Claim
16 words
Method according to claim 11, characterized in that the opacity altering composition is deposited by photo-etching.
Claim 14
Dependent Claim
28 words
Method according to claim 11, wherein the imprintable pigmented layer has a dry specific weight between 5 and 30 g/m 2 and preferably about 10 g/m 2 .
