Definitions

  • This invention relates to validation of security papers, documents, banknotes, artworks and brand products.
  • Optical security elements that are able to change the polarization of incident light, may be used as such security features, such as holograms, liquid crystal optical elements, and polymer layers with hidden images visible in polarized light only.
  • a method of product authentication by forming a security label placed on the outer surface of protected product where a security label is comprised of a subsequently disposed transparent flexible substrate, a transparent thermoplastic lacquer layer, a metallized reflective layer and a transparent heat-sealable adhesive layer.
  • a relief-phase hologram with visible and hidden laser images is made in a transparent thermoplastic lacquer layer by hot embossing method. The visible image appears in white light, while hidden laser image becomes visible when the hologram is illuminated with coherent laser beam.
  • a polarized light-sensitive material is embedded into the security label; a polarizing encoding element is placed before the security label and then it is illuminated with blue-green light in order to record the hidden polarized image into the polarized light-sensitive layer; a polarizer is placed on the security label and illuminated with white light to reproduce the hidden polarized image; the polarized light-sensitive layer is situated on the outer surface of the transparent flexible substrate made of optically transparent material (see Patent # 2165360 of the Russian Federation, the invention description, Application # 95117875 of the Russian Federation, 1997.)
  • an ID card authentication system comprising an information carrier substrate, a partially light reflecting layer superposed over the said substrate, a phase quarter wave plate placed over the said reflecting layer.
  • a linear light polarizer is used for identification (see US Patent # 4659112, published on 21 April 1987 ).
  • the closest prior art reference to the claimed security label is a security label comprising: a sequentially disposed metallic reflective layer, a transparent substrate, a transparent thermoplastic lacquer layer and having an element that changes optical properties of the substrate to form a hidden polarized image.
  • the element is made on a face side of the substrate in the form of a relief image that locally changes the optical depth of the substrate (see UK Patent # 2318180 published on 17 February 1999 ).
  • a prior art reference to the claimed method of forming a security label is a method of producing a security label in which the security label is made of a sequentially disposed metallic reflective layer, a transparent substrate, a transparent thermoplastic lacquer layer and there is produced an element that changes optical properties of the substrate to form a hidden polarized image.
  • the element is made on a face side of the substrate in the form of a relief image that locally changes the optical depth of the substrate (see UK Patent # 2318180 published on 17 February 1999 ).
  • a prior art reference to the claimed authenticity verification method of products is a method for ensuring authenticity of products in which a security label formed by the method described above is placed on the outside surface of the certified object and a hidden polarized image is visualized by observing it through a circular polarizer. (see UK Patent # 2318180 published on 17 February 1999 ).
  • Document WO 2009/154506 discloses as security element having a reflective latent image on an optically anisotropic translucent substrate, printed on both sides.
  • the technical result of the invention is an implementation of a cost-effective and mass-producible security label with hidden polarized color images without any visible outlines of such polarized images.
  • the technical result of the invention includes method of forming a cost-effective and mass-producible security label with hidden polarized images without any visible outlines of such polarized images and method of the product authenticity verification with the assistance of such security label.
  • the claimed technical results of the claimed security label comprising: a sequentially disposed metallic reflective layer and an optically anisotropic transparent substrate, has been achieved at the expense of that the element changing the optical properties of the substrate is made in the form of mask that covers a face side of the substrate by the same metallic material that is used for the reflective layer, and the mask is performed using a solid fill printing method with blank spaces made in accordance with the hidden image graphics.
  • the total optical thickness L d ( n e - n o ), where
  • the mask should be performed using a solid fill printing with blank spaces made in accordance with the hidden image graphics.
  • the second technical result is achieved by forming at least one more sequentially disposed additional optically anisotropic substrate with an element changing the optical properties of the substrate and made in the form of the mentioned mask.
  • the metallic reflective layer on a reverse side of the film may be formed by solid fill printing with a metallic ink without any blanks.
  • the security label should be applied to the outer surface of the protected product using an extra adhesive layer.
  • the mask on a face side of the substrate may be covered by at least one masking layer made preferentially of the same metallic material as the reflective layer and the mask; the density and/or thickness of the said layer should be enough to hide the mask outline without impeding the light transmission through the masking layer.
  • the security label may be formed directly during the printing process as a part of protected products like packing, labels, scotch tape, sealing tape based on optically anisotropic transparent film.
  • the optically anisotropic transparent substrate may be an oriented polymer film selected from the group that includes polyethilentereftalate, biaxially-oriented and axially oriented polypropylene film, or oriented lacquer layer made from the polymer group that includes polyvinyl alcohol (PVA), polystyrene, polycarbonate and ethylcellulose.
  • PVA polyvinyl alcohol
  • the claimed security label is based upon the optically anisotropic substrate made of the film (1) (see Fig. 4 ) with a reverse side covered with the metallic reflective layer (2).
  • a reverse side of only one (lower) film 1 is covered with the metallic reflective layer (2).
  • a heat sealable adhesive layer (not shown on the drawings) may be applied on the metallic reflective layer (2). Such adhesive may be used to stick together the layers of the film (1) shown in Fig. 5 .
  • the claimed method of producing a security label can be realized as follows (see Figs. 1 to 4 ).
  • An optically anisotropic transparent film (1) is used for printing.
  • the film thickness is of no importance.
  • One of the following printing methods is used to form a hidden polarized image: offset printing; letterpress printing; flexographic printing; intaglio printing, etc.; the same metallic ink is used during all printing stages.
  • the finished security label is obtained (see Fig. 4 ) without any outlines or relief visible on the surface.
  • Stage 2 When a multilayer substrate is required, a relevant number of substrate layers is made during Stage 2 (without any reflective layer). The prepared additional substrates are laid on the substrate implemented during Stages 1 and 2 and sticked together by optically transparent adhesive. Operations specified for Stages 3 and 4 are performed as described above.
  • the security label can be made (printed) directly on the protected product.
  • the metallic reflective layer (2) may be covered by a heat-sealable adhesive (not shown on the drawings) to stick the security label onto a surface of the protected product.
  • the claimed method of producing a security label is intended to form the hidden images that become visible in polarized light. It can be used with any printing methods: offset printing; letterpress printing; flexographic printing; intaglio printing, etc.
  • the claimed first version of a security label ( Fig. 4 ) is used for the product authenticity verification as follows (see Figs. 9 to 10 ).
  • the security label is placed on the outer surface of the protected product or is embedded into the same. If the claimed security label is illuminated with white light no images or relief are visible on its surface.
  • the light passing through a polarizer (6) to the security label becomes polarized.
  • the polarized light passes through the layers (5) and (4) and the sections of the mask (3) that are not covered with metallic ink, then goes into the transparent substrate (1) and is reflected from the reflective layer (2).
  • the mask (3) acts as an element changing the optical properties of the substrate (1) in the sense that the sections of the mask (3) that reflect the polarized light without altering the same transfer this property to the substrate (1) because under these sections of the mask there appears no light in the substrate. Light beams reflected by the layer (2) re-pass through the substrate (1).
  • the polarization of light is altered, however, the human eye does not detect any changes in the polarized light reflected by the mask and passed through the optically anisotropic substrate, and therefore the image remains invisible with the naked eye.
  • the hidden polarized image generated by changes in polarization of light becomes visible if observed through a circular polarizer (6), because the polarized light, reflected by the mask without any changes in polarization, is absorbed by a circular polarizer (6), while the light, that has passed through the optically anisotropic substrate and changed its polarization state, passes through a circular polarizer (6) without any changes.
  • a polarizer (6) can be put on the security label or, alternatively, the system comprising of polarized glasses and a source of polarized light can be used.
  • the claimed security label enables the visualization of a white image (7) on a dark-blue background that coincides with the image shown in the mask (3).
  • the same way can be used for authentication with assistance of the second and the third versions of the security label, however, in this case, the hidden image is colored.
  • Colored image is generated in such security labels due to chromatic polarization (coloration of initially white light) of the light that has passed through linear/circular polarizer (6) and optically anisotropic film (1) with reflective layer (2) (see Figs. 6 and 7 ), the optical axis of this film is perpendicular to the light traveling direction.
  • a polarizer lets light pass through if the electric field oscillations E 0 , are directed along the polarizer axis. Passing through the optically anisotropic film a light wave splits into two waves with mutually orthogonal electric field oscillations E x and E y . Both waves (ordinary and extraordinary) propagate in the optically anisotropic film with different velocities; therefore the phase difference ⁇ is generated between them.
  • the fields in both waves are directed along to the polarizer axis, A lin - for the linear polarizer and A cir - for the circular polarizer. Due to the phase quarter wave plate used in a circular polarizer, the effective circular polarizer axis A cir at the polarizer output is orthogonal to II polarizer axis at the input.
  • T cir sin 2 ⁇ 2 ⁇ ⁇ ⁇ sin 2 ⁇ ⁇ / 2
  • Table 1 shows interferential colors for different values of optical thickness of the optically anisotropic film (or total optical thickness of a pack of optically anisotropic films) with the reflective layer.
  • Table 1 shows interferential colors for different values of optical thickness of the optically anisotropic film (or total optical thickness of a pack of optically anisotropic films) with the reflective layer.
  • Table 1 shows interferential colors for different values of optical thickness of the optically anisotropic film (or total optical thickness of a pack of optically anisotropic films) with the reflective layer.
  • Table 1 shows interferential colors for different values of optical thickness of the optically anisotropic film (or total optical thickness of a pack of optically anisotropic films) with the reflective layer.
  • Table 1 shows interferential colors for different values of optical thickness of the optically anisotropic film (or total optical thickness of a pack of optically anisotropic films) with the reflective layer.
  • Table 1 shows interferential colors for different values of optical thickness of the optically anis
  • the claimed versions of the security labels with hidden polarized images may be realized by proper selection of the optical thickness of the substrate or substrates (for multicolored hidden images), by forming a reflective layer, a mask or masks (for multicolored hidden images) with the same metallic material as for the reflective layer, and a masking dispersing layer used to hide the outlines of the polarized image on the label. Verification of the security label with hidden polarized images is made using a polarizer.
