Description

200900263 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a card having a color changing film and a method of manufacturing the same. [Prior Art] "Cards with personalized information such as photos, signatures, fingerprints, personal text information, barcodes, or the like are used to prove identity for: "age" for security Area to verify driving privilege, for use in the following and for future use. To prevent counterfeiting of personalized material and subsequent use of forged cards, it is common to add security features that can better demonstrate tamper evidence for identification. An example of a security feature is a color-changing film. The color-changing film has hundreds of thin layers of biaxially stretched polymer' and exhibits a color when viewed directly and then converts to a different color when viewed from a large angle. The bond between the card and the card body is usually quite weak. Therefore, forgery can cut the card 'removing the film from the card body and reuse the film for counterfeiting the card: in addition, 'in the color film' Adhesion to the optical core: the hanging pole is low' so the interface between the surface layer and the optical core can easily occur: two sut «' even before the color film is laminated to the card as a primer The agent coats the color changing film to increase the bonding between the film and the card body, and the counterfeiting is to cut the card into the 'self-surface peeling optical core and reuse the optical core in the counterfeit card. [Invention] A card having a color changing film comprising a plurality of openings 126697.doc 200900263 and a method of manufacturing the same.

变色 " The color-changing film 4G suitable for the present invention includes any multi-layer optical # which exhibits _ color when viewed directly and then changes to another color when observed at a large angle. The preferred color changing film 40 is a clear to cyan color changing film (available from St. Paul, Inc.). The film 4 is substantially transparent when viewed directly, and becomes cyan when viewed at a large angle. The unmarkable custom indicia 44, such as the label, the name, the initials, or the like, is preferably embossed = on the color-changing film 40' where the indicia 44# is red gold when viewed directly and then viewed at a large angle Time is changed to. Color pattern 46 can also be used beneath film 4 to produce other color transitions when viewed through film 4〇. In addition, hidden security features 48 such as UV fluorescent inks, optical color changing inks, or the like can be added to provide additional security. The color film 4 of the present invention includes a plurality of openings 42. The openings may be any shape, such as a circle, a square, a triangle, a letter: a number, a centimeter slit, or the like, and may be any series, preferably in a conventional manner: a case: a column. The openings preferably comprise bi-directional slits, such as plus sign (7), parent and hatch (V), insertion mark (, Λ,), greater than mark (, > '), less than mark (|<|) or Similar symbols. Figure 3A depicts a type of bidirectional opening 42, 126697.doc 200900263 cross hatching. If a circular or bi-directional slit is also used to overlap or intersect with the other openings: the other opening I can be used to overlap the circular opening 42" of the line slit.

Γ Longitudinal or lateral arrangement from the edge of the card 10 to the other edge. The tie can be applied via a primer or adhesive to increase the bond between (4) and the thermoplastic surface 22 and the bond between the film 4 and the thermoplastic surface. When the film 40 is laminated under high temperature and pressure When the thermoplastic surface is between the crucible and the thermoplastic surface 32, the thermoplastic surfaces 22, 32 become soft and fused together via the opening 42 of the membrane 4. This mechanically locks the membrane to the thermoplastic surface 22 and top layer of the substrate layer. Between the first thermoplastic surfaces 32 of 30. If the mechanical locking system is sufficiently strong, at least one of the openings 42, 42, 42, 42 causes the film 40 to exhibit when the counterfeiter attempts to tamper with the film 40. Evidence of tampering 'This preferably prevents the film 40 from being reused. Evidence of tampering includes permanent stretching or damage to the film 40, such as tearing, cracking or delamination. Suitable lamination temperatures and pressures can be based on use as a thermoplastic The materials of the surfaces 22, 32 are selected. For example, to laminate two poly(vinyl chloride) surfaces, a temperature between about 140 ° C and about 15 (TC) and between about 300 psi can be used. Pressure from 2.07 MPa) to approximately 3 50 psi (approximately 2.41 MPa). The plastic surface 22 is capable of receiving an image 'then security image such as logo, microtext, guilloche, image or the like. The conventional ink can be utilized using conventional inks such as the following printing techniques commonly used for card printing 126697. Doc -10· 200900263 is printed on the surface 22: dye diffusion thermal transfer printing, dye sublimation printing 'laser printing' inkjet printing and laser engraving/marking/etching. It can also be used such as UV fluorescent ink, optical color change A hidden security feature 26 of ink or the like is printed on the surface 22. Additionally, a personalized material 12 can be printed on the surface 22, wherein a scrambling view such as a digital watermark, a coded image, or the like can be used. The text 14 is embedded with the data 12. A physical security element 28 such as a magnetic strip, a signature strip, a hologram, a 1C wafer (contact or non-contact) or the like can be added to the substrate layer 2 . If the thermoplastic surface 34 is capable of receiving an image, the personalized material 12 can be printed on the surface 34, wherein a scrambled text 14 such as a digital watermark, a coded image, or the like can be used. 12 is embedded together. To protect the thermoplastic surface 34 from wear, scratches, cuts or the like, a protective layer or other suitable mechanism may be added to the surface 34, such as an anti-wear coating of multiple discrete regions. In another aspect, the invention relates to a method of making a card comprising providing a substrate layer having a thermoplastic surface, providing a color changing film comprising a plurality of openings - providing a top layer having first and second thermoplastic surfaces 'and laminating the t color film between the thermoplastic surface of the substrate layer and the first thermoplastic surface of the top layer at elevated temperatures and pressures. If the thermoplastic surface 22 is capable of receiving an image, the method can include the security artwork 24 The hidden security feature 26 and/or the personalized material 12 is printed on the surface 22. Additionally, the method may include adding the physical security element 28 to the substrate layer 20. If the thermoplastic surface 34 is capable of receiving an image, the method can include printing the personalized material 12 onto the surface 34. If the personalized information is printed 126697.doc -11- 200900263 12 ' then the method may include embedding the scrambling text 14 with the material 12. Alternatively, the embossing of the color-changing film 4 can be performed by not printing the custom mark 44 and adding the hidden security feature 48 and using the color pattern 46 below the film 40.
