Description of the invention: [Technical field to which the invention pertains] The present disclosure relates to a laser marker label. More specifically, the present disclosure relates to a laser marker label that, once bonded to an article to be bonded, prevents or prevents peeling from the article for counterfeiting, reuse, and other purposes. This disclosure is also directed to an article equipped with such a laser tag. [Prior Art] Laser tags and other tags have been used for labels such as automotive components. Recently, it has occurred that the removal of the label from the automotive component is used for counterfeiting and again = label bonding to other automotive components. Prior art labels have the disadvantage that the bond strength of the article to be bonded is relatively low compared to the strength (resistance to cracking) of the label substrate. Therefore, when a sharp blade (such as a razor) is carefully inserted between the article to be bonded and the label, the label can be peeled off from the bonded article without the label substrate breaking. To this end, there is a strong need to prevent the re-use and counterfeiting of labels. Various precautions have been proposed in the past to prevent stripping, re-use and counterfeiting of laser-marked labels and other labels. For example, Japanese Unexamined Patent Publication No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. No. One of the printed portions having characters and the like, and one of the label bonding sides sequentially bonded to the substrate contains an adhesive layer of a fluorescent dye and a release sheet. An unexamined patent publication No. 9-277423 describes a security element 125346.doc 200828199: or a sheet comprising a transparent substrate that cuts at least ultraviolet rays and an adhesive layer containing a colored w.

Japanese Unexamined Patent Publication No. 2002-40946 describes a label for preventing re-bonding/illegal use, comprising a label substrate formed of a transparent film, and a pattern formed under the label substrate to contain characters and/or graphics. The release layer, a printed layer formed by being able to be seen through the label substrate and/or the release layer, and an adhesive layer formed under the printed layer. In addition, Japanese Unexamined Patent Publication No. 2003-316271 describes an anti-counterfeit adhesive wearing a 'substrate including a base (A), a part laminated on a label base (A) and having easy peelability. a peeling layer (b), an ink layer (C) laminated on the special layer and formed of ink, and a re-peelable follow-up adhesive layer (D) laminated on the ink layer (C), which can be peeled off again The following adhesive layer (D) has re-peelability from the bonded article and can be peeled off at the interface with the bonded article to follow the label substrate (A), wherein the re-peelable follow-up adhesive layer (D) comprises An adhesive layer (Da), 125346.doc 200828199 a urethane type adhesive layer (Db) and a re-peelable adhesive layer (D. c) ° 未 unexamined patent publication (case) 2003- No. 345255 describes an anti-counterfeiting label which is formed by printing a peeling layer having releasability on the back surface of a transparent film, forming a printing layer covering the back surface of the transparent film and the peeling layer, and printing. Forming a buffer on the layer Quality and releasability of the buffer layer may be; and an adhesive layer formed on the buffer layer. Japanese Unexamined Patent Publication No. 2004-125927 describes a layered label having an upper layer label and a lower layer label, wherein a protruding block is formed on the upper label and an end line extending along the upper layer. It is printed on the lower label and the slit is formed at a suitable position on the upper label. However, even when a slit or other security mark is incorporated into the above label, the label substrate can be peeled off from the adhered article by using a sharp blade, although the time required and the difficulty of operation become higher. When the slit is formed in the label, printing defects may occur at the time of printing the label surface, and it may happen that the time during which the label is peeled off from the lining and bonded to the bonded article occurs due to the presence of the slit as the triggering device. The label is broken. In the case of the security label according to the prior art, the label has a multi-layer film form of a complicated structure, so that not only its manufacturing is difficult, but also such labels cannot be easily applied to laser marking labels which have received attention in recent years. SUMMARY OF THE INVENTION In some embodiments, the present disclosure provides an anti-counterfeit label that eliminates the problems of prior art anti-counterfeit labels and that strips the label from the bonded article by bonding the target to the article. Even when doing deliberate operation) 125346.doc 200828199 can not be used again. In some embodiments, the present disclosure provides an anti-counterfeit label that does not have to incorporate a security indicia, such as a slit that prevents reuse and counterfeiting that can result in label damage. In some embodiments, the label has a simple construction and is further suitable for laser marking labels. In some embodiments, the present disclosure provides an anti-counterfeit label that can be improved in design and graphics by thin laser cutting using laser marking and laser. In some embodiments, the present disclosure provides an anti-counterfeit label that is excellent in weather resistance and curve following properties in addition to improved design and graphic features and that does not create cracks when applied to the curved portion of the bonded article. And enemy lines. Further, in some embodiments, the present disclosure provides an article having the above-described anti-counterfeit label. These and other features will be readily apparent from the following detailed description. [Embodiment] According to an intensive study for realizing the above-described features, the inventors have found that an anti-counterfeit standard iron is constructed in such a manner as to have at least two layers of the label layer: the label substrate is effective. Specifically, the base of the security layer comprises a main layer having a brittleness and a sub-layer having a higher toughness than the main layer. The eight disclosures provide a laser marking label having a label layer on the adhesive layer that is capable of accepting a laser writing pattern, wherein the label layer includes at least the top-down order as the sub-layer - a label layer and a second label layer of the main layer. The first label layer (sublayer) is selected in the laser writing area of the 125346.doc 200828199 laser writing area during laser writing, and is selected and moved. In addition, and due to the removal of the first label layer, the second label layer + paper layer (main layer) is exposed to the laser writing region. The second label layer has a greater brittleness than the first label layer. / The disclosure also provides an article having an anti-counterfeit label on one surface thereof, wherein the anti-counterfeiting label is by laser writing on the laser marking target according to the present invention and then by 僚耆, A label obtained by bonding a laser marking label to the surface of the article by the adhesive layer. In some embodiments, as will be understood from the detailed description below, a label substrate is constructed by combining a specific first label layer, a first one, and a first layer.

The other side is because the anti-counterfeit label contains low brittleness (Example #, non-brittle layer, so the label substrate does not break when the anti-extrusion twist is adhered to the bonded object, thereby satisfying two Requirements - "The security label according to this disclosure does not have to be incorporated into a security function such as a slit. Therefore, the security label does not appear to be caused by the existence of such a slit: and because the security label is simple Construction, so it will not be damaged during manufacturing, and during transportation. It is important that the label can be used as a Thunder, i P, and C. In recent years, the demand for laser marking labels has increased because f. The fine and high quality mark cannot be achieved by other executable printing. 125346.doc 200828199 In the anti-counterfeit label of the root 2, the improved design and graphic features can be improved. In combination with thin die cutting and laser marking while achieving reduced system construction dimensions, in some embodiments, in addition to improved design and graphic features, security labels provide excellent weatherability and curve following properties. In fact, in some embodiments 4, even if the anti-counterfeit label is bonded to the curved portion of the bonded article or the portion of the other complicated shape, cracks and wrinkles do not occur. Further, in some embodiments, The present disclosure provides an article equipped with an iron standard having a majority of the features of the above-described security label. The security label may be particularly advantageous for automotive components. The present disclosure provides a laser marking label having a capable The label layer of the write pattern is produced by laser (ie, a label that can be marked with a laser). In some embodiments, the target is laminated on a peelable backing layer via a layer. The article also provides an article having a laser marking label bonded to a predetermined portion after applying the laser marking to the label. Here, the term "pattern," means Various types of patterns, which may be written by laser marks and include lines, characters, numbers, symbols, marks, logos, barcodes, lines, patterns, and the like, and combinations thereof, although such patterns are not particularly limited. The laser marking label can generally have the layer configuration shown in Fig. 1. In other words, in the laser marking label 10, the label layer 5 is laminated to the peelable backing layer 4 via the adhesive layer 3. The label layer 5 The top and bottom include a first label layer 1 as a secondary layer and a second label layer 2 as a primary layer. Incidentally, the laser marker label 10 shown in the drawing represents an example and may optionally have 125346. Doc -11- 200828199 One or more additional layers. 2 In this laser marking label, the first label layer is written by laser as indicated by the hoe L1 as shown in Fig. 2. The pattern is selectively removed. In other words, when a laser having a predetermined intensity is used to scan the first label layer 1 and writing is performed, the first label layer i is burned only in the laser writing region (hereinafter also referred to as "etching ") and selectively remove. Since the removal step is selected here only the first ticket layer W is removed from its entire thickness, the second label layer 2 as a basis is thus exposed but not surnamed. Therefore, when the laser mark label 1〇 is inspected with the eye after the laser writing, the first label layer 1 and the second label layer 2 partially exposed by the predetermined pattern can be observed, and the written private number 5 The pattern can be identified by the difference in contrast between the first label layer 丨 and the second label layer 2. By changing the configuration of the first label layer 丄 and the first private layer 2 as necessary, the marking pattern can also be identified by utilizing differences in characters other than contrast. The difference in contrast for identifying the mark pattern can be confirmed by various means, but a method is proposed in which the first label layer 第二 and the second label layer 2 are colored differently from each other' and the first label layer 1 is selected After the sexual removal, the color difference between the first label layer i and the second label layer 2 is used to recognize the mark pattern. The color difference of the label layer is not particularly limited as long as the excellent contrast can be obtained to obtain an excellent marking effect. Therefore, the first label layer and the second label layer can be colored to any color. For example, when the first label layer 1 is colored black and the second layer 2 is colored white, the white label s pattern appears on a black basis and the recognition effect becomes apparent. In the laser marking label 10, the first label layer 1 and the second label layer 2 are executed by 125346.doc -12-200828199 -Z in a manner of 'but generally and advantageously, they can be performed by using 厗m - Hey. The colorant can be advantageously used in the form of blending the colorant in the desired amount with the material used to form the first label, the second label layer 2. Eight;: Bucket and dye can be used as a coloring agent singly or in combination. For the purpose of uniformity and dyes, the use of pigments and dyes in the form of powders or fine particles = examples of pigments and dyes suitable for use in the practice of the invention include carbon; upper teeth black, titanium oxide, oxidized words, test carbonic acid And titanium (four), although ... black pigment for the heart color: two, the laser is heated and easily burned out. Because the second = easy to be written with the first label layer! . When a person is required, it can be advantageously used as a coloring agent as a coloring agent. Using a combination such as an emulsified titanium package to achieve a specific identification of the I-pattern of the laser marking 10, Ming powder, mica powder, pearl mica may be used in combination as an example, and may be used as a coloring aid. When the hue of the hue or the like is imparted to the mark pattern such as a metallic hue, the pearl mica is in the laser mark label 10, the first-identification brittleness and the first-label layer! The brittleness is characterized by a label layer! Great brittleness. When the iron layer 2 passes through the adhesive layer, the bonded material has a ratio to the bonded article. The laser marker label 10 has a relatively strong bond strength. When attempting to use the second label layer 2 thus formed to be brittle by the adhesion between the driver layers 3, the label is removed from the label 10, so that it is attempted to become conspicuous, and the label J 0 : is bad. Therefore, the stripping of the non-lunar is again used for counterfeiting, etc., because the peeled off 125346.doc -13- 200828199 is damaged. In the laser marker label 10, the brittleness of the first signature layer 1 and the second standard layer 2 can be expressed by the breaking point load and the elongation after break. When the break may be small and the load at this time, the load of Fenshi 1 is appropriate, the value represents the suitable brittle load and the elongation after break are both V ^ ^ by JIS B7721 (stretch / compression tester): kg : Measurement of the load point measurement method of the fracture point of 疋. The load at the break point of the laser marking label 1 〇 '2 of the second label layer 2 is usually about 30 N/25 mm or less, and preferably about 10 Ν / 25 _ to about 3 〇Ν / 25 _. The collector layer (4) (iv) has a long rate t of about 5% or less, and preferably 3% or less. The armor layer 1 preferably has an elongation at break of 15% or more to support the label layer 2 prior to bonding. - in the example, it is preferable to add only - the brittleness-imparting agent to the second label layer 2 in order to generate an inert property between the first label layer i and the second label layer 2 - the brittleness imparting agent is given to the second The iron layer is physically and mechanically sturdy, and due to this brittleness, it provides an anti-stripping function to the resulting label. The brittle agent can be an organic material or an inorganic material as long as such functions are available. In general, an inorganic material can be advantageously used as a brittle imparting agent in consideration of compatibility with other components of the standard layer. It is suitable as an organic material for brittleness-imparting agents: including talc, sulphur dioxide, sulphuric acid, sulphuric acid and oxidized chin. Further, the brittle imparting agent may be formed of a material such as stainless steel, recorded, or genus. These fragility imparting agents may be used singly or in combination of two or more. Among these materials, talc is preferably used, and preferably, the powder imparting agent can be used in various forms, but it is usually used in the form of 125346.doc -14-200828199 or fine particles. The size (diameter) of the brittle imparting agent can vary over a wide range, but it is usually in the range of about i μm to about 3 μm. The brittleness imparting agent can be advantageously used in the form of blending a necessary amount of the brittle imparting agent into the raw material for forming the second label layer in the same manner as the above-described colorant. Subsequently, the construction of the laser tag label and its use according to the present invention will be explained in more detail. In the laser marking label according to the present invention, the first label layer may be formed of a resin material generally called a binder (for example, an acrylic resin, a urethane resin or a mixture thereof as a main component). . In some embodiments, an acrylic resin is preferred as the main component of the first label layer. For example, an acrylic polyol resin can be advantageously used. The 'thick layer' is colored to a different color than the second label layer to produce a contrast between the first label layer and the second label layer. The coloring of the first label layer is usually carried out by using the above coloring agent. The blending amount of the coloring agent can be made in the - wide & library & In the case of black, the blending amount is usually in the range of from about 1% by weight to about 1% by weight based on the total amount of the raw materials of the label layer. The formation of the first label layer can be performed by any thin film formation method. A general film forming method such as a doctor blade method, a calender roll method (-(10) method), a τ-type mold method, a blow molding method, an inflation molding method, or the like can be employed. For example, film formation can be carried out by applying a solution of the first label layer forming material to the support subjected to the release treatment. The coating solution can be prepared using ethyl sulfonium methyl ethyl ketone, terpene benzene, methanol, ethanol, and isopropyl alcohol. The second label layer and the adhesive layer are sequentially laminated on the label layer of the obtained 125346.doc 200828199. According to another method, At m + may also form a layer of the label layer, the second label layer and the layer simultaneously. Layer. Depending on the details of the label and its application, the first standard layer can have a variety of thicknesses. The thickness of the first label layer is typically in the range of from about 5 (four) to about 15 Å. When the thickness of the first label layer exceeds 15 Å, the appearance characteristics, the printing characteristics, and the brittle characteristics thereof applied to the resulting label are adversely affected. The first label layer and (2) 〇 (1) can burn out (etch) the first label layer with a predetermined laser beam write intensity when the other requirements are defined by the following requirements. However, only the second label layer is exposed, and even when etching the second label layer, the money should only remain at a negligible level. (2) During the normal label bonding operation, the first label layer can be stably stabilized by the adhesive layer and the second label layer is broken. The second label layer may be formed of a resin material generally referred to as "adhesive" in the same manner as the first label layer. For example, an acrylic resin, an amino formic acid resin or a mixture thereof may be used as a main component. In some embodiments, the acrylic resin is preferred as the main component of the second label layer. For example, an acrylic polyol resin may be advantageously used. The second label layer is colored differently. The color of the first label layer is used to create a contrast between the first label layer and the second label layer. The coloring of the second label layer is typically performed by using the coloring d described above. The amount of colorant blending can vary over a wide range. In the case of white, the blending amount is usually in the range of from about 2% by weight to about 6% by weight based on the total mass of the raw material of the label layer. 125346.doc •16- 200828199 Second label layer step-by-step The above-mentioned shirting agent can use various machine materials and inorganic (4) as the lyotrope-imparting agent, and the boring stone is especially suitable in the boring material. Although the amount of talc blended with other brittleness can be varied within a wide range. , It is usually in the range of from about 20% by weight to about 75% by weight, based on the total amount of the raw materials of the iron-plating layer, preferably in the range of from about 20% by weight to about (%) by weight. The blending amount of the brittle imparting agent When the amount is less than 2% by weight, the obtained second standard layer is not brittle and the peeling prevention function cannot be obtained in the label layer. For example, the laser mark label can be self-bonded by inserting the bayonet into the adhesive layer. The article is smoothly peeled (four) and cracked. On the contrary, when the blending amount of the brittle layer exceeds 75% by weight, the second label layer becomes brittle and the label is peeled off or the label is removed from the inner layer. When the adhesive is bonded to the bonded article, the label substrate will be broken. The formation of the (4) two-label layer can be carried out by any film forming method. Preferably, a general film forming method such as a doctor blade coating method or a calender roll method can be employed. , Τ type molding, blow molding, inflation molding, etc. For example, film formation can be carried out by applying a solution of the second label layer forming raw material to the support member subjected to the peeling. Ethyl acetate, methyl ethyl toluene, The coating solution was prepared by alcohol, ethanol and isopropanol. The resulting second label layer was laminated to the first label layer that had been formed or was formed. The adhesive layer was then laminated to the second label layer. According to another method, it is also possible to simultaneously form and laminate the first label layer, the second label layer and the adhesive layer. The second label layer can have various thicknesses depending on the details of the label and its application. The thickness of the second label layer Usually in the range of about 40 μη1 to about 120 μη1 125346.doc -17- 200828199. When the thickness of the second label layer is less than 40, the rigidity disappears, the processing factor is adversely affected, and the laser penetrates during printing. The possibility of a two-label layer appears. Conversely, when the thickness exceeds 12 squeaks, the label becomes thicker so that the brittleness decreases and the curve following property deteriorates. When defined from the other-state, the second label layer satisfies the following requirements (1) And (2) 〇 (1) can - the dragon beam writes the human strength (four)] the second label layer to the middle of one of its label layers.

(3) Labels should not be damaged by a common label bonding work. The first label layer and the second label layer may further contain an additive other than the colorant. Examples of the additives which can be used arbitrarily include an antioxidant, a collector, a light stabilizer, an antistatic agent, a flame retardant, a dispersant and the like. The blending amount of such additives is not particularly limited. The laser marking label further includes an adhesive layer for bonding the label layer to the bonded article. The adhesive layer can be formed by using a heat-sensitive adhesive or a pressure-sensitive adhesive which is generally used in the field of labeling. Examples of suitable adhesives include acrylic adhesives, olefin-type adhesives, epoxy-based adhesives, and urethane-based adhesives' although they are not particularly limited. The acrylic type adhesive can be particularly advantageously used in consideration of the fact that the bonded u is suitable for the bonding strength. The adhesive layer can be used in various bonding strengths and various thicknesses. The bond strength of the adhesive layer to the bonded article is preferably at least about 2 〇 N / 25 faces. Adhesive layer 125346.doc -18- 200828199 Can be used in various thicknesses. The thickness of the adhesive layer is usually in the range of from about 10 μηι to about 40 and preferably in the range of from about 1 〇 to about 3 Å. When the thickness of the adhesive layer is less than 10 _, the bond strength may decrease, and conversely, when the thickness is 40 μm or more, there is a possibility that a sharp edge such as a razor can be inserted (aggregated fracture) without destroying the second label layer. The incidental adhesive layer also bears the responsibility of the stable U-brittle second label layer together with the first label layer. In the case of the second embodiment, the laser marker label further contains a backing layer for protecting the adhesive layer, which can be easily peeled off before use. The backing layer can be a layer of sheets, sheets and films which are commonly used in the field of labels and which, for example, are subjected to a release treatment by a release agent such as a silicone resin. With the V-place 'When the thin-die cut is applied to the laser marking label, the inner layer must be formed of a material that does not burn its lower surface under the laser thin-die cutting strength or must have an enough to prevent burnout. thickness. When a release treated paper is used as the backing layer, it is preferred to use a release treated paper having a thickness of at least about 1 Å. The laser marking or thin die cutting process may have been applied to the first label layer of the laser marking label in accordance with the present invention by the method described in detail below. Alternatively, the laser marking label can be designed such that such processing is not applied and the processing is applied first prior to use. In either configuration, the laser marker 2 preferably has a large size that provides a large number of discrete labels. The laser marker = label typically and preferably has the form of a rectangular sheet or a form similar to a rectangular sheet. The laser tag label suitably forms an elongated product and is rolled into a roll. Laser tagged label rolls are easy to store, transport and handle. 125346.doc _ 19- 200828199 Laser marking labels can be bonded to and used in a variety of bonded items depending on their construction and characteristics. In particular, laser marking labels can be drawn not only by laser markings - small and high quality patterns, but also with high weatherability and curve following properties, and when bonding laser marking labels to bonded objects with complex shapes At the time, it can be easily bonded without causing defects such as cracks and wrinkles. Therefore, the laser marker tag can be advantageously used for, for example, an automobile component and a locomotive component. When using a laser tag, a pattern is first written to the first tag layer by using a laser. Depending on the construction of the tag and its application, the pattern to be written can be versatile and a desired pattern can be obtained by any combination of characters, numbers, logos and lines. When determining the pattern, it is recommended to consider the color of the first label layer and the second label layer and provide a marking pattern with excellent appearance, contrast and recognition rate. Laser writing (i.e., laser marking) can be performed in a conventional manner. A c〇2 laser (wavelength = 10·6 μηι) and a YAG laser (wavelength = 1〇64 μ岣) can be used as the mark laser. The resulting pattern can be reduced by contracting or amplifying the beams of these lasers. Or become larger. The intensity of the laser can vary over a wide range when marking, but it is usually in the range of about 10 W to about 1 〇〇 w. In addition to the laser marking, it will be used by using a laser. The cutting process (i.e., thin die cutting) is advantageously applied to laser tag labels other than laser markings. In other words, by using a laser writing having a ratio greater than that used for the first label layer The laser beam L2 of the intensity of the laser beam L1 完全 can completely remove the first label layer 丨, the second label layer 2 and the adhesive layer 3 in a predetermined pattern (thin die cutting line) without leaving glue. The discrete laser marking label 1〇 can be used separately from the lining layer 4 when using its 125346.doc •20-200828199. When performing thin mode (4) by laser, 'C can be used in the same way as marking lasers. 2 Laser and YAG lasers are used as lasers for thin-die cutting. Both marking and thin-die cutting can be used by using the same The laser system is implemented, so the system is suitable for the processing factor, space and cost. However, in the case of thin die cutting, it is necessary to remove the first standard layer and the second standard layer simultaneously. Adhesive layer, and for this reason, it is necessary to use a laser having a higher intensity than the marked laser. The laser intensity can be varied over a wide range when performing thin die cutting, and it is usually in the range of about loo w to about 200 w. After the marking by the laser and the thin die cutting, the label substrate of the laser marking label is peeled off from the backing layer, and the label is bonded to the bonded article via the exposed adhesive layer. When necessary ^ a fixture to prevent air retention. The laser marking label can be firmly bonded to the sticky, 'D object rm, and because the second label layer is so fragile, so when someone is for illegal purposes* When attempting to peel the label, the second label, which is the brittle layer, is destroyed. In other words, the label cannot be held while maintaining its original shape and appearance. This function may prevent the label from being peeled off and reused. 'The second label layer as the brittle layer is sandwiched between the upper first label layer and the lower adhesive layer and is stably held. Therefore, the label is not destroyed during ordinary bonding work. In another aspect, the present disclosure Also provided is an article having the above-described laser marking label on its surface. In the case of this article, a laser marking label is used after laser writing and peeling of the backing layer, and the laser marking label is adhered. The layer is bonded to a predetermined position of the article. 125346.doc -21- 200828199 Generally, there is no specific limitation on the kind of the article equipped with the label. The article is preferably a carrier component such as an automobile component and a locomotive component, and the label is often found therein. Illegal use and forgery.
