The marking is provided on a wrapper, such as a plug wrap, a smokable material wrap, or a tipping paper wrap. The marking may include aligned embossed and printed features with a portion being misaligned. The marking may include a colored adjacent or surrounding region into which the indicia may be hidden and from which it may appear, depending on the viewing angle. The marking may allow a consumer to identify the smoking article as genuine, as opposed to counterfeit.SELECTED DRAWING: Figure 5A

Description

  The present disclosure relates to smoking articles and wrappers for smoking articles having invisible signs.

  Combustible smoking articles such as cigarettes typically have a finely cut tobacco surrounded by a paper wrapper that forms a tobacco rod. Cigarettes are used by smokers by igniting one end of the cigarette and burning a chopped tobacco rod. The smoker then accepts mainstream smoke into his mouth by drawing it out at the opposite or mouth end of the cigarette, which usually contains a filter. Depending on the cigarette brand, the finely cut tobacco can be one type of tobacco or a mixture of two or more types of tobacco.

  Other known smoking articles include, for example, smoking articles where the aerosol is generated by electrical heating or by transferring heat from a combustible fuel element or heat source to an aerosol generating substrate. During smoking, volatile compounds are released from the aerosol-generating substrate by heat transfer from a heat source and are entrained in the air drawn through the smoking article. As the released compound cools, it condenses to form an aerosol that is inhaled by the consumer. Also known are smoking articles where nicotine-containing aerosols are produced from tobacco materials, tobacco extracts, or other nicotine sources without burning and in some cases without heating, for example by chemical reactions. is there.

  Various parts of the smoking article may include a wrapper or housing that is visible to the consumer. For example, cigarette filter rods are usually wrapped with plug wrap paper, cigarette rods are usually wrapped with cigarette paper, and tobacco rods and filter rods are usually attached with chipping paper. A non-flammable smoking article may have a similar wrapper or housing for including components of the smoking article. Plug wraps, cigarette paper, chipping paper, other wrappers or housing parts of smoking articles may be visible to the consumer.

  The housing or wrapper is usually plain white or colored. Sometimes indicia, such as images, logos or text, are printed on one or more of these wrappers so that the user can easily recognize and identify the product. At least one published patent application WO 2011/042354 describes a wrapper with an aligned printed pattern and an embossed V-shaped feature, on one side of that feature. One color is provided, and the other side is provided with a different color so that the different colors predominate when viewed from different angles.

  While signs such as images, logos, text, or color shifting can be used to identify authentic products, the number of counterfeit smoking articles continues to increase. Therefore, a more sophisticated mechanism for identifying a product as authentic is desirable to prevent counterfeiting.

  One object of the present disclosure is to depict a smoking article or wrapper thereof that has indicia that is more difficult to counterfeit than the indicia previously depicted. The indicia may allow the user to more easily identify that the smoking article is authentic. In embodiments, indicia are visible only from a single specific angle or from several specific angles, but are not visible when viewed from other angles.

  Another object of the present disclosure is to depict a smoking article or wrapper thereof having an invisible mark that becomes visible when viewed from a particular angle. Such smoking articles and wrappers can be more easily accepted by the user as a sign of authentication.

  In a first aspect, the smoking article or the wrapper or housing for the smoking article is seen with at least one other angle, hidden with or in the adjacent part when viewed from at least one angle. Sometimes includes indicia that become visible to adjacent areas. For example, in an embodiment, a smoking article or a wrapper or housing for a smoking article includes a marking that includes a patterned portion and an adjacent portion. The patterned portion includes a printed pattern and an embossed pattern aligned with the printed pattern. The printed pattern includes a first color and an adjacent second color. The first color of the printed pattern is provided on one side of the embossed feature visible from the first angle, and the second color of the printed pattern is embossed visible from the second angle. Is provided on the second side of the feature. The first color and the adjacent second color are mixed to produce a third color when viewed from a third angle. Adjacent portions of the marking are provided with any one of the first, second or third colors. Thus, when aligned and embossed features and colored features are visible from a single particular angle, they are not easily distinguished from adjacent portions. For example, if the adjacent part is a third color, the aligned embossed and colored features will be in or together with the adjacent part when viewed from a third angle. Hidden and invisible. However, when viewed from the first or second angle, the aligned embossed and colored features are distinguishable from adjacent portions and do not become hidden.

  In a second aspect, the smoking article or wrapper or housing for the smoking article includes indicia that becomes visible when viewed from a selected range of angles. For example, in an embodiment, a smoking article or a wrapper or housing for a smoking article includes a marking that includes a printed pattern and an embossed pattern aligned with the printed pattern. The printed pattern includes a first color and an adjacent second color. In the first part, the first color is printed on the first side of the embossed feature visible from the first angle, and the second color is embossed visible from the second angle. The embossed pattern is registered with the printed pattern so that it is printed on the second side of the feature. In the second part, the embossed pattern is offset with respect to the printed pattern so that the second color is printed on one side of the embossed feature visible from the first angle. The adjacent first and second colors mix when viewed from a third angle to produce a third color. Thus, in some embodiments, the indicia can be seen when viewed from a first angle, but not when viewed from a second or third angle.

  In a third aspect, a smoking article or a wrapper or housing for a smoking article includes an invisible mark when viewed from a selected range of angles. For example, in an embodiment, a smoking article or a wrapper or housing for a smoking article includes a marking that includes a printed pattern and an embossed pattern aligned with the printed pattern. The printed pattern includes a first portion and a second portion. The first portion of the printed pattern includes a first color and an adjacent second color. The second portion of the printed pattern includes a first color and an adjacent third color. In the first part, the first color is printed on the first side of the embossed feature visible from the first angle, and the second color is embossed visible from the second angle. The embossed pattern is registered with the printed pattern so that it is printed on the second side of the feature. In the second part, the first color was printed on one side of the embossed feature visible from the first angle, and the third color was embossed visible from the second angle The embossed pattern is registered with the printed pattern so that it is printed on the second side of the feature. Thus, in some embodiments, the indicia may not be visible when viewed from a first angle, but may be visible when viewed from a second or third angle.

  In embodiments of the various aspects described above, the printed pattern is aligned with the embossed pattern so that the indicia are visible when viewed from one or more angles. When the printed pattern and the embossed pattern are in register with each other at the marking, the first color is dominant when viewed from the first angle, and the second color is dominant when viewed from the second angle It is. If the printed and embossed patterns are offset, the third color, when viewed from the first angle, the second color is dominant or is a mixture of the first and second colors Is dominant. Despite the fact that one or more portions of the printed pattern and the embossed pattern are offset, the overall printed pattern and the embossed pattern are considered to be aligned to the extent that the desired appearance and disappearance of the indicia is achieved. It is understood.

  One or more embodiments of a smoking article or wrapper described herein may provide one or more advantages over smoking articles or wrappers for smoking articles previously manufactured or depicted. For example, the high complexity of the pattern and its confusion or invisibility can result in a smoking article or wrapper that is more difficult to counterfeit or provides the user further assurance that the smoking article is authentic. . Furthermore, the smoking articles or wrappers described herein provide the manufacturer with additional flexibility and options for marking smoking articles, including the ability to generate invisible signs. These and other advantages will be apparent to those of ordinary skill in the art upon reading this disclosure.

  Any suitable smoking article or wrapper or housing for a smoking article can include the markings described herein. The term “smoking article” includes other articles in which smokable materials such as cigarettes, cigarettes, cigarillos and tobacco are ignited and burned to produce smoke. The term “smoking article” also refers to a smokable material such as, but not limited to, a smoking article that directly or indirectly heats the smoking composition, or a smoking article that does not burn or heat the smoking composition. Include articles that do not burn, but rather use air flow or chemical reactions to deliver nicotine or other materials from smokable materials.

  Usually, a smoking article is a form in which a user can grab an article and inhale smoke as desired. The smoking article includes a smokable composition, and often includes a filter disposed downstream of the smoking composition to filter components released from the smoking composition. Smoking articles typically have other elements such as an outer wrapper or a consumer-visible housing. The housing can include a smokable composition or a filter.

  The marking may be provided on or incorporated into the wrapper, housing or any other component of the smoking article that is visible to the consumer. Regardless of which component of the smoking article is provided with the marking, the marking is provided on the visible area of the smoking article. It is understood that the “visible region” is one region of the article that is visible to the user. The marking is preferably provided on the outer surface. Of course, the marking can be provided on a surface other than the outer surface. For example, when one or more external layers of a smoking article, or portions thereof, are transparent or translucent, or include windows, underlying layers, or portions thereof, viewed from the exterior of a fully assembled article be able to. Thus, in some embodiments, the underlying layer or portion thereof may provide a visible region. For the purposes of this disclosure, the term “substantially transparent” is used herein to describe a material through which at least a sufficient proportion of incident light can pass through so that it can be seen through the material.

  In embodiments, the component provided with the marking is a wrapper, such as a plug wrap, cigarette paper, chipping paper, or other suitable wrapper for a smoking article. Typically, wrappers for smoking articles are formed from other materials such as paper or cellulosic materials. In other embodiments, the wrapper is a film, such as a cellulose film, or other film, such as a polylactic acid film. The film can be substantially or completely transparent.

  If the marking is provided on a transparent or translucent component or part of a smoking article, the marking is visible from the outside through a transparent component or part, such as a transparent film wrapper, so the marking is transparent or translucent It can be provided on the inner surface of the element or part. The markings can also be provided on or incorporated into components underlying transparent components or parts.

  An optional marking may be provided on or in the smoking article or a component of the smoking article. For example, the marking can be in the form of an indicia. "Indicator" as used herein means an individual visual element or repeated element or pattern. The indicia may be in the form of a logo, text, image, pattern, or the like, or a combination thereof. As an example, the indicia may include a brand or manufacturer's logo that allows the consumer to identify the type and source of the smoking article. The indicia is generally perpendicular to the major axis of the smoking article or at any other angle other than parallel or perpendicular to the major axis of the smoking article. Can be aligned with the axis. If the indicia is aligned with the longitudinal axis of the smoking article, the indicia or portions thereof may be visible or disappear when the consumer turns the smoking article. If the indicia are aligned perpendicular to the longitudinal axis of the smoking article, the indicia or portion thereof is visible when the consumer rotates the smoking article about the longitudinal axis of the smoking article. It can disappear or disappear.

  The marking includes a combination of printed features and embossed features. The printed feature is preferably a printed pattern. In an embodiment, the patterns are adjacent to each other such that one color is on one side of the embossed feature and another color is on the other side of the embossed feature. Includes one and second colors. In some embodiments, the first or second color is provided by the color of the embossed material. That is, another color is not added to the area corresponding to the first or second color. In other embodiments, the color is added to the region corresponding to both the first color and the second color.

  Embossing and printing can occur in any order, such as printing first, embossing first, or printing and embossing simultaneously. In an embodiment, the marking is generated by first printing and then embossing. Any suitable printing process may be employed. For example, gravure printing (such as rotary gravure printing), offset printing, flexographic printing or digital printing (such as ink jet or laser jet printing) may be used. Any suitable material may be printed with inks, dyes, pigments, or the like.

  Any suitable embossing process may be employed. For example, plates or rollers with features corresponding to the desired embossing features may be used. It is possible to produce an embossed wrapper sheet prior to producing a smoking article, in which case the smoking article production equipment is embossed due to crushing by, for example, a roller or the like A surface relief pattern that matches the embossed pattern on the wrapper may be included to prevent damage to the processed features. In embodiments, embossing, printing, or both embossing and printing occur continuously in the manufacturing process of the smoking article.

  The combination of printing and embossing is not displayed when viewed from a particular angle, but is aligned to produce indicia that are visible when viewed from other angles. In an embodiment, the marking includes a printed pattern and an embossed pattern registered with the printed pattern on the first portion of the smoking article or wrapper and is offset from the printed pattern on the second portion of the smoking article or wrapper. As described above, the print pattern includes the first and second colors. The first and second colors are preferably sufficiently small in width to be printed adjacent to each other and mixed when viewed from a particular angle to produce a third color. Where the printed and embossed patterns are registered, a first color is provided on the first side of the embossed feature that is visible when viewed at a first angle. A second color is provided on the second side of the embossed feature that is visible when viewed at a second angle. Thus, where the printed and embossed patterns are registered, the first color is seen when the smoking article is viewed from a first angle, and the second color is the smoking article viewed at a second angle. Sometimes visible, the third color (mixed color) is visible when the smoking article or wrapper is viewed from a third angle.

  In the second part, if the embossed pattern is offset from the printed pattern, the second color is printed on one side of the embossed feature visible from the first angle. Thus, when viewed from the first angle, the second color can be seen from the first angle in the area where the embossed pattern and the printed pattern are not aligned. Looks like.

  In embodiments, the indicia is a wrapper or other component of the smoking article so that alternating strips of the first color and the second color, or other suitable alternating features, are adjacent to each other. Printed on top. The strip or other suitable feature may be straight, curved, wavy, or any suitable or desirable shape. Adjacent strips or features are narrow enough so that the first and second colors are not visually distinguishable and do not mix to produce a third color when viewed from the proper angle It is preferable. In embodiments, the width of adjacent strips or features is about 10 micrometers or less, such as about 5 micrometers or less, about 2 micrometers or less, or about 1 micrometer or less. Generally, the width of the strip or feature is about 50 nanometers or more, such as about 100 nanometers or more or 500 nanometers or more. In embodiments, the width of the strip is from about 1 micrometer to about 8 micrometers.

  Adjacent strips or features preferably have a color selected from a primary color (such as red, yellow or blue) or from a secondary color (such as green, orange or violet). As an example, if adjacent strips are sufficiently narrow and blue and yellow, the pattern or indicia generated by the strips will appear green when viewed from the proper angle.

  A printed first color is provided on the first side of the embossed feature that is visible when viewed from the first angle, and the printed second color is visible from the second angle. The vertex of the embossed feature is printed in the area where the embossed feature is registered with the printed pattern, as provided on the second side of the embossed feature. Preferably, the intersection of the first color and the adjacent printed second color is defined. In an embodiment, the color provided on one side of the embossed feature may be partially present on the other side of the embossed feature, so that between the two colors Transitions can be smoother, shade effects can be created, and movement effects can increase.

  The embossed feature may be of any suitable shape, such as having an upside-down V-shaped or U-shaped cross section. In an embodiment, the embossed feature is generally in the form of a prism.

  In an embodiment, the embossed feature has a ridge with a vertex. The vertices can be flattened, rounded, pointed, or the like. Edges with flattened or rounded vertices can be manufactured more easily than edges with sharp vertices. The top surface of the edge that is flattened or has rounded vertices may be provided with a third color, or may be provided with both a first color and a second color, whereby the first It can provide a totally mixed color when viewed from three angles. The boundary between colors can be approximately the center of the top surface. Also, this type of flattened or rounded vertices may give more tolerance in aligning the printed and embossed patterns. This is because the first and second color boundaries are not required to be accurately aligned as in the case of sharp vertices.

  The embossed features can be of any suitable height, width and length. In embodiments, the width, height, or both width and height of the embossed feature is no more than about 10 micrometers, no more than about 5 micrometers, no more than about 2 micrometers, or about 1 micrometers. And so on. Generally, the height, width, or both width and height of the embossed feature will be about 50 nanometers or more, such as about 100 nanometers or more or 500 nanometers or more. In embodiments, the height and width of the embossed feature is from about 1 micrometer to about 5 micrometers. The height and width may be the same or different. One or more of the embossed features may be of the same or different height and width. All of the embossed features are preferably of substantially similar height and width. The height and width of the embossed features are preferably substantially the same according to changes in the length of the features.

The embossed feature can have any suitable slope. For example, if the cross-sectional shape of the embossed feature is V-shaped, or if the embossed feature is prism-shaped, the side slope of the feature is about 20 degrees (°) to about 80 It can be in degrees (°). The inclination is preferably about 30 degrees (°) to about 70 degrees (°). The slope on one side may be the same as or different from the slope on the other side. The width of the printed strip is preferably approximately equal to the length from the base to the apex of the embossed feature.
As described above, in a predetermined position, the registration of the printed pattern or strip and the embossed feature is offset. The printing may be offset from the embossing, or the embossing may be offset from the printing. In any case, the length of the offset is preferably half or an integral multiple of the width of the printed strip. The length of the offset is preferably equal to the width of one printed strip. If the offset is equal to the width of one printed strip, a second color is provided on the first side of the embossed feature and the second color is visible from the first angle Become. If the offset is equal to half the width of one printed strip, the side of the embossed feature visible from the first angle will contain both the first and second colors . Thus, when viewed from the first angle, the second color is provided with a first color at half the width of the first side of the embossed feature and a second color at the half. As a result, it becomes visible as a mixed third color.

Embossed parts or areas where the printed and embossed features are in register with each other, as well as parts or areas where the printed and embossed features are offset The first side or face of the features to which is given is preferably visible from a first angle perpendicular to the first side. The second side or face of the embossed feature is preferably visible from a second angle that is perpendicular to the second side. Either a first angle and a second side of the embossed feature are visible at a third angle between the first and second angles, and either the embossed feature It is preferred that the colors on the sides of the side are mixed when viewed from a third angle. Only the first side of the embossed feature is visible from the angle range near the first angle, and only the second side of the embossed feature is visible from the angle range near the second angle It can be seen that both the first and second sides are visible from the range of angles near the third angle. In one example as also various embodiments, when viewed from the angle of the first angle from about + 25 degrees, only the first side of visible only or predominantly first side, about the second angle + 25 When viewed from a degree angle, only the second side or primarily the second side is visible, and when viewed from an angle of about +25 degrees from the third angle, both the first and second sides Preferably, the color becomes visible and a mixed color is produced.

  When incorporated into a smoking article, a marking comprising a combination of embossed features and printed features is when incorporated on or in a flat component (such as a wrapper) that is incorporated into the smoking article. It is understood that it can have different visual effects. For example, when incorporated on or in an article with a flat surface, the angle at which the different sides of the marking are visible will be substantially similar throughout the marking. However, when incorporated in or on a curved plane, or when the flat surface is curved, different portions of the marking can be seen from different angles with respect to the flat surface. For example, on a flat surface, the embossed feature pattern and the printed feature pattern are embossed at the location where adjacent strips of the first and second printed colors intersect. The first color is visible from the first angle and the second color is visible from the second angle. However, by bending a flat surface into a cylinder, the printed and embossed features are parallel to the long axis of the smoking article when viewed from a particular angle, A portion of the first color becomes visible, a portion of the mixed color becomes visible, and a portion of the second color becomes visible. However, if the printed and embossed features are generally perpendicular to the long axis of the smoking article, bending is more visible than when flat. There should be no significant effect on appearance.

  In an embodiment, the marking includes a portion adjacent to the patterned portion that includes a combination of embossed features and printed features. The combination of embossed features and printed features may be as described above. The alignment of the embossed features and the printed features may be registered throughout the patterned portion and may include the registered and offset portions as described above. As mentioned above, the patterned area allows the viewer to see both sides of the embossed feature so that the colors provided on either side mix to form a third color. Visible from a third angle. The part adjacent to the patterned part is colored with the same color as the first, second or third color. When viewed from an angle at which the same color as the part adjacent to the patterned part can be seen, the adjacent part and the patterned part are not visually distinguishable or substantially visually indistinguishable. However, when the color seen in the part with the pattern is viewed from an angle different from the color of the adjacent part, the part with the pattern can be visually identified from the adjacent part. Thus, the patterned portion may not be visible when viewed from the third angle, but may be visible when viewed from the first or second angle. In this way, the portion with the pattern can be in the form of an indicia, but it is not displayed when viewed from a specific angle, and can be visually identifiable when viewed from another angle. In embodiments, adjacent portions at least partially or completely surround the patterned portion. Alternatively, the patterned portion can surround at least partially or completely adjacent portions.

  The scales of the schematics presented herein are not necessarily to scale and are shown for illustrative purposes only.

  Referring now to FIG. 1, a smoking article 10 is illustrated. The smoking article 10 has a marking 99 that is visible to the consumer when viewed from an appropriate angle. As described above, the marking may be provided on or in the article 10, or a component thereof. In FIG. 1, the marking 99 is illustrated as three numbers “123”. The three numbers can be considered as a single marking or as three different markings.

  Referring now to FIG. 2, a partially deployed smoking article 10 (in this case, a cigarette) is illustrated. The smoking article 10 includes a tobacco rod 20 and a mouth end filter 30. Although illustrated as being separated by a gap, the tobacco rod 20 and the filter 30 can be adjacent to each other. The smoking article 10 includes a plug wrap 60 surrounding at least a portion of the filter 30 and a cigarette paper 40 surrounding at least a portion of the tobacco rod 20. Chipping paper 50 or other suitable wrapper surrounds plug wrap 60 and cigarette paper 40 as is generally known in the art. A marking (such as the marking 99 shown in FIG. 1) may be provided on the plug wrap 60, the cigarette paper 40, or the chipping paper 50. If the marking is provided at a location covered by the tipping paper 50 on the plug wrap 60 or cigarette paper 40, at least a portion of the tipping paper is transparent and the marking becomes visible to the consumer. The markings are preferably provided on a portion of the smoking article 10 that is not burned in use, such as a portion of the tipping paper 50 overlying the plug wrap 60 or filter 30.

  The smoking article illustrated in FIG. 2 is a cigarette and wrappers 40, 50 and 60 are cigarette paper, chipping paper and plug wrap, while other smoking articles vary in similar wrappers, components or colors It is understood that the surface can provide a marking.

  Referring now to FIGS. 3A-D, marking 99 is illustrated. 3A and 3B show perspective views generally viewed from the opposite side. The marking 99 includes an embossed feature 100 having an adjacent printed strip 110, 112 and an apex 102 at the intersection of the adjacent printed strip 110, 112. The printed strips are composed of alternating first colored strips 110 (eg, blue) and second colored strips 112 (eg, yellow). In the first region, the printed strips 110, 112 are on the first side 104 of the feature 100 where the first color strip 110 has been embossed and the second color strip 112. Align with the embossed feature 100 so that is on the second side 106 of the embossed feature 100. In this region, the first color 110 is visible when viewed from the first angle (Y). The second color 112 is visible when viewed from the second angle (X). When viewed from the third angle (Z), both sides 104, 106 of the embossed feature 100 are visible, thus both colors 110, 112 are visible. If the width of the colored strips 110, 112 and the embossed feature 100 is sufficiently small, the colors of the first and second strips 110, 112 are mixed to produce a third color (e.g. Blue + yellow = green).

  In the second region, the printed strips 110, 112 are not aligned with the embossed features 110. As illustrated in FIG. 3A, the printed and embossed features are not aligned to be offset by a distance (O) equal to the width of one printed strip, but this is illustrated It is also the width of the feature 100 that has been embossed in one embodiment. In this region, the second color 112 is provided on the first side 104 ′ of the embossed feature 100. Similarly, in the illustrated embodiment, the first color 110 is provided on the second side 106 ′ of the embossed feature 100.

  FIG. 3C illustrates an example of what can be seen when the marking 99 is viewed from a second angle (X). In this case, the first color 110 is visible in the unaligned area, while the second color 112 is visible in the aligned area.

  FIG. 3D illustrates an example of what can be seen when the marking 99 is viewed from a third angle (Z). The alternating first 110 and second 112 colored strips are visible even in unaligned areas. If the strip is sufficiently small in width, the color will appear as a mixed color. Thus, the features illustrated in FIG. 3C (first color 110 and background second color 112) are not visible when viewed from angle Z as illustrated in FIG. 3D, but are shown as angle X as illustrated in FIG. 3C. Visible when seen from.

  4A-D are different views showing that features of the marking 99 that are not visible in one view can be seen when viewed from different angles. FIG. 4A is a top-down view (viewed from top to bottom) of a marking 99 having alternating strips of different colors 110, 112, such as viewed from angle Z in FIG. In certain parts, such as those at lines BB ′ and DD ′, the embossed feature vertices 102 are aligned with the intersections of different colored strips 110, 112. The printed pattern and the embossed pattern are not aligned so that the vertex 102 is offset by the width of one printed strip at the part containing the cross section through line CC ′. As shown in FIGS. 4B-D, when different parts of the marking 99 are viewed from the same angle, depending on whether the part contains aligned or unaligned printed and embossed patterns I can see the color. 4B and 4D are cross-sections at lines BB ′ and DD ′, respectively, as shown, the embossed and printed features are aligned and the first angle The first color 110 is visible when viewed from. FIG. 4C is a cross-section at line CC ′, as shown, the embossed and printed features are not aligned (offset), when viewed from a first angle. A second color 112 is visible.

  Referring now to FIGS. 5A and 5B, there is shown a perspective view of a marking generally viewed from the opposite, where the colored portion 120 is a pattern with adjacent strips of the first color 110. Adjacent the raised portion, the second color 112 is aligned with the embossed feature 100. In the illustrated embodiment, adjacent colored portions 120 surround the patterned portions. The embossed feature 100 has a first side on which a first color 110 is provided and a second side on which a second color 112 is provided. The first color 110 is visible when viewed from an angle generally perpendicular to the first side of the embossed feature 100 (see FIG. 5B). When viewed from an angle generally perpendicular to the second side of the embossed feature 100, the second color 112 is visible (see FIG. 5A). When viewed from an angle between these two angles (eg, from top to bottom), the colors 110, 112 on either side of the embossed feature 100 are mixed and the same or substantially the same as the adjacent portion 120 Produces the same color. Thus, the indicia generated by the patterned area is invisible when viewed from a particular angle or becomes one with an adjacent part and visually distinguished from an adjacent part when viewed from a different angle. Is done.

  Reference is now made to FIGS. 6A and 6B, which show perspective views of the markings, generally viewed from the opposite. The markings are adjacent strips of the first color 110 and the second color 112 aligned with the embossed feature 100 or the first color 110 aligned with the embossed feature 100. And a patterned portion having a third color 114. The embossed feature 100 has a first side on which a first color 110 is provided and a second side on which a second color 112 or a third color 114 is provided. The first color 110 is visible when viewed from an angle generally perpendicular to the first side of the embossed feature 100 (see FIG. 6B). The second color 112 and the third color 114 are visible when viewed from an angle generally perpendicular to the second side of the embossed feature 100 (see FIG. 6A). When viewed from an angle between these two angles (eg, from top to bottom), the colors 110, 112 or 110, 114 on either side of the embossed feature 100 are mixed to provide a fourth or fifth, respectively. Colors are provided. The width of the colored features is thus small enough to be mixed when viewed from the proper angle. The width of the feature is about 10 micrometers or less, preferably about 5 micrometers or less, about 2 micrometers or less, or about 1 micrometer or less. Generally, the feature width is about 50 nanometers or more, such as about 100 nanometers or more, or 500 nanometers or more. In embodiments, the width of the strip is from about 1 micrometer to about 8 micrometers. In this way, the indicia generated by the patterned portion is not visible when viewed from the first angle, but is visible when viewed from the second angle. The indicia appears in different colors when viewed from an angle between the first angle and the second angle (such as from top to bottom in the illustrated figure).
