Description

Decorative structure {DECORATIVE STRUCTURE}

FIELD OF THE INVENTION The present invention relates to decorative structures or decorative products, such as lamps, which can provide a decorative structure, in particular an excellent three-dimensional effect and an appearance that attracts attention to a person. The invention also relates to decorative films useful for the production of such decorative structures.

Various types of vehicles, including passenger cars and trucks, are provided with red stop and tail lights that turn on with the use of brakes, yellow turn signals that turn on with the use of turn signals, and colorless reversing lights that turn on with reverse operation. . Each vehicle lamp usually includes a housing having a light emitting opening provided in front of it, a lamp cover shaped like a plate or lens covering the light emitting opening, and a light source disposed in the lamp chamber formed by the housing and the lamp cover. The inner wall of the housing is provided with a reflective layer integrated with the inner wall or with a standalone reflector. In such a vehicle lamp, when the light source is turned on, the direct light from the light source and the light reflected by the inner wall of the housing are emitted through the lamp cover to the outside of the lamp to perform the desired illumination function.

In recent years, such vehicle lamps are required to have an illumination function of the illuminated state as well as an improved appearance of the non-illuminated state in the daytime. As one way to meet the needs of these users, it is common that the light non-emitting portion of the lamp cover is provided with a plate-shaped reflecting surface such as a reflector disposed in the lamp chamber so that the appearance of the lamp through the lamp cover has a sharpness and perspective. Is adopted. In addition, it is also adopted that a decorative product having the same appearance as this lamp but without any light source is provided in parallel arrangement with the lamp.

Furthermore, there is an idea that the appearance of a decoration formed by providing a reflecting surface installed in the lamp cover as described above is improved in design and distinguished from another decoration. The purpose of almost all ideas is to add uneven patterns to the reflective surface of the housing or lamp cover to obtain a unique design derived from diffuse reflection of light. However, only adding the uneven pattern limits the deformation of the appearance to be obtained.

For this reason, Japanese Unexamined Patent Publications (close up) Nos. 11-66906 and 11-66907 are designed to further improve the appearance by cooperation of the decorative pattern between the pattern and the reflective surface of the housing (shift of eye line). To be formed by a combination of evaporation, color printing and convex printing. 1 shows one embodiment of a vehicle lamp disclosed in Japanese Unexamined Patent Publication (Koikai) No. 11-66907. Such a lamp is provided with a front lens 52 covering the opening of the lamp housing 51 and a light source (bulb) 54 inserted into the socket 53. The front lens 52 includes a light emitting portion L and lens dummy portions D and D '. In addition, a reflector 5 which reflects light from the light source 54 is arranged on the inner wall of the lamp housing 51. Such a lamp is provided with a printing sheet 56 along the inner side of the front lens 52. The printing sheet 56 is a transparent and color printing film having a predetermined pattern is printed on the inner surface of the transparent plate, the evaporation film facing the printing film is formed on the outer surface of the plate and the transparent convex printing layer is the outer surface of the evaporation film It is characterized by being formed on the surface.

The vehicle lamp shown in the figure is effective in that light colored light can or may not be observed depending on the pattern of the evaporation film due to the movement of the eye, but still provides a three-dimensional effect that can promote the improvement of the design. Can't be reached. Furthermore, since the structure of the printing sheet is complicated, its manufacturing process is complicated, and its increase in manufacturing cost cannot be avoided. For example, the process of forming the evaporation film on the resin plate to form a pattern requires a masking material having the same pattern as the printing film as well as the step of superimposing the convex print layers on the evaporation film in the same pattern. Furthermore, since a printing sheet different from the front lens must be disposed inside the front lens, it prevents the emission of light from the light source necessary to satisfactorily transmit the front lens. In addition, since the printing sheet is disposed closer to the reflector than the front lens, there is less three-dimensional effect derived from the distance between the printing sheet and the reflector. Furthermore, when the plate of the printing sheet has a three-dimensional curved surface, the formation of the pattern on the surface by evaporation or printing is so limited that it cannot be realized.

Furthermore, the decorative film preferably further comprises an adhesive layer made of an acrylic adhesive.

Furthermore, the decorative film preferably further comprises a transparent layer as its outermost layer.

In the following, the decorative structure according to the present invention will be further described by specifically taking a vehicle lamp structure and a vehicle decorative product as an example. It goes without saying that the present invention is not limited only to these examples.

The lamp structure according to the present invention can be used in various fields, and is particularly useful as a vehicle lamp structure. The lamp structure can be used in various fields as lighting means, indicating means, signal means and the like. The lamp structure is usually provided with a lamp cover made of a light source, a housing capable of reflecting light from the light source on the inner wall, a light emitting opening and a light transmitting resin covering the light emitting opening. One example of such a lamp structure is, but is not limited to, headlights, fog lights, vehicle lights, stop lights, tail lights, turn signals, reversing lights, and the like. Furthermore, the lamp structure can be a combination of a plurality of lamps, which can be used, for example, as a rear combination lamp at the rear of the vehicle or a front combination lamp at the front of the vehicle. Further, although the decorative structure according to the present invention is usually used in combination or independently with such a lamp structure for improvement of design or the like, a decorative structure which is not intentionally provided with a light source is particularly included within the scope of a vehicle decorative product. Vehicles provided with a lamp structure include, but are not limited to, passenger cars, recreational vehicles, buses, trucks, and the like. Specifically, the lamp structure is suitable for a passenger car because of improving the design, visibility and the like.

5 shows an exemplary configuration of a vehicle lamp structure according to the present invention. The lamp structure 30 includes a lamp housing 1 and a lamp chamber formed by a lamp cover 2 covering a light emitting opening (emission area) L in front of the lamp housing 1.

The lamp chamber may have two or more threads as necessary. Each yarn may be independent of each other or may be in communication with each other. The lamp chamber is usually provided with a light source 4 of appropriate intensity inserted into a socket (not shown). In some cases, the light source can be omitted from some of the threads. The inner wall 1a of the housing has a mirrored exterior surface of a reflective film structure, such as a concave mirror, in which light from the light source 4 is reflected in one direction. Instead of an inner wall having such a mirrored exterior surface, light reflecting means (usually reflectors), which are not shown in the drawings such as concave mirrors, may be provided. The light source 4 may have a cap colored in a predetermined color as needed. When a colored cap is used, a colorless cover can be used instead of the colored cover. For example, a yellow cap may be placed on the turn signal. The lamp cover is provided with a non-light transmitting area, that is, a light non-emissive area, which is substantially independent of the emission of light from the light source 4, in order to improve the design and the like, which are particularly recent. This is not an exception to the lamp cover according to the invention, since the non-transmissive area S is provided as shown in the figure. Furthermore, the multilayer decorative film 10 according to the present invention is attached to the non-transmissive region S. In the example shown in the figure, the decorative film 10 is attached to the inside of the lamp cover 2, but may be attached to the outside thereof in the present invention.

In the lamp structure according to the invention, a mirror-like facade should be provided on the inner wall of the lamp structure. The mirror appearance surface means a reflection surface capable of substantially reflecting an opposing object such as a mirror, and the reflectivity of the mirror appearance surface may be freely changed. That is, the mirror-like exterior surface is not always required to be flat like a mirror, and may be a reflective surface of the same height capable of reflecting a shape to some extent and distinguishing colors and images. The specular appearance surface can be formed by a variety of methods and can usually be formed by metal evaporation, metal plating, finishing of metal containing coatings, adhesion of plating appearance transfer foils or films, and the like. Otherwise, the mirrored face may be formed by providing a thin plate of metal, a metallic face sheet or film, or a plate to which the metallic face sheet or film is attached in the space on the side of the inner wall of the housing.

Furthermore, in the lamp structure according to the present invention, the light emitting openings (light emitting areas and light non-emitting areas adjacent thereto) in the lamp chamber are covered with a lamp cover. The lamp cover is preferably made from the light transmitting resin by an injection molding method or another molding method. The shape of such a lamp cover has a shape and size suitable for covering at least the light emitting surface, but is typically circular, rectangular or square, and in some cases may be a unique shape such as oval or L-shaped.

The lamp cover can be colorless and colored as necessary, ie according to the hue of the light emitted therefrom. When the lamp chamber is composed of a combination of two or more threads, the lamp cover of each thread can be colored in different colors. For example, the cover of a stop tail light required to emit red light is colored red, and the cover of a turn signal required to emit yellow light is colored yellow. Alternatively, instead of a colored cover, a colorless cover can be used and the lamp can be covered with a colored cap. By applying such an alternative method in addition to the above-described method, a different appearance can be realized when a colored cover is used. Of course, the cover of the colorless reversing light is not required to be colored.

Colorless or colored lamp covers can be advantageously formed from selective light transmitting resins by molding methods. Suitable molding methods include conventional methods such as injection molding methods or vacuum molding methods. Further, the raw resin used to form the lamp cover includes, but is not limited to, styrene resin, rigid PVC, acrylic resin, polycarbonate resin, and the like. Specifically, acrylic resins can be advantageously used because they can be advantageously colored with good strength and transparency. In some cases, glass plates or the like can be used as the lamp cover.

When colored lamp covers are made, an appropriate amount of coloring material may be mixed into the raw resin as described above. Suitable coloring materials include, but are not limited to, perylene pigments, azo pigments, pigments such as iron oxide, or dyes such as chinoputarone dyes, azo dyes, exponential azo dyes, anthraquinone dyes, benzopyrene dyes (from color indexes, respectively). ). For the practice of the present invention, dyes such as azo dyes, exponential azo dyes and the like can be used particularly advantageously because of the good distribution of the resin, light emission, transparency and weather resistance.

When the lamp cover is manufactured, additives conventionally used in the field of injection molding can be mixed into the raw resin in addition to the coloring material. Suitable additives include, for example, ultraviolet absorbers, light stabilizers, heat stabilizers and the like. For example, suitable ultraviolet absorbers include, but are not limited to, benzotriazoles, benzophenones, zipeniruacrylates, amine ultraviolet absorbers, and the like. In addition, the amount of such ultraviolet absorber to be added may vary, but is usually in the range of approximately 0% to 3% by weight relative to the total amount of the raw resin.

The lamp cover is usually shaped like a flat plate and has a flat surface, but may have an uneven pattern formed on its inner surface (side of the light source). Thus, the uneven pattern may bring about the function of the lens or the retroreflective function. The uneven pattern may be previously formed on the mold, for example, and printed on an object (lamp cover) formed by the mold in the forming step. Furthermore, a lamp cover having a three-dimensional curved surface or the like can be used for the improvement of the design. The thickness of the lamp cover is usually several millimeters but is not limited thereto.

The lamp cover is provided with a decorative film attached to a light non-emissive area, that is, a non-light transmissive area, in which light emitted from a light source disposed in the lamp chamber does not transmit or need to be transmitted. Although the light non-emitting area of the lamp cover can be provided in various areas, it is usually provided in an area around the light emitting opening of the lamp chamber. That is, the light non-emission area is a spare area such as a headlamp, a turn signal, a reversing light, and the like. Such light non-emissive areas may take an optional shape depending on the area around the light emitting apertures.

In the lamp cover, by attaching the specific decorative film described below to the portion of the lamp cover that does not affect the movement of light from the light source, a significant improvement in appearance and / or design can be realized while meeting the requirements of the vehicle operating rules. . Specifically, according to the present invention, an appearance with a remarkable three-dimensional effect and a novel design that attracts human attention can be obtained. As will be understood from the following description, the three-dimensional effect is highly dependent on the uniformity of the light shielding portion of the pattern of the decorative film and the part observable from the light transmitting portion of the pattern.

The decorative film according to the present invention comprises a metal coating having (1) a pattern derived from the combination of the light transmitting portion and the light shielding portion and (2) having a metallic appearance, preferably a metallic gloss appearance, the same or similar to the inner wall of the lamp structure; Colored layers with selective color tone; Or a multilayer decorative film including at least one appearance modifying layer including a combination thereof.

The decorative film may further include a bonding layer, a support layer, a base layer, an adhesive layer, a transparent layer and the like as necessary.

The appearance modifying layers may be used alone or in combination of one or more. When two or more appearance modifying layers are used, the arrangement of the appearance modifying layers can be freely changed. In the details of the layer construction of the decorative film, when attached to the inner surface of the lamp cover, the metal coating is preferably attached to the inner surface of the lamp cover in such a way that it is located closer to the lamp cover than the colored layer.

6 is a cross-sectional view of one example of a decorative film having the above-described layer attached to the inner surface of the lamp cover (some patterns are omitted for the sake of brevity). The decorative film 10 shown in the figure is the adhesive layer 14, the first intermediate layer 11, the first appearance modification layer (metal coating) 15, the second intermediate layer 12 in the order observed from the lamp cover 2. ), A second appearance modification layer (colored layer) 16, and a third intermediate layer 13. The first and second appearance modifying layers 15, 16, ie the metal coating and the colored layer, may be interchanged, and both of the first and second appearance modifying layers 15, 16 may be colored, or the metal coating or One of the colored layers may be omitted. The first, second and third intermediate layers 11, 12, 13 are optional and can act as bonding layers, support layers and base layers, respectively. These intermediate layers can be single layers or multiple layers including two or more layers. Furthermore, the first and third intermediate layers 11, 13 are in principle colorless and transparent and should not affect the design resulting from at least the metal coating 15 and the colored layer 16.

Furthermore, the decorative film is also preferably attached to the outer surface of the lamp cover. In this case, the decorative film is attached to the outer surface of the lamp cover in such a way that the metal coating is located farther from the lamp cover than the colored layer.

7 is a cross-sectional view of an example of a decorative film having the above-described layered structure attached to the outer surface of the lamp cover (some patterns are omitted for the sake of brevity). The decorative film 10 shown in the drawing is the adhesive layer 14, the first intermediate layer 11, the second appearance modification layer (colored layer) 16, and the second intermediate layer 12 in the order observed from the lamp cover 2. ), A first appearance modification layer (metal coating) 15, a third intermediate layer 13, and a transparent layer (surface layer) 17. The second appearance deforming layer (colored layer) 16 also serves as the first intermediate layer 11. The first and second appearance modifying layers 15, 16, ie the metal coating and the colored layer, may be interchanged, and both of the first and second appearance modifying layers 15, 16 may be colored, or the metal coating or One of the colored layers may be omitted. The first, second and third intermediate layers 11, 12, 13 are optional and can act as bonding layers, support layers and base layers, respectively. These intermediate layers can be single layers or multiple layers including two or more layers. Furthermore, the first and third intermediate layers 11, 13 are in principle colorless and transparent and should not affect the design resulting from at least the metal coating 15 and the colored layer 16.

The decorative film has a combination of the light transmitting portion and the light shielding portion and has an optional pattern derived from the combination thereof. Suitable patterns are formed of, but are not limited to, stripes, round holes, dots, square holes, lattice holes, checkers, and the like. Patterns formed by distributing thin lines, which are variations of stripes, are also effective. If desired, a combination of these patterns can be added to the decorative pattern. These patterns may constitute a light transmitting portion or may constitute a light shielding portion. The size of each pattern can be freely changed depending on the design effect having the desired appearance.

8A, 8B and 8C are plan views showing examples of possible patterns of decorative films, respectively. The decorative film 10 of Fig. 8A has a stripe-like pattern formed by repeating the light shielding portion 10A having a stripe like shape and the light transmitting portion 10B having a stripe like shape at the same pitch p. The decorative film 10 of Fig. 8B is a pattern of round holes formed by repeating the light transmitting portions 10B having the same shape as the round holes at the same pitch p and arranging the light shielding portions 10A between the light transmitting portions 10B. Has The decorative film of Fig. 8C has a checker-like pattern formed by repeating the square light shielding portion 10A and the square light transmitting portion 10B having the same size at the same pitch p.

In the decorative film according to the present invention, (1) the opening ratio formed by the area ratio of the light transmitting parts to the whole decorative film is 10% to 99%; (2) The ratio d / p of the distance d (see Fig. 2) between the decorative film and the inner wall of the housing to the pitch p of the decorative film (see Fig. 8) between the light shielding portion and the light transmitting portion is shown. It is preferably at least 1/40, more preferably the opening ratio is in the range of 20% to 97% and the ratio of the distance d to the pitch p is at least 1/20, and the opening ratio is in the range of 35% to 90%. It is particularly preferred that it is in the range and the ratio of the distance d to the pitch p in the range of 1/3 to 5/1. When the opening ratio is less than 10%, the three-dimensional effect to be induced is small. Conversely, when the opening ratio is greater than 99%, the desired advantage can no longer be obtained. Furthermore, even when the ratio of the distance d to the pitch p is smaller than 1/40, the three-dimensional effect to be induced becomes small.

In the decorative film according to the present invention, the metal coating serving as the appearance modifying layer is the same as or similar to the reflecting film provided on the inner wall of the housing constituting the lamp chamber or the reflecting film (if present) embedded inside the housing and It is usually formed to have a metallic appearance and in particular a metallic glossy appearance. The metal coating can be formed by various methods. Metallic coatings are pearl micas in which brightly colored inks and / or brightly colored materials are distributed by evaporation or sputtering of metallic materials such as aluminum, chromium or tin, by coating of resins in which metallic powders such as aluminum powder are dispensed. It may be formed by printing or finishing (including an electrostatic finish) or other method of paint, such as paint. Furthermore, the metal coating can be formed by coating, resin extrusion or attachment of a film or sheet with the desired light reflection appearance. The thin film forming method used in the above-described method preferably brings about the desired light reflection appearance in addition to the excellent weather resistance required for the lamp cover. The thickness of the metal coating can vary widely depending on the desired design effect and the like, but is usually in the range of about 5 μm to 500 μm, more preferably in the range of about 20 μm to 100 μm.

Furthermore, colored layers used in combination or independently of metal coatings can also be formed using various conventional thin film forming methods such as metal coatings. That is, the colored layer can be formed by printing, finishing (including electrostatic finish), or the like, of an ink or paint having a predetermined color tone, or by coating, resin extrusion or adhesion of a film or sheet having a predetermined color tone. Inks and paints may contain light colored materials, such as pearl powder or metal powder, or other additives. The colored layer forming material used in this method preferably has excellent weather resistance and the like required for the lamp cover in addition to the coloring properties. According to the knowledge of the inventors, the colored layer has more significant contrast, and therefore is more effective when formed to have a darker color tone. The thickness of the colored layer can vary widely depending on the desired design effect and the like, but is usually in the range of about 5 μm to 500 μm, more preferably in the range of about 20 μm to 100 μm.

More specifically, the colored layer may be formed of a colored film by using a plastic material such as polyester film, polyethylene film, polycarbonate film, vinyl chloride film, acrylic film, polyurethane film, polyolefin film, or inline fluoride film in one embodiment. It may be formed in the form. Colored films useful for light shielding can be formed by coloring the transparent film with optional coloring materials such as dyes or brightly colored materials. Suitable dyes include, for example, colorless dyes such as titanium oxide, carbon black and the like and inorganic and organic colored dyes.

Furthermore, sufficiently brightly colored materials include aluminum flakes and pearl powder.

Furthermore, the metal coatings and colored layers may further have patterns, images, letters, and the like. Thus, the design of the decorative film is further improved.

The decorative film according to the present invention is preferably provided with an intermediate layer interposed between the colored layer and the metal coating or arranged in another optional position to increase its bending strength and bonding strength. The intermediate layer can, for example, act as a bonding layer, support layer or base layer. Suitable intermediate layers are bonding layers made of polyurethane resin and the like or base layers made of polyester resin. These intermediate layers can be single layers or multiple layers including two or more layers.

The decorative film according to the invention generally further comprises an adhesive layer to be attached thereto. The adhesive layer used herein may be formed by using an adhesive tape or the like, which is commonly used in the field of adhesives such as a reduced pressure form, a thermal form, a photocurable form and the like. Suitable adhesives include, for example, acrylic adhesives, polyurethane adhesives, polyester adhesives, and the like, and especially acrylic adhesives can be advantageously used when weather resistance and the like are considered. The thickness of this adhesive layer can vary widely, but is usually in the range of approximately 10 μm to 500 μm, more preferably in the range of about 20 μm to 100 μm. When the thickness of the adhesive layer is smaller than 10 mu m, satisfactory adhesive force can be obtained. In contrast, when the thickness of the adhesive layer is larger than 500 µm, the overall thickness of the decorative film becomes very large. In fact, in this case, when the adhesive layer is attached to the outer surface of the lamp cover, the adhesive layer is in a protruding state from the lamp cover, thereby providing a sense of incompatibility. Furthermore, this adhesive layer is preferably used as a release liner attached thereto for easy handling of the lamp cover and for attachment of the decorative film to the lamp cover.

The decorative film preferably further comprises a transparent layer as its outermost layer when attached to the outer surface of the lamp cover. The transparent layer preferably has weather resistance and heat resistance in addition to transparency which is basically essential from the viewpoint of acting as a protective film. Furthermore, the transparent layer preferably has good adhesion to its underlying layer. Resins suitable for forming the transparent layer include, but are not limited to, polyester resins, polyethylene resins, polycarbonate resins, vinyl chloride resins, acrylic resins, polyurethane resins, polyolefin resins, fluorine resins (PVdF, ETFE, etc.), and the like. . These resins can be used in the form of mixtures or copolymers as desired. Furthermore, the transparent layer can provide gloss to the lamp cover to improve the appearance of the lamp cover.

It is preferred that the ultraviolet absorbent is mixed into the transparent layer to increase the weather resistance of the decorative film. Suitable ultraviolet absorbers include, but are not limited to, benzotriazole ultraviolet absorbers, benzophenone ultraviolet absorbers, cyanoacrylate ultraviolet absorbers, and the like.

Furthermore, the thickness of the transparent layer can vary widely depending on the desired effect or the like, but is usually in the range of about 1 μm to 500 μm, more preferably in the range of about 10 μm to 100 μm. When the thickness of the transparent layer is smaller than 1 µm, it cannot act as a protective film. In contrast, when the thickness of the transparent layer is larger than 500 µm, the total thickness of the decorative film becomes very large.

The light shielding portion of the appearance modifying layer may be formed of a light shielding material. For example, after a material having a shape such as a sheet or a film having light shielding properties in its entirety is prepared, an opening of a light transmitting portion having a shape such as a stripe, a lattice, a dot, or the like may be produced in the material, or a slit is produced in the material by punching or the like. Can be. Further, in the step of forming the appearance modifying layer in the shape of a film, the coloring material is mixed into the raw film to produce the appearance modifying layer having the light shielding portion formed in a predetermined pattern. Further, the light shielding portion may be formed by attaching a colored film having a predetermined pattern to the transparent film or by printing a colored layer having a predetermined pattern on the transparent film. The obtained decorative film can be attached to the surface of the lamp cover by using a carrier tape as required or by compression, thermal lamination or the like. According to the present invention, since it is not required to form a decorative pattern by evaporation, printing or the like through complicated work, the workability is excellent and the utility is extremely large.

The decorative structure according to the invention covers the lamp structure described above as well as other lamp structures (no light source in the lamp chamber) or other decorative structures. Other decorative structures include, for example, decorative products attached to vehicles, household appliances, toys, etc. to be used. For example, vehicle products include, but are not limited to finishers, varnishes, emblems, chenilles, and the like.

9 is a cross-sectional view of an example of a vehicle decorative article according to the present invention (predetermined pattern is omitted for simplicity). The vehicle decorative product 40 shown in the figure is an emblem comprising a base material 41, a decorative film 10 and a transparent intermediate member 45 interposed between the base material 41 and the decorative film 10. The vehicle name logo name is printed by patterning on the mirror-shaped exterior surface 41a of the base material 41. The decorative product 40 is attached to a predetermined portion of the vehicle 47 through the adhesive layer 48.

The decorative film 10 is the adhesive layer 14, the 1st intermediate | middle layer 11, the 2nd external appearance deformation | transformation layer (colored layer) 16, the 2nd intermediate | middle layer 12, the 1st in the order observed from the base material 41. The appearance modification layer (metal coating) 15, the 3rd intermediate | middle layer 13, and the transparent layer (surface layer) 17 are included. The first and second appearance modifying layers 15, 16, ie the metal coating and the colored layer, may be interchanged, and both of the first and second appearance modifying layers 15, 16 may be colored, or the metal coating or One of the colored layers may be omitted. The first, second and third intermediate layers 11, 12, 13 are optional and can act as bonding layers, support layers and base layers, respectively. These intermediate layers can be single layers or multiple layers including two or more layers. Furthermore, the first and third intermediate layers 11, 13 are in principle colorless and transparent and should not affect the design resulting from at least the metal coating 15 and the colored layer 16.

There is no restriction on the base material that can be freely determined according to the type of the decorative product in the vehicle decorative product shown in the figure. Suitable base materials are, for example, films or sheets made of plastic materials such as polyester resins or polyurethane resins, or metal foils, metal sheets and the like, in some cases, suitable base materials can be, for example, plastic plates, metal plates and the like. These base materials may be used as they are or may have an adhesive layer on a side other than the side facing the decorative film. Further, the base material may be omitted, and the mirror-like exterior surface to be provided on the base material may be formed on one side of the transparent member described below.

The decorative article according to the invention requires that a mirror-like facade is provided on one side of the base material or on one side of the transparent intermediate member as required. The mirror-like exterior surface may be basically the same as the lamp structure described above, so it is not always required to be flat like a mirror, but may be a reflective surface that can reflect the shape to some extent and distinguish colors and images. . Furthermore, the mirror-like exterior surface can be formed, for example, by metal evaporation, metal plating, coating of metals containing paint, adhesion of plated exterior transfer foils or films, and the like, such as lamp structures. In addition, the mirror-like exterior surface may have a pattern, an image, a character, and the like.

The transparent intermediate member disposed between the base material and the decorative film, which may be omitted, may be formed of various light transmitting materials. Suitable light transmitting materials for forming the intermediate member are, for example, polyester resins, polyurethane resins, polyvinyl chlorides, acrylic resins, polycarbonate resins, polystyrene resins, melamine resins, polyolefin resins (polypropylene, polyethylene, EEA, AEE, EVA). Etc.) and fluorine resins (PVdF, ETFE, etc.). These resins can be formed into a desired shape and size by an injection molding method, a thermopressing method, a casting method, an extrusion molding method, a shaving method, or the like. Furthermore, the intermediate member may include other light transmitting materials of inorganic material such as glass, for example, instead of the resin as described above.

The intermediate member is usually colorless and transparent, but can be colored according to the design effect to be achieved and the like, and particularly preferably colored in pale color. If the base material is not used as described above, a mirrored exterior surface can be formed on one side of this intermediate member by the same method as described above.

The thickness of the intermediate member is usually several mm but is not limited thereto. However, the intermediate member may have a thickness smaller than 1 mm or larger than 10 mm depending on the type of decorative product.

The decorative film used in combination with the intermediate member has basically the same configuration as that used in the lamp structure described above, and thus has a metal coating, a colored layer, or a combination thereof as an appearance modification layer.

The metal coating, which is one member of the appearance modifying layer, is usually formed to have an appearance that is the same as or similar to the underlying layer of the decorative film and which is usually of metallic appearance, in particular of metallic gloss appearance. Such metal coatings can be printed or finished in a variety of methods as described above, such as by evaporation or sputtering of metal materials, coating of resins in which the metal powder is dispensed, or the like, in light colored inks and / or paints in which the light colored materials are dispensed It can be formed by. Furthermore, the metal coating can be formed by coating, resin extrusion or attachment of a film or sheet with the desired light reflection appearance. The thickness of the metal coating can vary widely depending on the desired design effect and the like, but is usually in the range of about 5 μm to 500 μm, more preferably in the range of about 20 μm to 100 μm.

Furthermore, colored layers used in combination or independently of metal coatings can also be formed using various conventional thin film forming methods such as metal coatings. That is, the colored layer can be formed by printing, finishing, or the like of ink or paint having a predetermined color tone, or by coating, resin extrusion or adhesion of a film or sheet having a color tone. Inks and paints may contain light colored materials, such as pearl powder or metal powder, or other additives. The thickness of the colored layer can vary widely depending on the desired design effect and the like, but is usually in the range of about 5 μm to 500 μm, more preferably in the range of about 20 μm to 100 μm.

Metallic coatings and colored layers used in decorative films may further have patterns, images, letters and the like. Thus, the design of the decorative film is further improved.

The decorative film is preferably provided with an intermediate layer interposed between the colored layer and the metal coating or disposed at another optional position to increase its bending strength and bonding strength. The intermediate layer can, for example, act as a bonding layer, support layer or base layer. Suitable intermediate layers are bonding layers made of polyurethane resin and the like or base layers made of polyester resin. These intermediate layers can be single layers or multiple layers including two or more layers.

The decorative film generally further comprises an adhesive layer to adhere thereto. The adhesive layer used herein may be formed by using an adhesive tape or the like, which is commonly used in the field of adhesives such as a reduced pressure form, a thermal form, a photocurable form and the like. Suitable adhesives include, for example, acrylic adhesives, polyurethane adhesives, polyester adhesives and the like. The thickness of this adhesive layer can vary widely, but is usually in the range of approximately 10 μm to 500 μm, more preferably in the range of about 20 μm to 100 μm.

The decorative film preferably further comprises a transparent layer as its outermost layer when attached to the outer surface of the lamp cover. The transparent layer preferably has weather resistance and heat resistance in addition to transparency which is basically essential from the viewpoint of acting as a protective film. Furthermore, the transparent layer preferably has good adhesion to its underlying layer. Resins suitable for forming the transparent layer include, but are not limited to, polyester resins, polyethylene resins, polycarbonate resins, vinyl chloride resins, acrylic resins, polyurethane resins, polyolefin resins, fluorine resins (PVdF, ETFE, etc.), and the like. . These resins can be used in the form of mixtures or copolymers as desired. The thickness of the transparent layer can vary widely depending on the desired effect and the like, but is usually in the range of about 1 μm to 500 μm, more preferably in the range of about 10 μm to 100 μm.

The above-mentioned transparent layer may be omitted as required, or a film or sheet-like material such as an intermediate member may instead be attached to or superimposed on the transparent layer. In this case, a novel design effect can be obtained which is not obtained only by the transparent layer.

As described above, the decorative film used in the decorative structure includes a multilayer film which can provide a special appearance according to a pattern formed by hole making or the like, and has a housing having a reflecting surface formed by metal evaporation or the like or a reflector And a lamp structure having a lamp cover or a lamp cover of a decorative product having a structure similar to that of the lamp structure. The decorative film has a metallic gloss appearance as formed by aluminum evaporation on its side which is observable from the outside, and has a colored appearance on its opposite inner side.

When the lamp structure of the decorative article having such a configuration is observed from the outside, the metallic luster of the decorative film can be observed on the portion (film portion) provided with the decorative film. On the contrary, the reflective surface of the housing or the like can be observed through the portion (non-film portion) in which the decorative film is not provided. Further, when the non-film portion is reflected on the reflective surface, it is recognized as the metallic glossy surface. On the contrary, when the film portion is reflected on the reflective surface, the color tone of the colored layer is recognized. As such, the appearance changes advantageously with time. In the former case, since the metallic appearance of the decorative film, the appearance of the reflective surface of the housing, and the like are substantially similar to each other, all of the appearances are observed as a continuous appearance such that the difference in depth of the reflective surfaces is not detected. On the contrary, in the latter case, since the appearance of the metallic glossy surface of the decorative film is different from the colored surface of the colored layer, a sense of depth with respect to the degree of reciprocating distance between the decorative film and the housing may be generated. As such, when observations are performed with varying degrees of continuity, the design surface appears to be visible, disappearing, or increasing or decreasing the area of the design surface, representing a length that is twice the actual depth. As such, an appearance with previously unknown high quality and novel design can be obtained. The decorative film may be attached to one of the inner and outer surfaces of the lamp cover when used for the lamp structure, but if the lamp cover is colored, the decorative film attached to the inner surface can be observed evenly from various angles, so that the outer surface It provides a better design than that attached to.

The present invention will be described with reference to examples. It should be understood that the present invention is not limited to these examples.

Examples 1-15 and Comparative Examples 1-3

A laminated film having the following layer configuration was produced.

Adhesive layer (transparent acrylic adhesive, 35 μm thick) / metal coating (tine evaporation layer, 0.5 μm thick) / base layer (polyurethane film, 50 μm thick) / black colored layer (polyurethane film, 5 μm thick) / transparent layer ( Transparent polyurethane film, 20 μm thick)

This laminated film was cut into a few pieces having different widths as shown in the table, and these pieces were arranged to have different pitches (periodic values of alternating light transmitting portions and light shielding portions) p, and in this state These pieces were integrated by a carrier tape with an adhesive. The resulting decorative film of stripe-like shape was attached to a colorless and transparent acrylic plate (2 mm thick) and pressed.

The aluminum evaporation film was attached to one side of the acrylic resin panel having the same shape and size as the acrylic plate described above so as to be in a mirror state, and the acrylic plate manufactured in the previous process was acrylic so that the surface of the decorative film faced the aluminum evaporation film. It was arrange | positioned apart from the resin panel by the distance d (refer Table 1). In Example 15, a 10 mm thick glass plate was interposed between the acrylic plate and the acrylic resin panel instead of placing the acrylic plate at a distance d from the acrylic resin panel.

When the depth appearance of the aluminum evaporation surface of the acrylic resin panel was observed from the acrylic plate side, observation results as described in Table 1 were obtained.

Example 16

A decorative film having a layer structure as described in Table 2 was produced. This decorative film is designed to be attached to the inside of the lamp cover.

Lamp cover Adhesive layer (acrylic adhesive) 40 μm thick Colorless and transparent Metallic Coating (Aluminum Evaporation Film) 0.5 μm thick Plating tint Base layer (polyester film) 50 μm thick Colorless and transparent Colored layer (polyurethane) 10 μm thick black

Colored layers, base layers and adhesive layers have been produced by using products that are tried and applied outdoors in the field of vehicle exterior features.

The laminated film obtained was cut into a few pieces having a width of 4 mm, these pieces were arranged at 4 mm intervals, and in this state these pieces were integrated by a carrier tape having an adhesive. A decorative film of the same shape as a stripe was obtained.

The decorative film described above was attached to a rear combination lamp of a commercial car, the inner side of which had a plating tint by evaporation of aluminum, its front and rear had a smooth cover, and the inside thereof could be observed. In this example, the decorative cover was compressed and fixed to the area of the inner side of the tail lamp red lamp cover (thickness of the lamp cover: about 2 mm, distance from the inner side of the lamp compartment to the receiving surface: about 6 mm) Is limited to the light non-emitting region around the light emitting portion. The appearance of the obtained lamp structure was observed when the lamp was not turned on while varying the viewing angle vertically in the longitudinal direction of the stripe, and the following results described with reference to Figs. 10A, 10B and 10C were obtained.

When the lamp is observed from its front side as shown in Fig. 10A (viewing angle: 0 °), the metal evaporated exterior surface of the decorative film 10 can be observed through the red lamp cover 2, and the housing ( The metal evaporation surface of 1) can be observed through the light transmitting portion. However, since both the metal evaporation appearance surface and the metal evaporation surface have substantially the same red metal gloss appearance, a substantially uniform appearance is provided and a sense of depth is hardly obtained.

When the viewing angle is gradually changed, the black at the rear of the film is gradually reflected to the metal evaporation surface observed from the light transmitting portion. When the viewing angle becomes approximately 18 ° as shown in Fig. 10B, the light transmitting portion of the decorative film 10 appears to be substantially black, and the contrast between the light transmitting portion and the film surface becomes most remarkable. The distance difference at this time is approximately 12.6 mm by calculation.

As the viewing angle is further increased, the black area gradually decreases, and at an observation angle of approximately 34 ° in Fig. 10C, the appearance becomes similar to that of the observation from the front.

From the above observations, it is clear in this example that a very novel high quality appearance of significant three dimensions was obtained by a series of modifications of the appearance.

Example 17

A decorative film having a layer configuration as described in Table 3 was produced. This decorative film is designed to be attached to the outside of the lamp cover.

Lamp cover Transparent layer (polyurethane) 30 μm thick Colorless and transparent Base layer (polyester film) 50 μm thick Colorless and transparent Metallic Coating (Aluminum Evaporation Film) 0.5 μm thick Plating tint Bonding layer (polyurethane) 20 μm thick Colorless and transparent Colored layer (polyurethane film) 10 μm thick black Adhesive layer (acrylic adhesive) 40 μm thick Colorless and transparent

Colored layers, base layers and adhesive layers have been produced by using products that are tried and applied outdoors in the field of vehicle exterior features.

The laminated film obtained was cut into a few pieces having a width of 4 mm, these pieces were arranged at 4 mm intervals, and in this state these pieces were integrated by a carrier tape having an adhesive. A decorative film of the same shape as a stripe was obtained.

The decorative film described above was attached to a rear combination lamp of a commercial car, the inner side of which had a plating tint by evaporation of aluminum, its front and rear had a smooth cover, and the inside thereof could be observed. In this example, the decorative cover is compressed and fixed to the area of the inner side of the colorless lamp cover of the reverse lamp (thickness of the lamp cover: about 2 mm, distance from the inner side of the lamp compartment to the receiving surface: about 6 mm) The area is limited to the light non-emitting area around the light emitting portion. The appearance of the obtained lamp structure was observed when the lamp was not turned on while varying the viewing angle vertically in the longitudinal direction of the stripe, and the following results described with reference to Figs. 11A, 11B and 11C were obtained.

When the lamp is observed from its front side as shown in Fig. 11A (viewing angle: 0 °), the metal evaporated exterior surface of the decorative film 10 can be observed through the colorless lamp cover 2, and the housing ( The metal evaporation surface of 1) can be observed through the light transmitting portion. However, since both the metal evaporation appearance surface and the metal evaporation surface have substantially the same colorless metallic gloss appearance, a substantially uniform appearance is provided and a sense of depth is hardly obtained.

When the viewing angle is gradually changed, the black at the rear of the film is gradually reflected to the metal evaporation surface observed from the light transmitting portion. When the viewing angle becomes approximately 14 degrees as shown in Fig. 11B, the light transmitting portion of the decorative film 10 appears to be substantially black, and the contrast between the light transmitting portion and the film surface becomes most remarkable. The distance difference at this time is approximately 16.5 mm by calculation.

As the viewing angle is further increased, the black area gradually decreases, and at an observation angle of approximately 27 ° in Fig. 11C, the appearance becomes similar to the case of the observation from the front.

From the above observations, it is clear in this example that a very novel high quality appearance of significant three dimensions was obtained by a series of modifications of the appearance.

Example 18

A decorative film having a layer structure as described in Table 4 was produced. This decorative film is designed to be attached to the outside of the vehicle as a decorative product.

Transparent layer Polyurethane, 30 μm thick Colorless and transparent Base Polyester, 50 μm thick Colorless and transparent Metal coating Aluminum evaporation film, 0.5㎛ thickness Plating tint Bonding layer Polyurethane, 20 μm thick Colorless and transparent Colored layer Polyurethane film, 10 μm thick blue Adhesive layer Acrylic adhesive, 40 μm thick Colorless and transparent

Colored layers and transparent layers were made by using polyurethane products that were tried and applied outdoors in the field of vehicle exterior features, and colored layers were made by using acrylic adhesives that were tried and applied outdoors.

The laminated film obtained was cut into a few pieces having a width of 2 mm, these pieces were arranged at 2 mm intervals, and in this state these pieces were integrated by a carrier tape having an adhesive. A decorative film of the same shape as a stripe was obtained.

A thin, flat polyester sheet (0.05 mm thick) was prepared having an adhesive layer with an aluminum evaporation film on one side and a release paper on the other side, and a substantially elliptical base material having a size of approximately 12 cm × 4 cm was used for the polyester sheet. Prepared by punching. Next, a mixture of the same amount of transparent urethane resin (3M SV-8008-M10) PART A and PART B was mixed with the base material according to the method described in Japanese Unexamined Patent Publication (Koikai) No. 10-250299. It was injected into the aluminum evaporation film side. When an insufficiently cured and flowable urethane resin mixture was injected, it flowed to the periphery of the base material, and the reaction proceeded over time and cured as polyurethane. A transparent resin layer was obtained having a total thickness of approximately 2 mm and gradually decreasing in thickness from a position spaced approximately 3 mm from the circumference to the circumference.

The transparent resin layer was laminated on the surface of the base material, and the aforementioned decorative film was attached to the surface of the resin layer and compressed. A decorative film shaped like a stripe was produced on the surface, and an emblem was obtained which could be observed through the stripes back. The appearance of the obtained emblem was observed while varying the viewing angle vertically in the longitudinal direction of the stripe, and the results as described below were obtained.

As in Example 17 described above, blue color behind the decorative film is observed at a position farther from the surface of the film from the gap (light transmitting portion) of the decorative film depending on the viewing angle. Thus, the blue color behind the decorative film is reflected by the aluminum evaporation film of the underlying layer and emitted outward through the gap of the decorative film. As a result, an appearance can be obtained that provides a significant sense of depth. According to the observation angle, the blue color of the rear of the decorative film is not observed, and the whole appearance is seen in the plating tint (due to the aluminum evaporation film). As described above, since the blue appearance and the plating tint appearance change continuously with the change of the angle of the viewpoint, a remarkable three-dimensional effect is obtained.

In this example, the technique described in Example 18 above was repeated, but the layer configuration of the decorative film was changed as described in Table 5.

Transparent layer Polyurethane, 30 μm thick Colorless and transparent Colored layer Polyurethane, 10 μm thick blue Base Soft OVC Film, 50 ㎛ Thickness Colorless and transparent Adhesive layer Acrylic adhesive, 40 μm thick Colorless and transparent

Colored layers and transparent layers were prepared by using polyurethane products that were tried and applied outdoors in the field of vehicle exterior features, and the colored layers were further colored with blue dyes. Furthermore, the adhesive layer was made by using an acrylic adhesive which was tried and applied outdoors.

Furthermore, at some viewing angles, the appearance provided by the outer situation is not substantially observed, and the overall appearance is substantially integrated in blue by the blue of the surface of the film and the blue of the back of the film. As described above, since various appearances change continuously with the change of angle of the viewpoint, a remarkable three-dimensional effect is obtained.

Example 20

In this example, the technique described in Example 18 above was repeated, but the layer configuration of the decorative film was changed as described in Table 6.

Transparent layers have been produced by using polyurethane products that are tried and applied outdoors in the field of vehicle exterior features. Furthermore, the adhesive layer was made by using an acrylic adhesive which was tried and applied outdoors.

The appearance of the obtained emblem was observed while varying the viewing angle vertically in the longitudinal direction of the stripe, and the results as described below were obtained.

Depending on the viewing angle, the appearance provided by the shading of the decorative film and the external situation reflected by the aluminum evaporation film is observed from the gap (light transmitting portion) of the decorative film. Furthermore, at some viewing angles, no shadowing of the film is observed and the overall appearance appears to be a flat plated tint that reflects the outside situation. As described above, since various appearances change continuously with the change of angle of the viewpoint, a remarkable three-dimensional effect is obtained.

Example 22

In this example, the technique described in Example 18 above was repeated, but the layer composition of the decorative film was not changed, but the transparent resin layer had a 4 cm × 2 cm character design (3M) of red polyurethane ink (FL500 of Sumitomo 3M).

Furthermore, at some viewing angles, the back of the film is not observed and the overall appearance is seen in a plated tint including the letter design 3M, which is shown one by one. As described above, since various appearances change continuously with the change of angle of the viewpoint, a remarkable three-dimensional effect is obtained.

C.L .: Colored layer

Base layers, colored layers and transparent layers have been produced by using products that are tried and applied outdoors in the field of vehicle exterior features. Furthermore, the adhesive layer was made by using a thermosensitive polyurethane adhesive which was tried and applied outdoors.

Polka dot patterns (red and blue, dot diameter: 2 mm) (inversion of the pattern shown in Fig. 8B) were printed one by one on the base layer to form a colored layer including two layers. The gap between two adjacent dots was 2 mm. The transparent layer was then screen printed to cover the entire colored layer.

As in Example 18, the decorative film was mounted on the surface of the polyurethane transparent resin layer and compressed while heating by supplying hot air from the top for 3 minutes. The decorative film whose flexibility was increased by heating covered the surface of the transparent resin layer and adhered firmly to the extent that it could not be ruptured by the thermosensitive polyurethane adhesive. The initial temperature of the resin surface and the decorative film in the bonding step was greater than 80 ° C.

Depending on the viewing angle, the red appearance provided by the red of the rear of the decorative film reflected by the aluminum evaporation film and the blue appearance provided by the surface of the film are constant from the color contrast and the gap (light transmission) of the decorative film.
