Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative structure, and more particularly, to a decorative structure having a three-dimensional effect and capable of providing an eye-catching appearance, such as a lamp or a decorative tool. The present invention also relates to decorative films useful in making such decorative structures.

2. Description of the Related Art Various vehicles, including passenger cars and trucks, are equipped with a red stop lamp and / or a tail lamp (brake light, tail light) and a direction indicator switch which are lit in association with the use of a brake. Amber-colored turn signal lamps (direction indicator lights) that light up in conjunction with use, colorless backup lamps (reverse light) that light up in conjunction with reverse operation, etc. are installed. Also,
Each vehicle lamp usually has a housing provided with a light emitting opening on the front surface, a plate-shaped or lens-shaped lamp cover that covers the light emitting opening, and a lamp defined by the housing and the lamp cover. And a lamp (light source) arranged in the room (light room). The inner wall of the housing is provided with a reflective layer integral with it or is otherwise provided with a separate reflector. In such a vehicle lamp, when the light source is turned on, the direct light from the light source and the reflected light after being reflected by the inner wall of the housing are emitted to the outside of the lamp via the lamp cover. The lighting function of the period is demonstrated.

In recent years, in such a vehicle lamp,
Not only the lighting function when turned on, but also the improvement of the appearance when turned off during the daytime is required. As one method for satisfying such a user's demand, a non-light emitting portion of the lamp cover is provided with a reflecting surface having the same plating tone as the reflector arranged in the lamp chamber, and the appearance of the lamp through the lamp cover is It is generally done to be bright and transparent. Further, it has been widely practiced to attach an accessory having the same appearance as such a lamp but having no light source to the lamp.

Further, as to the appearance of the decorative portion formed by incorporating the reflecting surface into the lamp cover as described above, a device has been devised that seeks higher designability and differentiation from others.
Generally, in many cases, a concavo-convex pattern is provided on the reflecting surface of the housing or the lamp cover to aim for a peculiar design property based on complicated light reflection. However, only by giving the uneven pattern,
The resulting change in appearance is limited.

Therefore, in Japanese Patent Laid-Open Nos. 11-66906 and 11-66907, a decorative pattern is formed by a combination of vapor deposition, colored printing and convex printing, and the decorative pattern and the reflective surface of the housing cooperate. It has been proposed to further improve the appearance (due to the change in the appearance due to the movement of the line of sight) by the action. Figure 1
1 is an embodiment of a vehicular lamp disclosed in Japanese Patent Laid-Open No. 11-66907. In this lamp, a front lens 52 is attached to cover an opening of a lamp housing 51, and a light source (bulb) 54 is attached to a socket 53. The front lens 52 includes a light emitting portion L and lens dummy portions D and D '. Further, a reflector 55 for reflecting the light from the light source 54 is arranged on the inner wall of the lamp housing 51. In this lamp, the front lens 5
The printing sheet 56 is arranged inside the sheet along the line 2. In the print sheet 56, a colored transparent print film having a predetermined pattern is printed on the inner surface of the transparent plate, and a vapor deposition film is formed on the outer surface of the plate so as to face the print film, and A convex transparent printing layer is formed on the outer surface of the vapor deposition film.

[0006] In the vehicle lamp shown in the figure, the colored light having a brilliant feeling is seen and hidden by the movement of the line of sight from the gaps in the pattern of the vapor deposition film, but it is necessary to realize a three-dimensional effect that can further improve the design. I haven't arrived. Moreover, since the structure of the printing sheet is complicated, the manufacturing process becomes complicated, and the manufacturing cost is inevitably increased. For example, in the step of forming a vapor deposition film in a pattern on a resin plate, not only a masking material having the same pattern as the printing film is required, but also a convex printing layer having the same pattern is overlaid on the vapor deposition film. Since it has to be matched, it is not feasible as an actual process. Furthermore, since the printing sheet must be placed inside the front lens separately from the front lens, it interferes with the emission of light from a light source that needs to pass through the front lens well, and is more difficult than the front lens. Since the printed sheet is arranged closer to the reflector, the stereoscopic effect obtained due to the distance between the two is small. Furthermore, when the plate of the printing sheet has a three-dimensional curved surface, pattern deposition or pattern printing on the surface thereof is infinitely impractical.

In the decorative structure 20 of the present invention, as shown in FIG. 2, one space (air) is formed between the mirror-like appearance surface 1a of the base member 1 and the decorative film 10 without any intervention. It may be configured. Such a configuration is useful, for example, in a lamp structure or the like. Such a decorative structure is particularly suitable as a vehicle lamp structure or a lamp structure in other technical fields.

The lamp structure is preferably a light source, a housing capable of reflecting light from the light source on a mirror-like outer surface of an inner wall, a light emitting opening, and a light transmitting material covering the light emitting opening. And a lamp cover made of resin. In such a lamp structure, the decorative film is attached to the lamp cover.

Furthermore, it is preferable that the decorative film is attached to a non-luminous region of the lamp cover, which does not substantially contribute to the emission of light from the light source. The non-light emitting area of the lamp cover is preferably a peripheral area of the light emitting opening.

Furthermore, it is preferable that the decorative film further has an adhesive layer made of an acrylic adhesive. Further, when the decorative film is used by being attached to the outer surface of the cover film, it is preferable that the decorative film further has a clear layer as the outermost layer.

Otherwise, in the decorative structure 20 of the present invention, as shown in FIG.
An intermediate member 5 made of a light transmissive material may be interposed between a and the decorative film 10. Such a configuration is useful in, for example, an accessory. Appropriate ornaments include, for example, vehicle ornaments such as finishers, garnishes, emblems, malls, emblems such as home appliances, malls such as building materials, ornaments for toys and daily necessities, buildings and displays, etc. There are accessories such as glass plates and resin panels, and others.

In the decorative structure 20 in the form of an accessory, a light-transmissive material suitable for forming the intermediate member 5 is
A resin material, a glass material or a composite thereof is preferable. Moreover, in the accessory 20 of the present invention, the intermediate member 5 may also serve as the base member 1. That is, instead of providing the mirror-like appearance surface 1a to the base member 1, this may be provided to one surface of the intermediate member 5 and the base member 1 may be omitted. FIG. 4 schematically shows such a configuration.

In such an accessory, the decorative film is a metallic film having a metallic appearance similar to or similar to the mirror-like appearance surface of the base member or a colored layer having an arbitrary color tone, like the above-mentioned lamp structure. It is preferable to include at least.

Subsequently, the decorative structure according to the present invention is
In particular, the vehicle lamp structure and the vehicle accessory will be further described as examples. Needless to say, the present invention is not limited to these aspects.

Although the lamp structure according to the present invention can be used in various fields, it is particularly useful as a vehicle lamp structure. The lamp structure can be used in various fields as lighting means, sign means, signal means, and the like. The lamp structure usually includes a light source, a housing capable of reflecting light from the light source on its inner wall, a light emitting opening, and a lamp cover made of a light-transmissive resin that covers the light emitting opening. Examples of such lamp structures include, but are not limited to, those listed below, headlamps, fog lamps,
Clearance lamp, stop lamp, tail lamp,
Includes turn signal lamps and backup lamps. The lamp structure may take the form of a combination lamp in which a plurality of lamps are combined, and for example, it can be used as a rear combination lamp around the rear of the vehicle or as a front combination lamp around the front. In addition, in the present invention, it is usually used in combination with such a lamp structure or independently in order to improve design, etc. Included in the range of accessories. The type of vehicle to which the ramp structure is attached is not particularly limited, and includes passenger cars (including RV cars, campers, etc.), buses, trucks, and the like. It is particularly suitable for passenger cars because it can improve design and visibility.

FIG. 5 shows a general structure of the lamp structure according to the present invention. The lamp structure 30 includes a lamp housing 1 and one lamp chamber (lamp chamber) defined by a lamp cover 2 attached to cover a light emitting opening (light emitting region) L on the front surface thereof. The lamp chamber may be composed of two or more chambers, if necessary. The respective lamp chambers may be independent of each other or may be in communication with each other. In the lamp chamber, a light source 4 having an appropriate brightness is usually arranged by being fitted in a socket (not shown) or the like. In some cases, the light source may be removed from some lamp chambers. The inner wall 1a of the housing 1 has a reflective film structure such as a concave mirror so that the light from the light source 4 is condensed, and has a mirror-like appearance surface. Although not shown, a concave mirror or a similar light reflecting means (usually a reflector) may be provided instead of the inner wall having such a mirror-like appearance surface. Further, the light source 4 may have a cap colored in a predetermined color, if necessary. This is because when a colored cap is used, a colorless cover can be used as the lamp cover instead of the colored cover. For example, the turn signal lamp can be covered with an amber colored cap. In addition, as a recent tendency, the lamp cover 2 has a light source 4 for improving the design.
A light non-transmissive region that does not substantially participate in the emission of light from the, i.e., a non-light emitting region is provided, but the present invention is not an exception, and the non-light emitting region S is provided as illustrated. . Further, in the non-light emitting area S, the multi-layered decorative film 10 according to the present invention is attached. The decorative film 10 is attached to the inside of the lamp cover 2 in the illustrated example, but in the case of the present invention, it can be attached to the outside as described below.

The lamp structure of the present invention needs to have a mirror-like appearance surface on the inner wall of its housing. The mirror-like appearance surface means that the surface is a reflecting surface capable of substantially projecting an opposing object, like a mirror, and its reflecting ability can be arbitrarily changed. That is, the mirror-like appearance surface does not necessarily need to be a smooth surface like an actual mirror, and may be a reflecting surface that reflects a certain degree of shape and can be seen as a shade with color. The mirror-like appearance surface can be formed by various techniques, but usually it should be formed on the inner wall of the housing by metal deposition, metal plating, coating with paint containing metal powder, sticking of plating appearance transfer foil or film, etc. Alternatively, the mirror-like appearance surface may be formed by installing a thin metal plate, a metal appearance sheet / film, or a plate to which the film is attached in the space on the inner wall side of the housing.

Further, in the lamp structure of the present invention, the light emitting opening (the light emitting region and the non-light emitting region adjacent thereto) of the lamp chamber is covered with the lamp cover. The lamp cover is preferably molded from a light-transmissive resin by an injection molding method or another molding method. The lamp cover is not particularly limited as long as it has a shape and a size that at least covers the light emitting surface of the lamp chamber, but is generally circular, rectangular, or square, and in some cases, elliptical. It may have a deformed shape such as an L shape.

The lamp cover may be colorless or, if desired, that is to say colored depending on the hue of the light emitted from it. Further, if the lamp chambers are a combination of two or more chambers, each lamp chamber may be colored with a different hue. For example, the cover of a stop lamp / tail lamp that requires red light emission is colored red, and the cover of a turn signal lamp that requires amber light emission is colored amber. Alternatively, instead of coloring the cover, a colorless cover may be used to cover the lamp with a colored cap. By using such an alternative method, it is possible to obtain an appearance different from that using the colored cover. Of course, the cover of the colorless backup lamp need not be colored.

The colorless or colored lamp cover is
It can be advantageously formed by molding from any light transmissive resin. Suitable molding methods include conventional molding methods such as injection molding and vacuum molding. The raw material resin used for molding is not limited to those listed below, but examples thereof include a styrene resin, a hard vinyl chloride resin, an acrylic resin, and a polycarbonate resin. In particular, acrylic resin can be advantageously used. This is because it has excellent strength and transparency and can be advantageously subjected to coloring. Depending on the case, a glass plate or the like may be used for the lamp cover.

Further, when manufacturing a colored lamp cover, an appropriate amount of a coloring agent can be mixed in the resin raw material as described above. Suitable colorants include, but are not limited to, those listed below, pigments such as perylene pigments, azo pigments, iron oxides, or quinophthalone dyes, azo dyes, disazo dyes, anthraquinone dyes, benzopyran dyes, etc. Dyes (all from the color index) can be mentioned. In the practice of the present invention, dyes such as azo dyes and disazo dyes can be particularly advantageously used because they are excellent in dispersibility in a resin and have good color developability, transparency and weather resistance.

In the manufacture of the lamp cover, the resin raw material may be mixed with additives commonly used in the field of plastic molding, in addition to the colorant. Examples of suitable additives include ultraviolet absorbers, light stabilizers, and heat stabilizers. For example, suitable UV absorbers include, but are not limited to, those listed below, including benzotriazoles, benzophenones, diphenyl acrylates, amine UV absorbers, and the like. Further, the addition amount of such an ultraviolet absorber can be changed in a wide range, but is usually in the range of about 0 to 3% by weight based on the total amount of the raw material resin.

The lamp cover is usually flat and has a smooth surface, but the inner surface (surface on the light source side) may have an uneven pattern. This is because the concavo-convex pattern provides a function as a lens body or a retroreflective function. The concavo-convex pattern can be transferred from the mold to the molded body (lamp cover) at the molding stage, for example, by imparting the pattern to the mold. Further, a lamp cover having a three-dimensional curved surface or the like may be used in order to improve design and the like. Although the thickness of the lamp cover is not particularly limited, it is usually about several mm.

The lamp cover is provided with a decorative film in its non-light emitting area, that is, in the light non-transmissive area where the light emitted from the light source arranged in the lamp chamber is not transmitted or does not need to transmit such light. Attached. here,
Although various regions can be considered as the non-luminous region of the lamp cover, it is usually the peripheral region of the light emitting opening of the lamp chamber. That is, the non-light emitting area is a headlamp,
Areas around turn signal lamps, backup lamps, etc. These non-luminous regions can usually have any shape in accordance with the peripheral region of the light emitting opening.

In the lamp cover, a specific decorative film, which will be described in detail below, is attached to a portion of the lamp cover that does not adversely affect the progress of the light from the light source, whereby requirements such as vehicle operation rules are met. While satisfying
It is possible to realize remarkable improvements in appearance and design. In particular, according to the present invention, it is possible to obtain a new and eye-catching design appearance with a very three-dimensional effect. As will be understood from the following description, the three-dimensional effect is largely due to the uniformity of the portion that can be seen from the pattern (light-shielding portion) of the decorative film and the gap (light-transmitting portion) between them.

The decorative film of the present invention has (1) a pattern derived from the combination of the light-transmitting portion and the light-shielding portion,
And (2) at least one appearance modulation layer comprising a metallic coating having the same or similar metallic appearance as that of the inner wall of the housing of the lamp structure, preferably a metallic luster appearance, a colored layer having an arbitrary color tone, or a combination thereof. It is a decorative film having a multilayer structure including. The decorative film can have additional layers such as a bonding layer, a support layer, a base layer, an adhesive layer, and a clear layer, if necessary.

The appearance-modulating layer may be used alone or 2
You may use combining a layer or more. When two or more layers are used in combination, the arrangement of the appearance modulation layer can be arbitrarily changed. To further describe the layer structure of the decorative film, when it is attached to the inner surface of the lamp cover, it is preferable to attach the decorative film so that the metallic coating is closer to the lamp cover than the colored layer.

FIG. 6 is a sectional view showing an example in which a decorative film having the above-mentioned layer structure is attached to the inner surface of the lamp cover (the pattern is omitted for simplification of description). The illustrated decorative film 10 is used for the lamp cover 2
From the side of the adhesive layer 14, the first intermediate layer 11, the first
Appearance modulation layer (metallic coating) 15, second intermediate layer 1
2, a second appearance modulation layer (coloring layer) 16, and a third intermediate layer 13. Here, the first and second appearance-modulating layers 15 and 16 may replace the metallic coating and the coloring layer, may be composed of only two coloring layers, and may further include the metallic coating or the coloring layer. You may comprise only a single layer. In addition, the first, second and third intermediate layers 11, 1
2 and 13 are optional and can function as a bonding layer, a support layer, a base layer, and the like, respectively. These intermediate layers may be used as a single layer or as a laminate of two or more layers. In principle, the first and third intermediate layers 11 and 13 are colorless and transparent, and at least should not adversely affect the designability derived from the metallic coating 15 and the colored layer 16.

It is also preferable that the decorative film is used by being attached to the outer surface of the lamp cover. In such a case, it is preferable to attach a decorative film to the outer surface of the lamp cover such that the metallic coating is located farther from the lamp cover than the colored layer.

FIG. 7 is a sectional view showing an example in which a decorative film having the above-mentioned layer structure is attached to the outer surface of the lamp cover (the pattern is omitted for simplification of description). The illustrated decorative film 10 is used for the lamp cover 2
From the side of the adhesive layer 14, the first intermediate layer 11, the second
Appearance modulation layer (coloring layer) 16, second intermediate layer 12, first
Appearance modulation layer (metallic coating) 15, third intermediate layer 1
3 and a clear layer (surface layer) 17. The second appearance modulation layer (colored layer) 16 may also serve as the first intermediate layer 11. Here, the first and second appearance modulation layers 15 and 1
6 may replace the metallic coating and the colored layer, may be composed of only two colored layers, and may be composed of only a single layer of the metallic coating or the colored layer. Further, the first, second and third intermediate layers 11, 12 and 13 are optional and can function as a bonding layer, a support layer, a base layer and the like, respectively. These intermediate layers may be used as a single layer or as a laminate of two or more layers. In addition, the first and third intermediate layers 11 and 13
Is in principle colorless and transparent, and at least should not adversely affect the designability derived from the metallic coating 15 and the colored layer 16.

The decorative film has a combination of a light-transmitting portion and a light-shielding portion, and therefore can have an arbitrary pattern derived from the combination thereof. Suitable patterns include, but are not limited to, those listed below, including stripes, round holes, dots, triangular holes, square holes, lattice holes, checkerboard patterns, and the like. As one deformation of the stripe, a pattern in which thin lines are sparsely distributed is also effective. If necessary, these patterns may be combined and applied to the decorative pattern. These patterns may form a light-transmitting portion, or may form a light-shielding portion. The size of each pattern can be arbitrarily changed depending on the design effect desired to be exhibited.

FIG. 8 is a plan view showing an example of the pattern of the decorative film. The decorative film 10 of FIG.
In this example, the stripe-shaped light-shielding portion 10A and the stripe-shaped light-transmitting portion 10B are repeated at the same pitch p to form a stripe-shaped pattern. Further, the decorative film 10 of FIG. 8B is an example in which the light-shielding portions 10A of solid are repeatedly formed with the light-transmitting portions 10B in the shape of round holes at the same pitch p to form a perforated pattern. Further, the decorative film 10 in FIG. 8C is an example in which a square light-shielding portion 10A and a square light-transmitting portion 10B having the same size are repeated at the same pitch p to form a checkered pattern.

In the decorative film of the present invention, (1) its aperture ratio (the ratio of the light-transmitting part to the entire decorative film) is 1
0 to 99%, and (2) the ratio d between the decorative film and the inner wall of the housing (see FIG. 2) and the pitch p (see FIG. 8) between the light-transmitting portion and the light-shielding portion of the decorative film. Is preferably at least 1/40, more preferably the aperture ratio is in the range of 20 to 97%, and the ratio of the spacing d and the pitch p is 1/20 or more, and particularly preferably, the aperture ratio is 35. ˜90%, and the ratio of the spacing d to the pitch p is ⅓ to 5/1. When the opening ratio of the decorative film is less than 10%, the three-dimensional effect obtained is poor, and when it exceeds 99%, the desired effect can no longer be obtained. Further, even if the ratio of the interval d and the pitch p is less than 1/40, the obtained stereoscopic effect becomes poor.

In the decorative film of the present invention, the metallic film as the appearance-modulating layer is a reflective film on the inner wall of the housing forming the lamp chamber or, if any, a reflective film such as a reflector attached to the inside of the housing. It is formed to have the same or similar appearance, usually a metallic appearance, especially a metallic luster appearance. The metallic coating can be formed according to various techniques. The metallic coating may be formed, for example, by vapor deposition or sputtering of a metal material such as aluminum, chromium, or tin. Otherwise, a coating of resin or the like in which metal powder such as aluminum powder is dispersed, glitter ink or glitter. It may be formed by printing or coating (including electrostatic coating) of a coating material in which the agent is dispersed, such as pearl mica coating material. Further, the metallic coating may be formed by coating, extruding or sticking a film or sheet having a desired light-reflecting appearance. It is preferable that the film-forming material used here has not only the desired light-reflecting appearance but also excellent weather resistance which is a requirement for the lamp cover. The thickness of the metallic coating can be widely changed depending on the desired design effect and the like, but is usually in the range of about 5 to 500 μm, and more preferably in the range of about 20 to 100 μm.

The colored layer used in combination with the metallic coating or independently can also be formed by using various conventional thin film forming techniques similarly to the metallic coating. That is, the colored layer may be formed by printing ink or paint having a predetermined color tone, painting (including electrostatic coating), or coating a film or sheet having a predetermined color tone, extruding the resin, Alternatively, it may be formed by pasting. The ink or paint may contain a glittering material such as pearl powder or metal powder, and other additives. The colored layer forming material used here preferably has not only colorability but also excellent weather resistance which is a requirement for the lamp cover. Further, according to the knowledge of the present inventor, it is effective that the colored layer is formed so as to have a darker color tone because the contrast becomes remarkable. The thickness of the colored layer can be widely changed depending on the desired design effect and the like, but is usually in the range of about 5 to 500 μm, and more preferably in the range of about 20 to 100 μm.

More specifically, according to one embodiment, the colored layer is, for example, a polyester film, a polyethylene film, a polycarbonate film, a vinyl chloride film, an acrylic film, a polyurethane film, a polyolefin film or a vinylidene fluoride film. It can be formed from a plastic material in the form of a colored film. The colored film useful as a light-shielding part is
It can be formed by coloring a transparent film with an arbitrary colorant such as a pigment or a brightening agent. Examples of suitable pigments include achromatic pigments such as titanium oxide and carbon black, and inorganic and organic chromatic pigments. Examples of the brightening agent include aluminum flakes and pearl powder.

Further, the metallic coating and the coloring layer may additionally have a pattern, a picture, a character, etc., if necessary. This is because the design of the decorative film is further improved.

In the decorative film of the present invention, it is preferable to interpose the intermediate layer between the colored layer and the metallic coating or at any other arbitrary position in order to give it a rigidity and enhance the bonding strength. The intermediate layer can function as, for example, a bonding layer, a support layer, a base layer, or the like. Suitable intermediate layers are, for example, a joining layer made of polyurethane resin or the like, or a base layer made of polyester resin. These intermediate layers may be used as a single layer or as a laminate of two or more layers.

Since the decorative film of the present invention is used by attaching it to a lamp cover, it generally has an adhesive layer. The adhesive layer used here can be formed using an adhesive that is commonly used in the field of adhesive tapes, pressure-sensitive adhesive tapes, and the like, for example, pressure-sensitive type, heat-sensitive type, and photocurable type adhesives. Examples of suitable adhesives include acrylic adhesives, polyurethane adhesives, polyester adhesives, and the like.
In consideration of weather resistance and the like, an acrylic adhesive can be particularly advantageously used. Although the thickness of such an adhesive layer can be varied over a wide range, it is usually in the range of about 10 to 500 μm, and more preferably in the range of about 20 to 100 μm. When the thickness of the adhesive layer is less than 10 μm, a satisfactory adhesive force cannot be obtained, and when it exceeds 500 μm, the total thickness of the decorative film becomes very large, which is not preferable. In fact, when it is attached to the outer surface of the lamp cover, it will be in a state of protruding from the cover, which will give a strange feeling. A release liner is preferably attached to such an adhesive layer to facilitate handling and attachment of the lamp cover.

When the decorative film of the present invention is used by being attached to the outer surface of the cover film, it is preferable that the decorative film further has a clear layer as the outermost layer. From the viewpoint of causing the clear layer to act as a protective film, it is desirable that the clear layer has weather resistance and heat resistance in addition to transparency, which is an essential property. It is also desirable that the clear layer has good adhesion to the underlying layer. Suitable resins for forming the clear layer are not limited to those listed below, but include polyester resins, polyethylene resins, polycarbonate resins, vinyl chloride resins, acrylic resins, polyurethane resins, polyolefin resins,
Fluorine-based resins (PVdF, ETFE, etc.) can be used. If necessary, these resins may be used as a mixture or a copolymer. Furthermore, the clear layer can also impart gloss to the surface of the lamp cover and improve the appearance.

In order to enhance the weather resistance of the decorative film, it is preferable to mix an ultraviolet absorber in the clear layer. Suitable UV absorbers include, but are not limited to, those listed below, including benzotriazole UV absorbers, benzophenone UV absorbers, cyanoacrylate UV absorbers, and the like.

Further, the thickness of the clear layer can be widely changed depending on the desired effect, etc., but is usually in the range of about 1 to 500 μm, and more preferably in the range of about 10 to 100 μm. is there. If the thickness of the clear layer is less than 1 μm, the effect as a protective film cannot be obtained, and if it exceeds 500 μm, the entire thickness of the decorative film becomes very large, which is not preferable.

The light shielding portion of the appearance modulation layer may be formed of a light shielding material. For example, after preparing a sheet- or film-shaped material having a light-shielding property as a whole, light-transmitting portions such as stripes, lattices, and dots may be opened in the material by punching or the like. You may put a slit in various materials. Further, at the stage of forming the film-like appearance modulation layer, a colorant may be mixed into the film raw material to manufacture the appearance modulation layer in which the light shielding portion is formed in a predetermined pattern. Further, the light-shielding portion may be formed by a method such as sticking a colored film having a predetermined pattern on the transparent film or printing a colored layer so as to have a predetermined pattern. The obtained decorative film can be attached to the surface of the lamp cover by pressure bonding, heat lamination or the like, if necessary, using a carrier tape or the like. According to the present invention, it is not necessary to form a decorative pattern through a complicated work such as vapor deposition and printing, so that the workability is good and the effectiveness is very large.

The decorative structure according to the present invention includes not only the above-mentioned lamp structure but also other lamp structures (having no light source in the lamp chamber) and other decorative structures. Other decorative structures include, for example, vehicles,
Examples thereof include home electric appliances, toys, and accessories used for pasting. For example, vehicle accessories include, but are not limited to those listed below, finishers, garnishes, emblems, malls, and the like.

The illustrated vehicle accessory 40 is an example of an emblem and includes a base material 41, a decorative film 10, and a transparent intermediate member 45 sandwiched by the base material 41 and the decorative film 10. On the mirror-like outer surface 41a of the base material 41, a car name logo 46 is pattern-printed. The accessory 40 is attached to a predetermined portion of the vehicle 47 by the adhesive layer 48.

The decorative film 10 comprises an adhesive layer 14, a first intermediate layer 11, a second appearance-modulating layer (coloring layer) 16, a second intermediate layer 12, and a first intermediate layer 12 in this order from the base material 41 side. It consists of an appearance modulation layer (metallic coating) 15, a third intermediate layer 13, and a clear layer (surface layer) 17. Here, the first and second appearance-modulating layers 15 and 16 may replace the metallic coating and the coloring layer, may be composed of only two coloring layers, and may further include the metallic coating or the coloring layer. You may comprise only a single layer. Further, the first, second and third intermediate layers 11, 12 and 13 are optional, respectively,
It can function as a bonding layer, a support layer, a base layer, and the like. These intermediate layers may be used as a single layer or as a laminate of two or more layers. Furthermore, the first and third
In principle, the intermediate layers 11 and 13 are colorless and transparent, and at least should not adversely affect the designability derived from the metallic coating 15 and the colored layer 16.

In the illustrated vehicle accessory, the base material is not particularly limited, and can be arbitrarily selected according to the type of the accessory. Suitable base materials are, for example, films or sheets of various plastic materials such as polyester resin and polyurethane resin, and if necessary, metal foil or metal sheet may be used. In some cases, for example, plastic plates or It may be a metal plate or the like. These base materials may be used as they are,
An adhesive layer may be provided on the side opposite to the decorative film. The base material may be omitted, and the mirror-like appearance surface to be given to the base material may be formed on one surface of the transparent intermediate member described below.

In the accessory of the present invention, it is necessary to provide a mirror-like appearance surface on one surface of the base material or, if necessary, on the transparent intermediate member. The mirror-like appearance surface is basically
It can be similar to that of the lamp structure described above, and thus does not necessarily require a smooth surface such as an actual mirror, and it does not necessarily show a certain shape or show a shade with color. It may be a reflective surface. In addition, the mirror-like appearance surface can be usually formed by metal vapor deposition, metal plating, coating with a metal powder-containing paint, sticking of a plating appearance transfer foil or film, as in the case of the lamp structure. Furthermore, the mirror-like appearance surface may partially have a design such as a pattern, a picture, or a letter in combination therewith.

The transparent intermediate member arranged between the base material (which may be omitted) and the decorative film can be formed of various light transmissive materials. Suitable light-transmissive materials for forming the intermediate member are light-transmissive and moldable materials such as polyester resin, polyurethane resin, polyvinyl chloride resin, acrylic resin, polycarbonate resin, polystyrene resin, melamine resin, Polyolefin resin (polypropylene, polyethylene, EEA, AE
E, EVA, etc., fluorine resin (PVdF, ETFE)
Etc.), and these resin materials may be used alone, or may be a mixture or copolymer of two or more kinds. These resin materials are manufactured by injection molding, hot pressing,
A desired shape and size can be formed by using a casting method, an extrusion molding method, a carving method, or the like. Further, the intermediate member may be made of another material having light transparency, for example, an inorganic material such as glass, instead of the resin material as described above.

The intermediate member is usually colorless and transparent, but it may be colored depending on the intended design effect and the like, and it is particularly preferable that it is lightly colored. Further, as described above, if the base material is not used, a mirror-like appearance surface may be formed on one surface of the base material by the same method as described above.

The thickness of the intermediate member is not particularly limited, but is usually about several mm. However, depending on the type of accessory, the intermediate member may be used with a thickness of 1 mm or less or 10 mm or more.

The decorative film used in combination with the intermediate member can have basically the same constitution as that used in the above-mentioned lamp structure, and therefore the metallic film, the coloring layer or the combination thereof. As an appearance modulation layer.

The metallic coating, which is a member of the appearance-modulating layer, is usually formed so as to have the same or similar appearance as the mirror-appearing surface of the base of the decorative film, usually a metallic appearance, especially a metallic luster appearance. As described above, such a metallic coating can be formed according to various techniques, and may be formed by, for example, vapor deposition or sputtering of a metal material, or a resin in which a metal powder is dispersed. The coating may be formed by printing, painting, or the like, coating of a glittering ink or a paint in which a glittering agent is dispersed. Further, the metallic coating may be formed by coating, extruding or sticking a film or sheet having a desired light-reflecting appearance. The thickness of the metallic coating can be widely changed depending on the desired design effect and the like, and is usually in the range of about 5 to 500 μm, and more preferably in the range of about 20 to 100 μm.

The colored layer used in combination with the metallic coating or independently can also be formed by using various conventional thin film forming techniques, like the metallic coating. That is, the colored layer may be formed by printing or painting an ink or paint having a predetermined color tone, or by forming a film or sheet having a predetermined color tone by coating, resin extrusion, or sticking. May be. The ink or paint may contain a glittering material such as pearl powder or metal powder, and other additives. The thickness of the colored layer can be widely changed depending on the desired design effect and the like, and is usually about 5 to 50.
0 μm, more preferably about 20 to 10
It is in the range of 0 μm.

The metallic coating or colored layer used in the decorative film may additionally have a pattern, a picture, a character or the like, if necessary. This is because the design of the decorative film is further improved.

The decoration film has a waist,
In order to enhance the bonding strength, it is preferable to interpose an intermediate layer between the colored layer and the metallic coating or at any other position. The intermediate layer can function as, for example, a bonding layer, a support layer, a base layer, or the like. Suitable intermediate layers include, for example, a joining layer made of polyurethane resin,
A base layer made of polyester resin. These intermediate layers may be used as a single layer or as a laminate of two or more layers.

Since the decorative film is used by attaching it to the intermediate member, it generally has an adhesive layer. The adhesive layer used here can be formed using an adhesive that is commonly used in the field of adhesive tapes, pressure-sensitive adhesive tapes, and the like, for example, pressure-sensitive type, heat-sensitive type, and photocurable type adhesives. Suitable adhesives include, for example, acrylic adhesives, polyurethane adhesives, polyester adhesives, etc., as described above.
The thickness of the adhesive layer can be varied over a wide range and is usually in the range of about 10 to 500 μm, more preferably in the range of about 20 to 100 μm.

When the decorative film is used by being attached to the intermediate member, it is preferable that the decorative film further has a clear layer as the outermost layer. From the viewpoint of causing the clear layer to act as a protective film, it is desirable that the clear layer has weather resistance and heat resistance in addition to transparency, which is an essential property. It is also desirable that the clear layer has good adhesion to the underlying layer. Suitable resins for forming the clear layer are not limited to those listed below, but include polyester resins, polyethylene resins, polycarbonate resins, vinyl chloride resins, acrylic resins, polyurethane resins, polyolefin resins, and fluorine resins (PVd).
F, ETFE, etc.) and the like. If necessary, these resins may be used as a mixture or a copolymer. The thickness of the clear layer can be widely changed depending on the desired effect, and is usually about 10-5.
The range is 00 μm, more preferably about 20 to 1
It is in the range of 00 μm.

The above-mentioned clear layer may be omitted if not necessary, or instead, a film-like or sheet-like material similar to the intermediate member may be stuck or laminated and used. A novel design effect that cannot be obtained with the clear layer will be obtained.

As described above, the decorative film used in the decorative structure of the present invention is a multi-layered film capable of exhibiting a special appearance due to the pattern formed by perforation or the like. A lamp structure having a housing with a reflecting surface by vapor deposition or a reflector, and a lamp cover, or an accessory having a similar structure, which is attached to a part of the lamp cover or the like. The decorative film has a metallic glossy appearance, such as aluminum vapor deposition, on the side visible from the outside, and a colored appearance on the opposite side, on the contrary.

When the lamp structure and the accessory having such a structure are viewed from the outside, the metallic luster of the decorative film can be observed in the portion where the decorative film is provided. on the other hand,
In the light-shielding portion (the portion where the film is not applied) of the decorative film, the reflective surface such as the housing can be seen through. Also,
If the part without the film is projected on the reflective surface, it is recognized as a metallic glossy surface, while if the part with the film is projected, the color tone of the colored layer is recognized. In this way, the appearance can be highly changed depending on the viewing angle. Further, in the former case, since the metallic appearance of the decorative film and the appearance of the reflecting surface such as the housing are substantially similar to each other, it looks continuous so that the depth difference of the reflecting surface is not felt. On the other hand, in the latter case, since the metallic glossy surface of the decorative film and the colored surface of the colored layer have different appearances, a sense of depth corresponding to the reciprocating distance between the decorative film and the housing is recognized. Therefore, when the observation is performed while continuously changing the angle, it appears that a design surface having a depth twice that of the actual depth appears or disappears, or the area thereof increases or decreases. Therefore, an unprecedentedly high quality and novel appearance can be obtained. The decorative film can be attached to either the inner or outer surface of the lamp cover when it is used in a lamp structure, but if the lamp cover is colored, it is better to stick it to the inner surface. , It will look more uniform at various angles and the design will be enhanced.

[0083]

The present invention will be described below with reference to its embodiments. It should be understood that the present invention is not limited to these examples. Examples 1 to 15 and Comparative Examples 1 to 3 Laminated films having the following layer structures were produced.

Adhesive layer (transparent acrylic pressure-sensitive adhesive, 35 μm
m thickness) / metallic coating (tin vapor deposition layer, 0.5 μm thickness)
/ Base layer (polyurethane film, 50 μm thickness) / Black colored layer (polyurethane film, 5 μm thickness) / Clear layer (transparent polyurethane film, 20 μm thickness) This laminated film has different film widths as described in Table 1 below. After cutting into different pitches, the pitches are different as shown in Table 1 below (periodic value at which the light-transmitting portion and the light-shielding portion are repeated).
In the state of being arranged so as to be p, they were integrated by a carrier tape with an adhesive. The obtained striped decorative film was attached to a colorless transparent acrylic plate (thickness: 2 mm) and pressure-bonded.

An acrylic resin panel having the same shape and size as the above acrylic plate was attached with an aluminum vapor deposition film on one surface to make it a mirror surface state, and then the acrylic resin produced in the previous step so that the aluminum vapor deposition film and the film surface face each other. The plates were placed at intervals d (see Table 1). In Example 15, a glass plate having a thickness of 10 mm was sandwiched between an acrylic plate and an acrylic resin panel instead of forming the gap d.

The depth appearance of the aluminum deposition surface of the acrylic resin panel was observed from the acrylic plate side, and the observation results as shown in Table 1 below were obtained.

[0087]

[Table 1]

In Table 1 above, ◯ indicates that the black color of the back surface of the decorative film was visible on the mirror surface formed by aluminum vapor deposition, there was a sense of depth, and the change due to the movement of the line of sight was very effective.

Δ indicates that the black color on the back surface of the decorative film was visible on the mirror surface formed by aluminum vapor deposition, there was a sense of depth, and a change due to the movement of the line of sight was recognized to some extent.

X indicates that no sense of depth was felt. Example 16 A decorative film having a layer structure as shown in Table 2 below was produced. This decorative film is designed to be attached to the inside of the lamp cover.

[0091]

[Table 2]

Here, for the formation of the coloring layer, the base layer, and the adhesive layer, products having a track record of being used outdoors in the field of automobile exteriors were used.

The obtained laminated film was cut into a width of 4 mm, and then arranged at intervals of 4 mm, and integrated with a carrier tape with an adhesive. A striped decorative film was obtained.

The above-mentioned decorative film was attached to a rear combination lamp of a commercially available passenger car of a type in which the inner surface of the housing was plated with aluminum by vapor deposition and the front and back surfaces were smooth, and the inside of the lamp chamber could be overlooked. In this example, the red lamp cover (thickness: about 2 mm,
A decorative film was pressure-bonded to the inner surface of the inner surface of the lamp cover to the housing surface of the lamp chamber (about 6 mm) only in the non-light emitting area provided around the light emitting portion. When the appearance of the obtained lamp structure was observed while the lamp was not lit and the observation angle was changed perpendicularly to the longitudinal direction of the stripe, the results as described below with reference to FIG. 10 were obtained. Was obtained.

When viewed from the front (observation angle: 0 °) as shown in FIG.
The metal vapor deposition appearance surface of the decorative film 10 and the metal vapor deposition surface of the housing 1 through the transparent portion of the film can be recognized, but since they have almost the same red metal gloss appearance, they look almost uniform and have a sense of depth. I can hardly feel it.

As the observation angle is shifted, a black color on the back surface of the film is seen on the metal vapor-deposited surface of the housing 1 which is gradually seen from the light-transmitting portion of the decorative film 10. As shown in FIG. At 18 °, the transparent portion of the decorative film 10 appears almost black, and the contrast with the film surface becomes most remarkable. The distance difference between the viewpoints at this time is calculated to be about 12.6 mm.

As the observation angle is further increased, the black area gradually decreases, and the observation angle in FIG.
At 4 °, the appearance is similar to that observed from the front.

From the above observation results, it is clear that in this example, a highly three-dimensional and highly novel appearance was obtained by a series of changes in appearance. Example 17 A decorative film having a layer structure as shown in Table 3 below was produced. This decorative film is designed to be attached to the outside of the lamp cover.

[0099]

[Table 3]

Here, for the formation of the coloring layer, the base layer, and the adhesive layer, products having a track record of outdoor use in the field of automobile exteriors were used.

The obtained laminated film was cut into a width of 4 mm, and then aligned at intervals of 4 mm, and integrated with a carrier tape with an adhesive. A striped decorative film was obtained.

The above-mentioned decorative film was attached to a rear combination lamp of a commercial passenger car of a type in which the inner surface of the housing is plated with aluminum by vapor deposition, and the front and back surfaces are provided with smooth lamp covers, and the inside of the lamp chamber can be overlooked. In this example, the colorless lamp cover of the back light unit (thickness: about 2 m
m, the distance from the inner surface of the lamp cover to the housing surface of the lamp chamber: about 6 mm), the decorative film was pressure-bonded to the outer surface around the light emitting portion only in the non-light emitting area. When the appearance of the obtained lamp structure was observed while the lamp was not lit and the observation angle was changed perpendicularly to the longitudinal direction of the stripe, the results as described below with reference to FIG. 11 were obtained. Was obtained.

When viewed from the front (observation angle: 0 °) as shown in FIG.
The metal vapor deposition appearance surface of the decorative film 10 and the metal vapor deposition surface of the housing 1 through the light transmitting portion of the film can be recognized, but since they have almost the same colorless metal gloss appearance, they look almost uniform and have a sense of depth. I can hardly feel it.

As the observation angle is shifted, a black color on the back surface of the film is seen on the metal vapor-deposited surface of the housing 1 which is gradually seen from the light-transmitting portion of the decorative film 10. As shown in FIG. At 14 °, the light-transmitting portion of the decorative film 10 appears almost black, and the contrast with the film surface becomes most remarkable. The distance difference between the viewpoints at this time is calculated to be about 16.5 mm.

As the observation angle is further increased, the black area gradually decreases, and the observation angle in FIG.
At 7 °, the appearance is similar to that observed from the front.

From the above observation results, it is clear that, in this example, a highly three-dimensional and highly novel appearance was obtained due to a series of changes in appearance. Example 18 A decorative film having a layer structure as shown in Table 4 below was produced. This decorative film has a specification such that it is attached to the outer surface of the vehicle as an ornamental emblem via an adhesive layer.

[0107]

[Table 4]

Here, both the colored layer and the clear layer were formed by using a polyurethane-based product which has a proven track record of being used outdoors in the field of automobile exteriors, and the colored layer was further colored with a blue pigment. Furthermore, an acrylic pressure-sensitive adhesive, which has a track record of being used outdoors, was used for forming the adhesive layer.

The obtained laminated film was cut into a width of 2 mm, and then arranged at intervals of 2 mm, and integrated with a carrier tape with an adhesive. A striped decorative film was obtained.

A thin and flat polyester sheet (thickness: 0.05 mm) having an aluminum vapor-deposited film on one surface and an adhesive layer with release paper on the surface opposite to it was prepared and punched out to a thickness of about 12 cm. A base material close to an oval shape of 4 cm was prepared. Then, on the aluminum vapor-deposited film side of the substrate, a transparent urethane resin for VITROTRIM ^™ (manufactured by 3M, SV-8008-M10) according to the method described in JP-A-10-250299: Part A
And an equal volume mixture of Part B was cast. When the urethane resin mixture was cast while it was in an insufficiently cured and fluid state, the mixture was cast to the peripheral portion of the base material, and then the reaction proceeded sufficiently over time to cure it as a polyurethane. A transparent resin layer having a total thickness of about 2 mm and having a thickness that smoothly decreased from about 3 mm from the peripheral edge toward the edge was obtained.

After raising the transparent resin layer on the surface of the substrate,
The above decorative film was attached to the surface and pressure-bonded. The surface was decorated in stripes, and an emblem with a view of the interior was obtained through the gaps between them. The appearance of the obtained emblem was observed while changing the observation angle perpendicular to the longitudinal direction of the stripe, and the following observation results were obtained. [Observation Result] As in the case of Example 17, the blue color on the back surface of the decorative film is seen at a distance from the film surface from the gap (translucent portion) of the decorative film depending on the observation angle.
This is because the blue color on the back surface of the decorative film is reflected by the underlying aluminum vapor deposition film and is emitted to the outside through the gap between the decorative films. As a result, an appearance with a prominent sense of depth is obtained. Further, depending on the observation angle, the blue color on the back surface of the decorative film cannot be seen, and the whole looks like a plating tone (due to the aluminum vapor deposition film). In this way, the blue appearance and the plating-like appearance appear to continuously change according to the change in the angle of the viewpoint, so that the three-dimensional effect becomes outstanding. Example 19 The procedure described in Example 18 was repeated, but in this example, the layer structure of the decorative film was changed as shown in Table 5 below.

[0112]

[Table 5]

Here, both the colored layer and the clear layer were formed by using a polyurethane-based product which has a track record of being used outdoors in the field of automobile exteriors, and the colored layer was further colored with a blue pigment. Furthermore, an acrylic pressure-sensitive adhesive, which has a track record of being used outdoors, was used for forming the adhesive layer.

The appearance of the obtained emblem was observed while changing the observation angle perpendicular to the longitudinal direction of the stripe, and the following observation results were obtained. [Observation Results] Depending on the observation angle, from the gap (translucent portion) of the decorative film, the blue appearance in which the blue color on the back surface of the decorative film is reflected on the aluminum vapor deposition film as the base, and the appearance in which the vapor deposition film reflects the outside scenery, Furthermore, the appearance of the film surface,
They look at different distances, giving you an appearance with a prominent sense of depth. Also, at a certain viewing angle, the appearance of the outside scene is almost invisible, and the blue color on the film front surface and the blue color on the film back surface reflected on the film back surface appear to be almost blue. In this way, the various appearances appear to change continuously as the angle of the viewpoint changes, and the three-dimensional effect becomes outstanding. Example 20 The procedure described in Example 18 was repeated, but in this example, the layer structure of the decorative film was changed as shown in Table 6 below.

[0115]

[Table 6]

Here, both the colored layer and the clear layer were formed by using a polyurethane-based product which has a proven track record of being used outdoors in the field of automobile exteriors, and the colored layer was further colored with a blue pigment. Furthermore, an acrylic pressure-sensitive adhesive, which has a track record of being used outdoors, was used for forming the adhesive layer.

The appearance of the obtained emblem was observed while changing the observation angle perpendicular to the longitudinal direction of the stripe, and the following observation results were obtained. [Observation Results] Depending on the observation angle, the red appearance of the red on the back surface of the decorative film reflected on the aluminum vapor-deposited film of the base and the blue appearance of the film surface from the gap (translucent part) of the decoration film are Seen with contrast in both. At a certain angle, the appearance of the vapor-deposited film reflecting the outside scenery is also added. In this way, the various appearances appear to change continuously as the angle of the viewpoint changes, and the three-dimensional effect becomes outstanding. Example 21 The procedure described in Example 18 was repeated, but in this example, the layer structure of the decorative film was changed as shown in Table 7 below.

[0118]

[Table 7]

Here, the clear layer was formed by using a polyurethane-based product that has a track record of being used outdoors in the field of automobile exteriors. In addition, an acrylic pressure-sensitive adhesive, which has a track record of being used outdoors, was used to form the adhesive layer.

The appearance of the obtained emblem was observed while changing the observation angle perpendicular to the longitudinal direction of the stripe, and the following observation results were obtained. [Observation Result] Depending on the observation angle, the shadow of the film can be seen from the gap (translucent part) of the decorative film, and the external appearance can be seen reflected on the underlying aluminum vapor deposition film. Also,
At a certain angle, the shadow of the film is invisible and the whole looks like a uniform plating that reflects the outside scenery. In this way, the various appearances appear to change continuously as the angle of the viewpoint changes, and the three-dimensional effect becomes outstanding. Example 22 The procedure described in Example 18 was repeated, but in this example, the layer structure of the decorative film was not changed,
Before raising the transparent resin layer on the aluminum vapor deposition film side of the base material, red polyurethane ink (Sumitomo 3M
FL500 series ink), approx. 4 cm x
A 2 cm character design (3M) was silk screen printed.

The appearance of the obtained emblem was observed while changing the observation angle perpendicular to the longitudinal direction of the stripe, and the following observation results were obtained. [Observation Results] Depending on the observation angle, the blue appearance in which the blue color of the back surface of the decorative film is reflected on the aluminum vapor deposition film as the base from the gap (translucent portion) of the decorative film, the character design (3M) printed on the base material, and the film The appearance of the surface can be seen in different colors and at different distances, and an appearance with a prominent sense of depth can be obtained. Further, at a certain observation angle, the back surface of the film is invisible, and the entire design looks like a plating tone, and the character design (3M) looks like a fragment. In this way, the various appearances appear to change continuously as the angle of the viewpoint changes, and the three-dimensional effect becomes outstanding. Example 23 The procedure described in Example 18 was repeated, but in this example, the layer structure of the decorative film was changed as shown in Table 8 below.

[0122]

[Table 8]

Here, the base layer, the coloring layer and the clear layer were formed by using the products which have a track record of being used outdoors in the field of automobile exterior. For forming the adhesive layer, a heat-sensitive polyurethane adhesive, which has a track record of being used outdoors, was used.

On the base layer, a polka dot pattern (red and blue) pattern having a diameter of 2 mm (reverse pattern of FIG. 8B) was sequentially screen-printed to form a two-colored layer. The gap between adjacent dots was 2 mm. Then, the clear layer was screen-printed so as to cover the entire colored layer.

In the same manner as in Example 18, the decorative film was placed on the surface of the polyurethane transparent resin layer, and hot air was blown from above for 3 minutes for pressure bonding while heating. The decorative film which was heated and increased in flexibility covered the surface of the transparent resin layer and firmly adhered to the extent that it could not be peeled off by the action of the heat-sensitive polyurethane adhesive layer. The temperature of the resin surface and the decorative film at the time of application was higher than 80 ° C at the maximum. [Observation Results] Depending on the observation angle, the red appearance of the red on the back surface of the decorative film reflected on the aluminum vapor-deposited film of the base and the blue appearance of the film surface from the gap (translucent part) of the decoration film are Seen with contrast in both. At a certain angle, the appearance of the vapor-deposited film reflecting the outside scenery is also added. In this way, the various appearances appear to change continuously as the angle of the viewpoint changes, and the three-dimensional effect becomes outstanding.
