Description

  The present invention is applied to, for example, a vehicle rear window outer surface, a store glass outer surface, a wall surface in a house, or a hard surface of a bag, a mobile phone, or other everyday items, or a shirt or other clothing or sewing product. The present invention relates to a decorative sheet for applying decoration on the surface of fabrics, leather goods, etc., and aims to simplify decoration work and improve design.

  Conventionally, it has been practiced to obtain a decorative effect by sticking a small number of decorative bodies such as crystal glass or sequins on a hard surface such as plastic, glass or metal by a design arrangement. In this case, an adhesive is usually applied to the bottom of a decorative body such as crystal glass, and this is adhered to a compact state while manually laying out a large number of pieces one by one to finally obtain the desired design. It is.

However, the above manual method requires a lot of labor and time, and there is also a problem that it is difficult to obtain a high-quality design effect. Recently, a base sheet is used and a decorative pattern is applied on the base sheet in advance. In addition, it is known that a large number of decorative grains are attached to the decorative pattern through an adhesive layer, and a release sheet is attached to the back surface of the base material sheet through an adhesive layer (utility model registration). No. 3110694).
Utility Model Registration No. 3110694

  However, the one described in Patent Document 1 uses a base sheet on which a decorative pattern is drawn on the surface, and is decorated in a complementary relationship between the color of the decorative pattern represented on the base sheet and a large number of decorative grains. Because it is used as a base sheet and attached to an object such as a mobile phone or a lighter, it can be applied to the object as it is while maintaining the design of many decorative grains. On the other hand, it has the advantage of being able to do so, but the texture of the object itself at the periphery of each decorative grain is concealed, resulting in concealing part of the individuality of the object at the corner, which is not very popular.

  Therefore, in the present invention, a large number or at least a plurality of decorative particles can be attached to the surface of the object in a simple and beautifully designed state without impairing the texture of the surface of the object. Specifically, a tack film having a pressure-sensitive adhesive on the back surface and a pressure-sensitive or heat-sensitive pressure-sensitive adhesive on the bottom surface, or a hot-melt pressure-sensitive pressure-sensitive adhesive having both pressure-sensitive and heat-sensitive functions At least a plurality of decorative particles adhered to the back surface of the tack film according to the design arrangement with the upper end surface being inverted in an upside down state, and polymerized and pasted on the back surface of the tack film with the decorative particles interposed therebetween The present invention relates to a decorative sheet comprising a release sheet.

  As described above, the present invention applies a pressure-sensitive or heat-sensitive adhesive or a hot-melt pressure-sensitive adhesive having both pressure-sensitive and heat-sensitive functions to the bottom surface and tacks the top surface in an inverted state. Since each decorative grain is pasted in a state of design arrangement on the adhesive surface on the back side of the film, simply peel off the release sheet on the back side of the tack film and hold both ends, and this is the glass or metal surface that is the object Then, the decorative grains are pressed from the upper surface of the tack film with a fingertip for each decorative grain, or the decorative grains are pressed together on a flat surface to be adhered.

  Furthermore, the above-mentioned tack film is peeled off and removed from each decorative grain, so that a decoration having a high-quality design can be easily applied in a state where the properties and texture of the surface of the decoration object are represented as they are. . In this case, when the pressure-sensitive adhesive applied to the bottom of each decorative grain is a hot-melt pressure-sensitive pressure-sensitive adhesive having both pressure-sensitive and heat-sensitive functions, not only a smooth surface such as glass or metal The shirt, leather, or woven fabric can be decorated with sufficient adhesive strength by the so-called hot melt method.

  In the following, the specific contents of the present invention will be described based on the embodiment shown in FIGS. 1 and 2, wherein 1 is a tack film, 3 is a decorative grain, and 5 is a release sheet. As the tack film 1, for example, a flexible sheet such as a polyethylene resin or a heat-resistant polyester resin is used, and a transparent sheet is used in the present embodiment. Further, an adhesive 2 is applied to the back surface of the tack film 1.

  Regarding the adhesive 2 used here, when the decorative film 3 is sufficiently attached and held on the tack film 1 in an inverted state, and transferred onto the object, the tack film 1 is removed. In addition, a pressure-sensitive material having a pressure-sensitive adhesive strength 3 that is relatively weak enough to prevent the attached decorative particles 3 from being peeled off from the object is preferable. Illustrative examples of such a case include Sairevine (registered trademark) and Olivevine (registered trademark) of Toyo Ink Co., Ltd. Siavine is a urethane-based adhesive, and is particularly excellent in re-peeling compared to general acrylic adhesives. These adhesive materials can be used by thinly coating the entire back surface of the tack film in advance. Of the known pressure-sensitive adhesives, any medium-peelable one having a thickness of about 100 mN to 1,000 mN / 25 mm can be used as the pressure-sensitive adhesive 2 described above.

  The decorative grain 3 is made of crystal glass in the present embodiment, but is not necessarily limited to this, and any of them can be used as long as they are useful for decoration such as crystal or topaz. . The decorative grain 3 used in this embodiment is a polyhedron with a flat bottom surface and a peripheral side surface that is diamond-shaped. The upper end surface is a flat surface with a small area, and is inclined from the side surface to the upper end surface. (Substantially trapezoidal shape) is used.

  Further, an adhesive 4 is applied to the bottom surface of the decorative grain 3 in advance. The pressure-sensitive adhesive 4 may be one in which another pressure-sensitive pressure-sensitive adhesive material such as siabine or olivine described above is applied thickly. In addition, when the pressure-sensitive adhesive used here has both pressure sensitivity and heat sensitivity, not only the hard materials such as glass and plastic described above but also shirts and the like as objects to which a large number of decorative grains 3 are designed and attached. It is also possible to apply it to the surface of clothing, sewing products, fabrics, leather goods, etc., by a so-called hot melt method in which fluidity is imparted by heating and melting.

  As pressure-sensitive adhesive and heat-sensitive adhesive, among various conventionally used pressure-sensitive adhesives, those with excellent adhesive properties such as acrylic and urethane synthetic rubber systems, and excellent peelability, Moreover, the thing which can exhibit a heat-sensitive adhesive force by applying heat is good. Of these, acrylic hot melt adhesives are preferred, and specific examples thereof may include the product name “Durotac PZ series” of NSC Corporation, and the product name “Nichigo Polyester” of Nippon Synthetic Chemical Industry Co., Ltd. ”May be diluted.

  In addition, the product name “Acrymelt” from No-Tape Industries Co., Ltd. or a thermal composite of polyethylene and gauze fibers was used as a base material, a release agent was applied to the vinyl surface, and a hot melt pressure-sensitive adhesive was applied to the fiber surface The cloth-like tape of Shanghai Yongkang Glue Products Co., Ltd., brand name “YG”, etc. can also be used. Furthermore, it can be realized by applying a hot melt type pressure sensitive adhesive described in Japanese Patent No. 2730986 or Japanese Patent No. 2743288.

  As the heat-sensitive adhesive used here, a known resin-based heat-sensitive adhesive such as an adhesive mixture based on a thermoplastic polymer may be used. In this case, if a large number of decorative grains 3 which are somewhat inferior in pressure-sensitive adhesive force are applied to the surface of clothing, sewing products, fabrics, leather products, etc., they are not simply bonded and fixed to the surface of clothing, etc. It is possible to use it by sticking it as a seal by simply pressing it, and it can be easily peeled off at a later date.

  The release sheet 5 is polymerized on the back surface of the tack film 1 for the purpose of preventing the dirt of the adhesive applied to the back surface of the tack film 1 and protecting the decorative particles 3 held on the back surface of the tack film 1. It is attached to the tack film 1 in a temporary adhesive state, and is not applied with an adhesive or the like, and has a small interaction with the adhesive 4 and is peeled off from the tack film 1 When the sheet 5 is peeled off, the adhesive 4 or the like applied to the bottom surface of a large number of decorative particles 3 is easily peeled off, and when the tack film 1 is peeled off, the decorative particles 3 fall from the back surface of the tack film 1 The material must not be

  Preferable materials for the release sheet 5 having such a function include light release properties of about 100 mN or less / about 25 mm, for example, various resin sheets obtained by applying a silicone treatment to paper or the surface. In the above embodiment, the tack film 1 is transparent, but may be a translucent or opaque coloring material film.

  In the configuration of the present invention described above, first, the release sheet 5 on the back side of the tack film 1 is peeled off, and the side on which the decorative particles 3 are held with both ends of the tack film 1 is placed on the surface of the target object. Then, the portions of the decorative grains 3 are sufficiently pressed against the object from the surface side of the tack film 1 and adhered. In this case, when a planar pressing material is used, each decorative grain 3 can be simultaneously adhered to the object, which is efficient. After each decorative grain 3 is sufficiently pressed and adhered to the object, the tack film 1 is peeled off from the upper end surface of each decorative grain 3 to complete the decoration work.

  When the adhesive 4 applied to the bottom of each decorative grain is a heat-sensitive hot melt adhesive, the side on which the decorative grain 3 is held with both ends of the tack film 1 is intended. After aligning and superposing on the surface of the object to be pressed, the decorative particles 3 are pressed against the object and heated from the surface side of the tack film 1 using a heating tool such as an iron. 4 is melted and fluidized, soaked in fibers and bonded.
