Description

  The present invention relates to a decorative body.

  As is well known, silver is an elegant luster and is a malleable metal, so it has been thinly cast into a foil (silver foil) for a long time, or the foil is crushed into a powder (silver foil) It is used as a decorative material for kimonos and crafts.

  In recent years, decorative materials using vacuum deposition technology, which is a substitute for silver foil or silver foil powder, have been developed. For example, Patent Document 1 listed below discloses at least a pigmented resin coating film A and a metal thin film B. A colored foil is disclosed in which these are closely stacked by vacuum deposition in the order of A / B / A, and the coloring described in Patent Document 1 described later is disclosed. A colored powder obtained by pulverizing a foil is disclosed.

  However, when silver is exposed to air for a long period of time, it reacts with sulfur components in the air to become silver sulfide, which has the property of losing luster due to blackening. Therefore, when using each of the above decoration materials In order to suppress discoloration, silver is used in a form coated with a transparent resin so as not to touch the air. For example, in Patent Document 3 described later, the surface of a sphere made of a shell is made of resin. There has been disclosed a decorative bead having a noble metal luster formed by attaching a noble metal foil such as gold, silver, or platinum and coating a transparent resin thereon.

  Further, when the decoration materials are used for decoration of kimonos such as kimonos and belts for a long time, they are used as liquid materials (silver mud) in which the decoration bodies are dispersed in glue made of water.

On the other hand, in recent years, attention has been paid that silver ions released from silver have a bactericidal effect against pathogenic bacteria such as Salmonella and staphylococci, and that silver is a metal with extremely low toxicity to the human body. Therefore, many daily necessities using these silver-specific effects have been developed.

  However, in order to obtain the sterilizing effect of silver, it is necessary to directly contact the silver itself with air or water, and when used in a state where silver is dispersed in the resin as in the case of using as a decoration material, the silver is a resin. As a result, it cannot be directly contacted with air or water, and a sterilizing effect cannot be obtained.

  That is, when obtaining a silver bactericidal effect, it is necessary to use silver in an exposed form in order to contact air or water, whereas when obtaining a silver decorative effect, silver discoloration is required. Therefore, it is necessary to use in such a manner that it is not exposed, and it is very difficult to obtain both effects at the same time.

  Therefore, the present invention provides a decorative body capable of obtaining a decorative effect while suppressing the discoloration of silver and also obtaining a bactericidal effect, and has been made as a prototype / experiment in order to achieve its realization. As a result of repeating the above, after applying an adhesive to the surface of the object to be decorated, the object to be decorated is submerged in a silver foil powder obtained by pulverizing the decorative foil in which both surfaces of the silver foil as the punched foil are coated with resin. If the decorative powder adheres to the surface of the object to be decorated by alternately repeating the process of adhering to the surface of the object to be decorated and the operation of removing excess decorative powder adhering to the surface of the object to be decorated, The present invention has achieved the above technical problem by obtaining a remarkable knowledge that the silver foil exposed in the cross section is exposed on the surface of the decorative body, and the discoloration of the silver foil is also suppressed.

  The technical problem can be solved by the present invention as follows.

  That is, the decorative body according to the present invention is obtained by adhering a decorative powder obtained by pulverizing a decorative foil in which both surfaces of a silver foil as a punching foil are coated with a resin to an adhesive applied to the surface of the decorative body. .

  Further, the present invention provides an operation for applying the decorative powder to the surface of the object to be decorated by applying an adhesive to the surface of the object to be decorated and then submerging the object to be decorated in the silver foil powder. The decoration powder is adhered to the surface of the object to be decorated by alternately repeating the operation of removing excess decoration powder adhered to the surface of the decoration body.

  Moreover, the method for producing a decorative body according to the present invention includes applying an adhesive to the surface of the object to be decorated, and then pulverizing the decorative foil in which both sides of the silver foil that is the punched foil are coated with a resin into the silver foil powder. The decoration powder is applied to the surface of the object to be decorated by alternately repeating the operation of diving the object to be decorated and adhering to the surface of the object to be decorated and the operation of removing excess decoration powder adhering to the surface of the object to be decorated. It is what is attached.

  According to the present invention, the decorative powder having a structure in which both surfaces of the silver foil are coated with the resin layer is fixed on the surface of the object to be decorated, so that the silver foil exposed from the cross section of the decorative powder appears on the surface of the decorative body, When silver is brought into contact with air or water, silver ions are released and a bactericidal effect can be obtained. Moreover, since the silver foil which is a punching foil was used as a silver layer of decoration powder instead of the silver film formed by vapor deposition, the spread of the discoloration which advances from the edge of the silver foil exposed from the cross section of the decoration powder to the center is suppressed. be able to. This is presumably because the silver foil as the punched foil is thicker than the silver film formed by vapor deposition and the structure is different.

  Therefore, it can be said that the industrial applicability of the present invention is very high.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
