Abstract

PROBLEM TO BE SOLVED: To finish homogeneously metallic gloss on the surface of a molding transferred with a printed layer by hydraulic transfer, and obtain sufficient brightness feeling.SOLUTION: The surface of a plastic component 1 is degreased, and a clear varnish is coated thereon to form an under coat layer 2. Metal such as aluminum is deposited after the under coat layer 2 is dry to form a middle coat layer 3. Thereafter, an over coating agent of a urethane type is coated to form an over coat layer 4. A printed layer is transferred by hydraulic transfer after the overcoat layer 4 is dry. Specifically, a special film is floated on a water surface and a predetermined image printed on the film is transferred on the plastic component 1 by hydraulic transfer to form a three dimensional design layer 5. Further, a clear varnish is coated after the three dimensional design layer 5 is dry to form an over coat layer 6.

Description

  The present invention relates to a technique for uniformly finishing a metallic luster on the surface of a molded body to which a printing layer has been hydraulically transferred and realizing a sufficient brightness.

  Many plastic parts are used in gaming machines such as pachinko machines and slot machines. Among these parts, the ones that are placed on the parts that are visible to the player are more or less decorative. There are also parts whose main purpose is decoration.

For parts having such a decorative property, many surface decorations in which decoration is applied to the surface of the molded body by hydraulic transfer in order to improve design and quality have been put into practical use.
For example, in Patent Document 1, although it is a technical field related to automobile interior parts, the surface decoration product includes a resin molded body, a light emitting layer, a first clear coat layer, a printed layer, and a second clear coat layer. And the printing layer is hydraulically transferred onto the surface of the first clear coat layer.

  Here, hydraulic transfer means that a special film is floated on the surface of the water, and a predetermined pattern printed on the film (grain pattern, stone pattern, geometric pattern, hologram pattern, etc.) is applied to the surface of the molded body by water pressure. Transfer technology.

Further, when the fine unevenness is provided in the above-mentioned printed layer in a regular or uniform pattern, a hologram effect can be obtained.
In addition, in order to give metallic luster (so-called metallic) as a decorative effect, a technique is also known in which a printing layer is formed by applying a paint such as metallic color or clear color on a special film, and the printing layer is hydraulically transferred. It has been.

  However, in the above-described hydraulic transfer technology, when a paint such as a metallic color or a clear color is applied to a special film, the coating state is difficult to be uniform. There was a problem that the brightness on the surface of the body was difficult to be uniform.

  In addition, in order to finish the coating state on the special film uniformly, it is conceivable that the coating is repeated over and over again, but it is difficult to finish the coating state on the special film uniformly even if it is overcoated in this way. In addition, if unnecessary overcoating is performed, it is difficult to achieve a desired color tone and brightness.

Further, the water pressure transfer technique as described above has a problem that it is difficult to finish the surface of the molded body after water pressure transfer to a sufficient brightness.
The present invention has been made in view of such problems, and the object of the present invention is to uniformly finish the metallic luster on the surface of the molded body to which the printing layer has been hydraulically transferred and to achieve a sufficient brightness.

And a three-dimensional design layer formed by:

  According to the surface decoration product of the present invention configured as described above, the middle coat layer is formed by performing metal vapor deposition or metal plating on the undercoat layer formed on the surface of the resin molded body. Therefore, metallic luster is realized by this middle coat layer. As a result, the metallic gloss on the surface of the molded body to which the printing layer is hydraulically transferred can be uniformly finished and a sufficient brightness can be realized.

  The surface decorative article according to claim 2 is the surface decorative article according to claim 1, further comprising an undercoat layer, a middle coat layer, a first overcoat layer, and a three-dimensional layer formed on the surface of the molded body. A second overcoat layer formed by painting a clear or overcoat agent on the design layer is provided.

  According to the surface decorative article of the present invention configured as described above, the outermost layer is a second overcoat layer formed by painting a clear or overcoat agent, so that the surface of the surface decorative article is directly touched. Roughness is not felt and the second overcoat layer can prevent the three-dimensional design layer from falling off (eg, peeling).

  Further, the surface decorative article according to claim 3 is a metal molded body, an undercoat layer formed by painting clear on the surface of the molded body, and an undercoat formed on the surface of the molded body. And a three-dimensional design layer formed by hydraulic transfer of the printed layer from above the layer.

  According to the surface decoration product of the present invention configured as described above, a three-dimensional design layer is formed by hydraulically transferring a printed layer from above an undercoat layer formed on the surface of a metal molded body. Therefore, metallic gloss is realized by the surface of the molded body itself. As a result, the metallic gloss on the surface of the molded body to which the printing layer is hydraulically transferred can be uniformly finished and a sufficient brightness can be realized.

Embodiments of the present invention will be described below with reference to the drawings.
[First embodiment]
A gaming machine part (hereinafter referred to as a plastic part) 1 as a surface decoration product, which is an injection-molded product made of resin, is a part used for decoration of gaming machines such as pachinko machines and slot machines, and has an undercoat layer on its surface. 2, the middle coat layer 3, the overcoat layer 4, the three-dimensional design layer 5, and the overcoat layer 6 are configured in this order.

  The undercoat layer 2 is formed by painting clear on the surface of the plastic part 1 which is a base material. Note that the clear may be either colorless clear or colored clear, but if colored clear is used, coloring is also achieved. In addition, the degree of gloss (glossy, glossy, semi-glossy) can be adjusted by clearing. Also, the undercoat layer 2 may be formed by painting a urethane-based, acrylic-based, or vinyl chloride-based overcoat agent instead of clear.

  The middle coat layer 3 is formed by evaporating a metal such as aluminum from above the undercoat layer 2 formed on the surface of the plastic part 1. Instead of metal vapor deposition, the middle coat layer 3 may be formed by plating a metal such as chromium from above the undercoat layer 2 formed on the surface of the plastic part 1. In addition, about metal vapor deposition, the point which can adjust the transmittance | permeability with the thickness of a layer is advantageous compared with metal plating, and can exhibit a glittering feeling. If this metal vapor deposition is so-called half vapor deposition, for example, when a light source such as an LED is disposed behind the plastic part 1, a later-described three-dimensional design layer 5 can be shone in a complicated and shining manner. On the other hand, metal plating such as chromium does not exhibit a glittering feeling because it does not transmit light, but can exhibit a profound feeling due to metallic luster.

  The overcoat layer 4 is formed by applying a urethane overcoat agent on the undercoat layer 2 and the middle coat layer 3 formed on the surface of the plastic part 1. An acrylic or vinyl chloride overcoat agent may be used instead of the urethane overcoat agent. In particular, when the overcoat layer 4 is formed using a urethane-based overcoat agent, it has been experimentally confirmed that a three-dimensional design layer 5 described later can be easily transferred from above. Moreover, you may form the overcoat layer 4 by painting clear instead of an overcoat agent.

  The three-dimensional design layer 5 is formed by hydraulically transferring a printing layer from above the undercoat layer 2, the middle coat layer 3 and the overcoat layer 4 formed on the surface of the plastic part 1. Hydraulic transfer means that a special film is floated on the surface of the water, and a predetermined pattern printed on the film (a pattern of wood grain, stone pattern, geometric pattern, hologram, etc.) is applied to the surface of the plastic part 1 by water pressure. This is a known technique for transferring.

  The overcoat layer 6 is formed by painting clear on the undercoat layer 2, the middle coat layer 3, the overcoat layer 4 and the three-dimensional design layer 5 formed on the surface of the plastic part 1. In addition, you may form the overcoat layer 6 by painting the above-mentioned overcoat agent instead of clear.

  This layer structure was formed as follows. First, the surface of the plastic part 1 is degreased, and clear is applied here (undercoat layer 2, first step). Instead, an overcoat agent may be applied. After waiting for the undercoat layer 2 to dry, a metal such as aluminum is deposited (middle coat layer 3, second step). Alternatively, metal plating may be applied. Next, a urethane-based overcoat agent is applied (overcoat layer 4, third step). Instead, an acrylic or vinyl chloride overcoat agent may be used, or clear may be applied. After waiting for the overcoat layer 4 to dry, the printing layer is hydraulically transferred. Specifically, a special film is floated on the water surface, and a predetermined pattern printed on the film is transferred onto the surface of the plastic part 1 by water pressure (three-dimensional design layer 5, fourth step). Then, after waiting for the three-dimensional design layer 5 to dry, the clear is applied (overcoat layer 6, fifth step). Instead, an overcoat agent may be applied.

  Since the plastic part 1 has the surface structure as described above, metallic gloss is realized by the middle coat layer 3. As a result, the metallic luster on the surface of the plastic part 1 to which the printing layer is hydraulically transferred can be uniformly finished and a sufficient brightness can be realized.

  Moreover, since the outermost layer is the overcoat layer 6 formed by clearing or coating the overcoat agent, even if the player directly touches the surface of the plastic part 1, the player does not feel roughness, and the overcoat layer 6 It is possible to prevent the three-dimensional design layer 5 from dropping (peeling off).

As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, It is possible to implement in various aspects.
In the above embodiment, an example in which the present invention is applied to a gaming machine part which is a resin injection molded product has been described. However, if it is a resin molded product, it is used for various products such as automobiles, mobile phones, personal computers, and the like. The present invention can also be applied to various types of parts.

[Second Embodiment]
A gaming machine part (hereinafter referred to as a metal part) 11 as a surface decoration, which is a metal molded body, is a part used for decoration of a gaming machine such as a pachinko machine or a slot machine. The three-dimensional design layer 13 and the overcoat layer 14 are layered in this order.

  The undercoat layer 12 is formed by painting clear on the surface of the metal part 11 serving as a base material. Note that the clear may be either colorless clear or colored clear, but if colored clear is used, coloring is also achieved. In addition, the degree of gloss (glossy, glossy, semi-glossy) can be adjusted by clearing. Further, the undercoat layer 12 may be formed by painting a urethane-based, acrylic-based, or vinyl chloride-based overcoat agent instead of clear.

  The three-dimensional design layer 13 is formed by hydraulic transfer of the printing layer from above the undercoat layer 12 formed on the surface of the metal part 11. Since the water pressure transfer has been described above, a detailed description thereof is omitted here.

  The overcoat layer 14 is formed by painting clear on the undercoat layer 12 and the three-dimensional design layer 13 formed on the surface of the metal part 11. In addition, you may form the overcoat layer 14 by painting the above-mentioned overcoat agent instead of clear.

  This layer structure was formed as follows. First, the surface of the metal part 11 is degreased, and clear is applied here (undercoat layer 12, first step). Instead, an overcoat agent may be applied. After waiting for the undercoat layer 2 to dry, the printing layer is hydraulically transferred. Specifically, a special film is floated on the water surface, and a predetermined pattern printed on the film is transferred onto the surface of the plastic part 1 by water pressure (three-dimensional design layer 13, second step). Then, after waiting for the three-dimensional design layer 13 to dry, clear is applied (overcoat layer 14, third step). Instead, an overcoat agent may be applied.

  Since the metal part 11 has the surface structure as described above, metallic gloss is realized by the surface of the metal part 11 itself. As a result, the metallic luster on the surface of the metal part 11 to which the printing layer is hydraulically transferred can be uniformly finished and a sufficient brightness can be realized.

  Further, since the outermost layer is the overcoat layer 14 formed by clearing or applying an overcoat agent, even if the player directly touches the surface of the metal part 11, the player does not feel roughness, and the overcoat layer 14 It is possible to prevent the three-dimensional design layer 13 from dropping (peeling off).
