Description

  The present invention relates to a surface decoration article having a surface decorated by forming a transparent resin layer on a printed pattern applied to the surface of the article by an appropriate means, and an article surface decoration method suitable for forming the surface decoration article. It is about.

  The surface of an article having a three-dimensionally complex surface is decorated by various means, and the most suitable method for decorating the surface of an article having such a complex surface is hydraulic pressure. This is a transfer method.

  In this water pressure transfer method, a transfer film having a predetermined water-insoluble printing pattern formed on a water-soluble film is sequentially supplied and floated on the water surface flowing in the transfer tank, and the transfer film is wetted with water. Then, the article (object to be transferred) is immersed in water in the transfer tank while being in contact with the transfer film, and the printing pattern on the transfer film is transferred to the surface of the article by using water pressure to print the layer (decoration layer) It is a method of forming.

  The article whose surface is thus decorated has a transparent resin surface protective layer (top coat) covering the surface of the printed pattern in order to impart physically and chemically stable characteristics to the printed layer. The surface protective layer is formed, for example, by applying a normal solvent-based transparent paint using a spray gun.

  On the other hand, recently, a large number of convex lens-shaped protrusions are formed on the surface of the transparent sheet as a decorative sheet in an arbitrary continuous pattern, and a pattern having a continuous pattern substantially the same as the continuous pattern of protrusions is formed on the back surface of the transparent sheet. A decorative sheet formed by printing while being displaced with respect to a pattern has been proposed (see Patent Document 1).

  Since the pattern of this decorative sheet changes depending on the viewing direction, it is possible to give a unique decorative property to the object on which the decorative sheet is attached. However, this decorative sheet is suitable for use by being attached to a structure such as a wall, but is not suitable for adhering to an article having a complicated three-dimensional surface for decoration.

  One problem to be solved by the present invention is to provide a surface-decorated article capable of applying a decoration whose pattern changes depending on the viewing direction to an article having a complicated three-dimensional surface.

  Another problem to be solved by the present invention is an article surface decoration method capable of easily obtaining a surface decoration article capable of applying a decoration whose pattern changes depending on the viewing direction on an article having a complicated three-dimensional surface. It is to provide.

  A first problem solving means of the present invention comprises a printed pattern formed on a three-dimensional surface of an article and a surface protective layer of a transparent resin covering the printed layer, and a convex lens-like many are formed on the surface protective layer. It is another object of the present invention to provide a surface decorative article characterized in that the protrusion is formed.

  In this first problem solving means, a number of convex lens-shaped protrusions form an arbitrary continuous pattern, and the printing layer has a continuous pattern that is substantially the same as the continuous pattern of convex lens-shaped protrusions and has a convex lens shape. It is preferable to have a pattern displaced with respect to the continuous pattern of protrusions.

  In particular, the printing layer can be formed by hydraulic transfer of a pattern printed on a water-soluble film, and the convex lens-shaped protrusions can also be transferred by hydraulic transfer of an ultraviolet curable transparent resin paint applied on the water-soluble film. Can be formed.

  More preferably, the printing layer can be formed by hydraulic transfer of a pattern printed on a water-soluble film, and the surface protective layer and convex lens-like protrusions are also coated on the water-soluble film. The resin paint can be formed by hydraulic transfer.

  The third problem-solving means of the present invention includes a step of hydraulically transferring a printed layer on a water-soluble film onto the surface of an article, and a step of forming a surface protective layer of a transparent resin on the printed layer transferred onto the article; In the method for decorating an article surface comprising: a step of forming a number of convex lens-shaped protrusions on the surface protective layer, the step of forming the surface protective layer and the step of forming the protrusions on a water-soluble film A UV curable transparent resin paint printed in a dotted uneven pattern is hydraulically transferred onto a printed layer transferred onto an article to form a surface protective layer and a large number of convex lens-shaped protrusions simultaneously. An object of the present invention is to provide a surface decoration method for an article characterized in that it is carried out in the step.

  In the second and third problem solving means, a recess corresponding to the convex lens-shaped protrusion is formed on the water-soluble film, and the ultraviolet curable transparent resin coating is printed in a state of being embedded in the recess. It is preferable that the paint substance in the depression is formed into a convex lens-like projection by being hydraulically transferred onto the article.

  In addition, a large number of convex lens-shaped protrusions form an arbitrary continuous pattern, and the printing layer is a continuous pattern that is substantially the same as the continuous pattern formed by the convex lens-shaped protrusions and is continuous with the continuous pattern of convex lens-shaped protrusions. It is preferable to have a pattern that is displaced.

  In this way, when a large number of convex lens-like protrusions are formed on the surface protective layer of the transparent resin that covers the printed layer formed on the three-dimensional surface of the article, the surface protective layer is used for surface protection and printing of the printed layer. It is possible to impart variability such as a three-dimensional effect to the layer, and to give unique decorative properties to articles having complex surfaces.

  In particular, when a surface protective layer and a large number of convex lens-like protrusions are formed on the surface of an article using a hydraulic transfer technology, it is very easy to print on a complex surface, protect the surface and impart pattern change. These operations can be performed with high efficiency.

  Further, when the surface protective layer and a large number of protrusions of the article are formed by hydraulic transfer of an ultraviolet curable transparent resin paint, it is possible to form physical and chemically excellent surface protective layers and protrusions that impart pattern changeability. And the life of the decorative article can be improved.

  An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a surface decoration article 10 according to one embodiment of the present invention, and the surface decoration article 10 is a print having a predetermined pattern. An article body 12 having a three-dimensional surface on which a layer 14 is formed, and the surface decorative article 10 includes a surface protective layer 16 of a transparent resin that covers the printed layer 14 of the article body 12. A plurality of convex lens-shaped projections 18 are formed.

  As shown in FIG. 2, the convex lens-shaped many projections 18 form an arbitrary continuous pattern, and the printing layer 14 has a continuous pattern substantially the same as the convex lens-shaped projection 18 and is a convex lens. It is preferable to have a pattern that is displaced with respect to the continuous pattern of the projections 18.

  The article body 12 can be made of any material such as metal, plastic, wood, and the printed layer 14 can be applied to the three-dimensional surface of the article body 12 by any means. However, as will be described in detail later, it is particularly preferable to apply by a hydraulic transfer means.

  The surface protective layer 16 made of transparent resin is preferably applied by means of a conventional technique such as spray means for forming with a certain layer thickness. However, as will be described in detail later, the surface protective layer 16 is also formed by a hydraulic transfer means. It can also be applied.

  As described above, when a large number of convex lens-shaped protrusions 18 are formed on the surface protective layer 16 of the transparent resin that covers the printed layer 14 formed on the three-dimensional surface of the article body 12, the surface protective layer 16 is printed. At the same time as protecting the surface of the layer 14, the printed pattern 14 changes depending on the viewing direction, appears to sink, or appears to float, thereby imparting pattern changeability to the printed layer 14. As described above, when pattern changeability is imparted to the printed layer 14, unique decorative properties can be imparted to the article 10 having a complicated surface.

  The phenomenon in which the pattern appears to change depending on the viewing direction of the printing layer 14 will be described in detail. As shown in FIG. 3, the pattern of the printing layer 14 and the surface protection layer 16 are viewed from directly above the surface protection layer 16. Depending on the position of the protrusion 18 having a convex lens shape, the whole overlaps or partially overlaps. As shown in FIG. 3A, when the pattern portion 14P of the printing layer 14 completely overlaps the protrusion 18 of the surface protective layer 16, the pattern portion 14P of the printing layer 14 is recognized from any direction. On the other hand, as shown in FIG. 3B, when the pattern portion 14P of the printed layer 14 partially overlaps with the protrusion 18 of the surface protective layer 16, the pattern is viewed from the non-overlapping portion in the direction of arrow A. Although the portion 14P is not recognized, the pattern portion 14P is recognized when viewed from the direction of the arrow B where there is an overlap. Accordingly, the pattern portion 14P of the print layer 14 is visible, disappears, sinks, or floats depending on the overlapping state of the pattern portion 14P of the print layer 14 and the convex lens-shaped protrusion 18 as described above. It changes when you see it.

  In particular, as shown in FIG. 2, if the printed layer 14 has a pattern that is substantially the same as the continuous pattern of the convex lens-shaped protrusions 18 and is displaced with respect to the continuous pattern of the convex lens-shaped protrusions 18, the peculiarity It is preferable because the decorative property can be further improved.

  Note that the convex lens-shaped protrusion 18 can have any form, but as shown in FIG. 3, it is particularly preferably hemispherical or bowl-shaped.

  In the surface decorative article 10 of the present invention, the printing layer 14 and the surface protective layer 16 and the protrusions 18 thereof can be formed by any means, but most preferably, the printing layer 14 is a hydraulic transfer means, that is, water-soluble. The pattern printed on the film can be formed by a hydraulic transfer method, and the convex lens-shaped protrusion 18 also hydraulically transfers the hydraulic transfer means, that is, the ultraviolet curable transparent resin coating applied on the water-soluble film. It can be formed by a method.

  In this case, not only the convex lens-shaped protrusions 18 but also the surface protective layer 16 can be formed together with the convex lens-shaped protrusions by hydraulic transfer of an ultraviolet curable transparent resin coating applied on the water-soluble film.

  Further, the convex lens-shaped protrusions can have various forms, but are preferably hemispherical or bowl-shaped.

  A method for decorating the surface of an article by forming a printed layer 14, a surface protective layer 16 and a large number of protrusions 18 on the article body 12 by hydraulic transfer means according to the present invention is shown in FIG.

  First, as shown in FIG. 4A, the article body 12 is immersed in water 26 in a transfer tank through a transfer film 20 for hydraulic transfer of the printing layer 14 to the article body 12 so that the printing layer 14 is formed. It is formed (see FIG. 14B).

  As shown in FIG. 5, the transfer film 20 absorbs water and wets and softens, for example, a water-soluble film 20F made of a water-soluble material mainly composed of polyvinyl alcohol and gravure printing on the water-soluble film 20F. The printing pattern 20 </ b> P is applied by the above method.

  The transfer film 20 is floated on the water 26 in the transfer tank 22 so that the print pattern 20P is on the water surface in the transfer tank, and the print pattern 20P is applied to the surface of the article body 12 by the water pressure received by the immersion of the article body 12. Transcript to. When the printing pattern 20P is in a dry state, it is restored to a wet state equivalent to that immediately after printing by an appropriate ink activator such as a solvent before immersion.

  Next, as shown in FIG. 4C, the article body 12 is placed in the transfer tank via a transfer film 22 for hydraulically transferring the surface protective layer 16 and the protrusions 18 onto the printing layer 14 on the article body 12. The surface protective layer 16 and the protrusions 18 are formed by being immersed in water 26 (see FIG. 14D).

  As shown in FIG. 6, the transfer film 22 is made of a water-soluble film 22F made of, for example, a water-soluble material mainly composed of polyvinyl alcohol, and the water-soluble film 22F by an appropriate printing method. It consists of the applied ultraviolet curable transparent resin coating 22P. As illustrated, a recess 22Fc corresponding to the convex lens-shaped protrusion 18 is formed on the water-soluble film 22F, and the ultraviolet curable transparent resin coating 22P is printed so as to be embedded in the recess 22Fc. The coating material 22Pc in the recess 22Fc of the ultraviolet curable transparent resin coating 22P becomes the convex lens-shaped protrusion 18, and the coating material layer portion 22Ps thereon becomes the surface protective layer 16.

  The transfer film 22 is floated on the water 26 in the transfer tank so that the ultraviolet curable transparent resin paint 22P is on the water surface of the water 26 in the transfer tank, and the printing layer 14 is applied by the water pressure received by the immersion of the article body 12. Transcript onto.

  After the transfer, the ultraviolet curable transparent resin coating 22P is cured by being irradiated with ultraviolet rays, whereby the surface protective layer 16 and the protrusions 18 are formed.

  In the form of FIG. 4, the surface protective layer 16 and the protrusions 18 are simultaneously formed by the hydraulic transfer means. However, the surface protective layer 16 is formed by a hydraulic transfer means or a spray means in a separate process from the protrusions 18, The protrusion 18 may be formed by hydraulic transfer.

  In this case, as shown in FIG. 7, the transfer film 24 for transferring the protrusions is formed by printing the ultraviolet curable transparent resin coating 24P printed in a dotted pattern on the water-soluble film 24F in a dotted pattern. can do.

The ultraviolet curable coatings 22P and 24P are made of components having the following composition, for example.
(1) Oligomer 30-50% by weight
(2) 10-30% by weight of polyfunctional acrylate
(3) Monofunctional acrylate 10-40% by weight
(4) Non-reactive additive 1-20% by weight
(5) Photoinitiator 0.5-5% by weight
(6) Solvent balance

  The oligomer is a component that affects the adhesion and physical properties of the paint, but any one of acrylic oligomer, polyester oligomer, epoxy acrylate oligomer, urethane acrylate oligomer, etc. can be used alone or arbitrarily depending on the desired properties. Can be used in combination.

  The monofunctional acrylate monomer is a reactive diluent, and the polyfunctional acrylate monomer is a crosslinking component, and imparts excellent chemical and mechanical properties to the paint after UV curing.

  Polyacrylates such as polymethyl acrylate are used for the purpose of relaxing the shrinkage effect of the coating film due to the crosslinking component. When the shrinkage force of the coating film increases, the adhesion of the coating film decreases, which is useful for preventing this.

  As the photoinitiator, known ones such as acetophenone and benzophenone can be used, and as the solvent, ethyl acetate, butyl acetate, propylene glycol monomethyl alcohol acetate, anone, toluene, xylene and the like can be used.

  The UV curable transparent paint can be applied to the water-soluble films 22F and 24F by any one of printing techniques such as gravure printing, screen printing, pad printing, and ink jet printing, or spray coating technique. Since it can be cured in time, it can be suitably formed by transfer without significantly reducing the shape of the convex lens-like projections as the print pattern.
