Abstract

PURPOSE:To ensure that a change over time in a pattern can hardly occur and the pattern looks presentable by covering the face of an opposite side to an enclosure side of the pattern with an auxiliary film which reflects an ultraviolet beam. CONSTITUTION:A pattern 7 is printed on the face to which an enclosure is pressed of a film 16, and the face of an opposite side to an enclosure side of the pattern 7 is covered with an auxiliary film 1 which reflects an ultraviolet beam. When attaching a transfer sheet 6 thus obtained to the enclosure, first a parting paper is peeled off and the peeled off face side is attached to the enclosure. Then after rubbing the surface (transparent resin film 16) of the transfer sheet 6 using a fixture, the transparent resin film 16 is peeled off. Thus it is possible to ensure that a change over time hardly occurs in the pattern 7 or ink due to an ultraviolet beam by covering the face of the opposite side to the enclosure side of the pattern 7 with the auxiliary film 15 which reflects an ultraviolet beams. In addition, it is possible to ensure that the pattern 7 can hardly occur due to the strength of the auxiliary film 15.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer sheet for transferring a pattern to an exterior body (for example, an outdoor heat exchange unit of a separation type air conditioner).

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open No. 4-169296 discloses a method of transferring a design of a transfer sheet onto an exterior body.

The transfer method shown in this publication is as follows. First, a design is applied to the back surface of the film, and the back surface is pressed against the exterior body to adhere the design to the exterior body. Here, the surface of the pattern was covered with a substantially transparent ink which was cured by applying ultraviolet rays (UV curing type). By covering the surface of the design with such an ink, the fading of the design is prevented or the design is protected.

[0004]

Although the above-mentioned ink is cured by applying ultraviolet rays in advance before adhering the design to the exterior body, the exterior body is placed outdoors and the ultraviolet rays are left for a long time or intermittently. In some cases, the ink may be further cured when it is applied to the outer package or due to aging. Due to the curing of the ink, the difference in the expansion coefficient of the adhesive for adhering the ink to the exterior body, the paint of the design, etc., cracks may occur in the design, and the appearance of the design may deteriorate.

An object of the present invention is to prevent the secular change of the design applied to the exterior body and to keep the appearance of the design good.

[0006]

In order to achieve this object, the present invention provides a design on the pressing surface of the film to be pressed against the exterior body, and the surface on the side opposite to the exterior body of this design is exposed to ultraviolet rays. It is covered with a reflective auxiliary film.

[0007]

Function: The surface of the pattern applied to the exterior body is covered with an auxiliary film that reflects ultraviolet rays, so that the patterns and inks are less likely to change with time due to ultraviolet rays. Further, the strength of this auxiliary film makes it difficult for the pattern to be deformed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 is an outdoor heat exchange unit of a separation type air conditioner in which a heat exchanger, a blower, a compressor and the like are housed. This outdoor heat exchange unit 1
The outer casing 2 is formed by bending a sheet metal.
3 is an outlet grille, 4 is a valve cover, and 5 is an electric equipment lid. Reference numeral 6 is a transfer sheet attached to the front surface of the exterior body 2 as indicated by a solid arrow. The transfer sheet 6 has “I
The character (design) 7 "NVERTER" is applied by the method described later. Reference numeral 8 is a jig for pressing the transfer sheet against the exterior body 2.

2 and 3 show the transfer sheet 6, 9 is a release paper, 10 is a first adhesive layer applied on the release paper 9, and the first adhesive layer 10 is an acrylic type. Alternatively, it is composed of a urethane-based solvent type adhesive.
11 is a second adhesive layer applied on the first adhesive layer 10,
The second adhesive layer is composed of an adhesive which is cured by ultraviolet rays (which is called "UV curing type"). Then, after applying this UV-curable adhesive on the first adhesive layer 10,
Light this adhesive to a lamp that emits ultraviolet light,
The adhesive is cured. Reference numeral 12 denotes a medium layer provided on the second adhesive layer. By providing the medium layer 12, an ink layer described later is easily attached. Reference numeral 13 is an ink layer, and the above-mentioned character 7 "INVERTER" is applied by this ink layer. The medium layer 12 and the ink layer 13 described above are also the second adhesive layer 11
Similarly, a UV-curable ink is used.

Reference numeral 14 is a clear layer applied along the character 7 of "INVERTER", and this clear layer is also composed of a UV-curing type substantially transparent ink which is hardened by ultraviolet rays. Reference numeral 15 denotes a polyester film (auxiliary film), which covers the clear layer 14, that is, the ink layer 13 (character 7) so as to be connected.

The polyester film 15 reflects ultraviolet rays. Reference numeral 16 is a transparent resin film, and an adhesive (not shown) is applied to the entire back surface of this film, and a masking layer 17 is attached to this film by this adhesive. This masking layer 17 has "I
“NVERTER” is arranged so as to surround the character 7, and the height of the masking layer 17 and the first adhesive layer 1
The height of the masking layer 17 is set so that the height from 0 to the polyester film 15 is substantially the same.

In the transfer sheet 6 having such a structure, the second adhesive layer 11, the medium layer 12, the ink layer 1
3 and the clear layer 14 are both pre-cured with ultraviolet rays. When the transfer sheet 6 is attached to the exterior body 2, the release paper 9 is first peeled off (see the solid arrow in FIG. 3), and the peeled surface (first adhesive layer 10) side is placed on the exterior body 2.
Apply to. Then, the surface (transparent resin film 16) side of the transfer sheet 6 is rubbed with a jig 8 (one-dot chain line in FIG. 3).
At this time, the masking layer 17 and the polyester film 15
Since the transfer seed 6 is rubbed with the jig 8, the jig 8 covers the character 7 with the masking layer 17 and becomes a bridging state. And, "INVE
The pressure is applied substantially evenly to the character 7 "RTER". Therefore, it is unlikely that too much force is applied to only a part of the character 7 or conversely no force is applied, and the character 7 is reliably transferred to the exterior body 2.

After rubbing the transfer sheet 6 with the jig 8 in this manner, the transparent resin film 16 is peeled off. At this time, the masking layer 17 is peeled off together with the transparent resin film 16 while being stuck to the film 16. Here, a portion 18 of the transparent resin film 16, that is, a portion without the masking layer 17 adheres to the medium layer 12 and the release paper 9, and the masking layer 15 and the release paper 9 are simply overlapped. In FIG. 3, the transparent resin film 16, the medium layer 12, and the release paper 9 are not in a bonded state, but as shown in FIG. 2, a portion 18 without a masking layer is wide around the character 7. Therefore, this portion 18 is bonded to the release paper 9 and the medium layer 12.
Therefore, the transparent resin film 16 can be easily peeled off from the release paper 9.

In this way, the state in which the character 7 is applied to the exterior body 2 is as shown in FIGS. 4 and 5, and the exterior body 2 is shown.
The letters 7 covered with the clear layer 14 and the polyester film 15 are adhered. And this character 7 is about 200
Since the thickness A of the micron (0.2 mm) is provided, when the exterior body 2 is viewed obliquely from the front or the side, the character 7 appears to be lifted from the exterior body 2 and is high quality for customers. It can give a feeling.

Since the character 7 is covered with the polyester film 15 as described above, even if the exterior body 2 is installed outdoors and ultraviolet rays hit the exterior body 2, the ultraviolet rays are easily reflected by the polyester film 15. 2 adhesive layer 11,
Re-hardening of the medium layer 12, the ink layer 13, the clear layer 14, etc. is less likely to be promoted, and discoloration of the ink layer 13 is less likely to occur. Further, since the letters "I", "N", etc. are connected by the polyester film 15 (see FIG. 2), the strength of the polyester film 15 keeps the balance and spacing of the letters 7 in accordance with the dimensions, and the pattern is It is difficult to deform.

Further, since the polyester film 15 is relatively strong, when the transfer sheet 6 is peeled from the outer package 2, the polyester film 15 is likely to remain on the outer package 2 so that the peeling work can be facilitated. You can

In addition to the above-mentioned polyester film 15, there is a Tetron film or the like as a film that reflects ultraviolet rays.

[0018]

As described above, according to the present invention, a design is applied to the pressing surface of the film pressed against the exterior body, and the surface on the side opposite to the exterior body of this design is covered with an auxiliary film that reflects ultraviolet rays. As a result, it is possible to prevent the pattern, ink, etc. from changing over time due to ultraviolet rays. Further, the strength of the auxiliary film makes it difficult to deform the design.
