により転写箔３を加熱する。 Conventionally, as a method of bringing a transfer foil into close contact with these uneven products, a method has been used in which the transfer foil is heated and softened, and then the transfer foil is molded and brought into close contact with the uneven surface of the product using gas or liquid. In addition, in order to prevent air from being drawn in when the product surface and transfer foil come into close contact, the product, transfer foil, and a heater for heating and softening the transfer foil are placed in a vacuum mold, and the transfer foil and product are placed in a vacuum mold. Currently, methods are being used to bring the materials into close contact with each other.
An example of a currently used type of device for this purpose is shown in FIG. A moldable transfer foil 3 is stretched between the upper mold 1 and the lower mold 2, the mold is closed with a mold clamping cylinder 8, and a heating heater 4 is installed inside the upper mold 1.
The transfer foil 3 is heated.

密着させる方法が用いられている。 At this time, the molded product 5 is placed on the product stand 6, the push-up cylinder 7 is lowered, and the transfer foil 3 and the product 5 are not in contact with each other, and the transfer foils in the upper mold 1 and the lower mold The space around the product is evacuated, and when the transfer foil 3 is softened by the heating heater 4, the pushing-up cylinder 7 is operated, and the transfer foil 3 and the product 5 are
After the transfer foil 3 and the molded product are brought into contact with or pushed up further as necessary to stretch the transfer foil, air is introduced into the upper mold 1 to return it to atmospheric pressure, and further pressurized gas is introduced as necessary. A method is used in which the transfer foil is molded and the product is brought into close contact with the transfer foil.
従来この転写方法に用いる転写箔ベースフイル
ムとしては熱成形性の優れるフイルムとしてPS、
ABS、PVC等の材質が用いられている。 Conventionally, the transfer foil base film used in this transfer method is PS, which has excellent thermoformability.
Materials such as ABS and PVC are used.

ムが軟化しすぎて自重により垂れ下つて成形が不
可能となる問題があつた。 These films have a wide range of moldability, and have the advantage that even if the heating temperature of the film changes slightly, the state of the softened film does not change much. There was a problem that the material became too soft and sagged under its own weight, making it impossible to mold it.

ルムの成形ができなくなり、フイルムが被転写体
に密着しない部分が生じ転写が不可能となる。 In addition, even if the film does not sag, it is still too soft, so if there is a part of the molded product that is being transferred that has significant changes in surface irregularities, such as some steps or holes, the film will stretch. It was easy to cut and often had holes. In this case, if a hole is formed in the film, the pressure difference between the front and back sides of the film becomes small, making it impossible to shape the film using compressed air or vacuum force, and there are parts of the film that do not come into close contact with the object to be transferred, making transfer impossible.

ロツキングを起こす。特にPS、PVCフイルムは
これら低温熱活性の接着剤と接着しやすい性質が
あり特にブロツキングしやすい問題があつた。 In order to enable transfer in a temperature range where the film is suitable for molding, we lower the film heating temperature and use a resin (methacrylic acid ester polymer or copolymer) that is thermally active at low temperatures as an adhesive for the transfer foil. When using resins such as polymers, acrylic ester polymers or copolymers, vinyl chloride polymers or copolymers, etc., the film and low-temperature heat-activated adhesive will stick together when it is rolled up during storage. cause blocking in order to do so. In particular, PS and PVC films have a tendency to adhere easily to these low-temperature heat-activated adhesives, and are particularly susceptible to blocking.
この問題を解決する為には、フイルムの印刷さ

ングし巻取とし、接着剤とフイルムとが直接接着
しない構成とする方法がある。 In order to solve this problem, there is a method of coating the back of the printed surface of the film with an anti-blocking layer and winding the film so that the adhesive and the film do not adhere directly.

使用が難しかつた。 The anti-blocking layer must be made of a resin-based material that does not have adhesion to heat-activated adhesives, and for this purpose, a two-component reaction-curing coating agent or a resin-based material that softens when heated is usually used. However, coating, drying and curing techniques are difficult to apply these coating agents to thermoformable sheets, and they may also impede the formability of the film, making them difficult to use in practice.

ある。 The present invention has good moldability, and even if the heating temperature of the transfer foil is raised, there is little sagging of the transfer foil, resulting in stable molding, and the occurrence of holes during molding is small, as well as preventing blocking during storage of the transfer foil. This relates to the transfer foil that can be produced. Namely, polystyrene (PS), acrylonitrile-butadiene-styrene copolymer (ABS), polyvinyl chloride (PVC),
A base sheet is created by laminating a polyolefin resin on the back side of a thermoformable sheet made of polyacrylonitrile (AN), acrylonitrile-styrene copolymer (AS), etc., and a release layer and a pattern layer are placed on the thermoformable surface of this base sheet. and at least three adhesive layers mainly composed of a methacrylic acid ester polymer or copolymer, an acrylic acid ester polymer or copolymer, a vinyl chloride polymer or copolymer, or a mixture thereof. This is a transfer foil formed sequentially.

度が高く成形性シートとしては不適当である。 The thermoformable sheet 9 of the present invention is a sheet that can be softened and plasticized and molded by heating with a heating plate or the like that has been subjected to infrared rays or hot air releasability treatment, and has a thickness of 20 to 20 mm.
Although it is possible to use a sheet of 500μ, it is desirable that the sheet softens and plasticizes at as low a temperature as possible, and that the plasticized state does not easily change even if the heating temperature changes slightly. Most preferred are nitrile-butadiene-styrene copolymer resin (ABS), polyvinyl chloride, polyacrylonitrile, and acrylonitrile-styrene copolymer. Other general-purpose sheets include polyolefin, polyamide, polycarbonate, etc., but these have a narrow moldability range and a high softening temperature, making them unsuitable as moldable sheets.

る役割を果たす。 The polyolefin resin 10 does not have adhesive properties to the adhesives used for the transfer foil, and even if it is pressed against these adhesives for a long period of time as a roll, it will not adhere.
Acts as an anti-blocking agent. In addition, when heating and softening the transfer foil, PS of the thermoformable sheet,
For ABS and PVC, when the sheet temperature reaches 70 to 80℃,
Since the softening temperature range is wide, it stretches and sag due to its own weight, impairing moldability. By laminating the polyolefin resin 10 on the back side of the thermoformable sheet, the property of the polyolefin resin is that it will not elongate due to softening unless it reaches a temperature close to its softening temperature, and it serves to hold the laminated thermoformable sheet and prevent it from sagging. fulfill.

を保持することができる。 The thicker the polyolefin resin 10 is, the less the thermoformed sheet will sag, but the moldability will deteriorate unless the polyolefin resin 10 is heated until it is sufficiently softened and can be molded. Therefore, the thickness is preferably 200μ or less, preferably 100μ or less. especially
When the thickness is 100 μm to 20 μm, even if the heating temperature is within a range where the polyolefin resin 10 is not sufficiently softened, the pressure difference between the front and back sides of the transfer foil during molding is 1 to 3 μm.
Kg/cm 2 , the transfer foil can be perfectly molded, and the molding temperature will not rise or the moldability will deteriorate due to the bonding with polyolefin resin 10, which has a high softening point. It is possible to maintain the properties that the adhesive sheet 9 is hard to hang down and hard to form holes during molding.

さを厚くし、逆の場合は薄くて良い。 When the thickness of the polyolefin resin 10 is 10μ or less, the anti-blocking effect is sufficient, but
The effect of preventing the thermoformable sheet 9 from sagging is reduced. The thickness of the polyolefin resin 10 is determined by the size of the transfer foil and the heating conditions during molding. That is, if the area covered with the transfer foil is large and the heating temperature is high, the thickness of the polyolefin resin 10 may be increased, and in the opposite case, it may be made thin.

好しい。 As for the polyolefin resin 10 used, it is preferable to use a resin with a higher softening point as the molding temperature is higher, and if a resin that is particularly prone to blocking is used in the adhesive layer of the transfer foil, polymethylpentene resin is particularly effective in preventing blocking. It has excellent effects and is the most preferred.

Methacrylic esters, acrylic esters, and vinyl chloride resins have almost no adhesive strength to polyolefin resins, and even if these adhesives and the polyolefin layer are in contact for a long time during winding, they will not adhere or block. do not have. For this purpose, it is better not to oxidize the surface of the polyolefin resin by corona discharge or the like, or to form the polyolefin resin into a film at high temperatures.

写を行う。 As a method of heating the transfer foil, the transfer foil is heated to 100 to 200° C. using infrared rays, heated air, a heating plate subjected to mold release treatment, etc. to soften the transfer foil. After that, a vacuum forming method is used in which the pressure is reduced between the transfer foil and the molded product, and the transfer foil is tightly molded to the molded product.The transfer foil is then molded into a molded product using a vacuum forming method that produces 1 to 10 kg/cm 2 from the top of the transfer foil.
The pressure forming method uses pressurized gas to compress the transfer foil and press it onto the object to be transferred. After reducing the pressure on the top and bottom of the transfer foil, the upper part of the transfer foil is transferred by applying higher pressure than the space below where the object is located. Transfer is performed by molding the foil using a vacuum-pressure method in which the foil is suction-pressed and pressed onto the object to be transferred.

However, since the polyolefin resin on the back side does not melt and stick to the heating element and cannot be removed,
Stable transfer processing is possible even if the heating temperature of the transfer foil is set high.
