本発明は絵付成型物の製造法に関するものであ

麗な絵付成型物を高に作業効率で得ることにあ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a painted molded article, and its purpose is to obtain a beautiful painted molded article with excellent surface strength with high work efficiency.
従来、金属成型物に絵付する方法として次の２
方法が考えられている。即ち(1)金属材料を適宜な
形に成型した後、樹脂層を設け絵付を施す方法。
(2)金属材料表面に樹脂層を設け絵付を施す方法。
しかしこれらの方法はいずれも欠点を有してい
た。即ち(1)の方法では成型された物品に樹脂層を
設け絵付を施すため、成型物の形状に応じて樹脂
層を設け絵付を行う必要があるから作業効率が低
下し、さらに細かい凹凸部分、谷の深い部分には
絵付を施すことができないという欠点が生じる。
(2)の方法では成型の際、樹脂層にクラツクが生じ
るのを防ぐため可塑性樹脂を用いて樹脂層を形成
しなければならず、このため表面強度の弱い製品
しか得ることができない、等の欠点があつた。 Traditionally, there are two methods for painting metal moldings:
A method is being considered. Namely, (1) a method in which a metal material is molded into an appropriate shape, then a resin layer is applied and a decoration is applied.
(2) A method in which a resin layer is placed on the surface of a metal material and a painting is applied.
However, all of these methods had drawbacks. In other words, in method (1), since a resin layer is applied to the molded article and the decoration is applied, it is necessary to apply the resin layer and the decoration according to the shape of the molded object, which reduces work efficiency, and furthermore, it is necessary to apply the resin layer and the decoration to the molded article. The drawback is that it is not possible to apply paintings to the deep parts of the valley.
In method (2), the resin layer must be formed using plastic resin in order to prevent cracks from occurring in the resin layer during molding, and as a result, only products with weak surface strength can be obtained. There were flaws.
本発明者はこれら従来法の欠点に鑑み種々研究
した結果、表面強度の優れた美麗な絵付成型物を

る。 As a result of various studies in view of these drawbacks of conventional methods, the present inventor has invented and completed a method for manufacturing beautiful painted molded products with excellent surface strength with high work efficiency. That is, in the present invention, a resin layer 2 made of a thermosetting resin having a pencil hardness of 3H or higher in a completely cured state is formed on the surface of a metal plate 1, and after heating at a temperature at which the resin is semi-cured, the thermal transfer property is The surface of the resin layer 2 is painted using an ink containing the dye 3, and then a metal plate is molded into an appropriate shape, after which the heat-transferable dye 3 is transferred into the resin layer 2 and the surface of the resin layer 2 is painted. This is a method for producing a painted molded article, which is characterized by heating at a temperature at which the resin completely hardens.

板１表面より剥離しない状態を意味する。前記の
樹脂であれば80℃〜220℃で30分〜２分間加熱す
ると半硬化状態にせしめることができる。 The present invention will be explained in more detail below. First, a resin such as a thermosetting resin, an epoxy resin, or an acrylic-melamine resin, which has a hardness of 3H or more in a pencil hardness in a completely cured state, is applied to the surface of the metal plate 1 to be molded by a roll coating method, a flow coating method, or the like. The resin layer 2 is formed by applying by spraying, dipping, etc. (see FIG. 1). The reason why the thermosetting resin is selected is that these resins have excellent strength in the cured state and are completely cured at the temperature at which the heat-transferable dye described later is thermally transferred. Next, the resin is heated to semi-cure. Here, "semi-cured" means a state in which the resin does not interfere with painting and does not easily peel off from the surface of the metal plate 1 upon contact. The above-mentioned resin can be heated to a semi-cured state by heating at 80°C to 220°C for 30 minutes to 2 minutes.
次に前記半硬化状態の樹脂層２の表面に熱移行

絵付を施した後、プレス成型等により金属板を
適宜な形に成型する（第３図参照）。成型後再び
加熱する。この場合の加熱は前記熱移行性染料３
を前記樹脂層２内に移行せしめること及び樹脂を
完全硬化せしめることの２つを目的とするもので

内に移行し、樹脂は完全に硬化する（第４図参
照）。 Next, the surface of the semi-cured resin layer 2 is painted using an ink containing a heat-transferable dye 3.
Examples of the dyes used include disperse dyes, cationic dyes, and mordant dyes. The decoration is done by transfer printing, screen printing, etc. Hand-painted illustrations are also possible. (See Fig. 2) After the decoration is applied, the metal plate is formed into an appropriate shape by press molding or the like (see Fig. 3). After molding, heat again. In this case, heating is performed using the heat transferable dye 3.
The two purposes are to transfer the resin into the resin layer 2 and to completely cure the resin. For the above dyes and resins, 30% at 150℃ to 220℃
By heating for 3 minutes to 3 minutes, the dye is applied to the resin layer 2.
The resin is completely cured (see Figure 4).
本発明は以上のような絵付成型物の製造法であ

に際して実用価値の高い製造法である。 Since the present invention is a method for manufacturing a decorated molded article as described above, a decorated molded article having excellent surface strength and a beautiful pattern even in small recesses can be obtained with high work efficiency. Therefore, it is a manufacturing method of high practical value when producing molded products with engraved designs on the surface or painted molded products such as cosmetic containers.
