のパターンを形成する方法である。 The inventor of the present invention previously developed a transfer printing method using a transfer pad, in which patterns such as letters and symbols are dyed and formed on the surface of a key cap base material using a transfer sheet used for painting on various articles. Through his invention, he succeeded in obtaining a key cap with letters and symbols that had excellent wear resistance (patent application filed in 1983).
No. 38333). In this method, a transfer sheet is formed by forming a pattern layer of letters, symbols, etc. on a base sheet such as paper or plastic film using ink containing a heat-transferable dye, and is fixed with a fixing jig. The pattern layer is placed on a plurality of key cap base materials so that it is in contact with the transfer surface of the key cap base material, and then a transfer pad having a plurality of elastic protrusions each having a curved tip is used. The transferring surface of the key cap base material and the pattern layer are brought into close contact by pressing from the base sheet side of the transfer sheet, and then heat treatment is performed while the transfer surface of the key cap base material and the pattern layer are kept in close contact with each other. In this way, the heat-transferable dye in the pattern layer is thermally transferred to dye the transfer surface of the key cap base material with a desired pattern of characters, symbols, etc., and then the base sheet is removed. In this method, patterns such as letters and symbols are formed on the surface of a plurality of keycap base materials.

る。 However, in this method, the transfer sheet described above,
That is, it has been found that it may be inappropriate to use a transfer sheet, which is formed by forming a pattern layer of characters, symbols, etc. on a base sheet using an ink containing a heat-transferable dye, as it is. That is, since the top surface of the key cap base material usually has a concave curved surface in order to improve the feeling of contact with the fingertips, the key cap base material is This is because it is difficult to provide clear characters, symbols, etc. In other words, when the transfer sheet is placed on the key cap base material and then pressed using a transfer button, the transfer sheet is brought into close contact with the concave curved surface of the top surface of the key cap base material, causing local tension. This is because the transfer sheet may be torn and the pattern layer may be damaged, resulting in misalignment and misregistration.

全く起こさないものである。 Since the transfer sheet for curved surface painting according to the present invention has the above-described structure, it has the following effects. That is, the transfer sheet according to the present invention,
When applied to a method of manufacturing key caps by transfer printing using a transfer pad, when the transfer sheet placed on the key cap base material is pressed by the transfer pad, the transfer sheet is attached to the transfer surface of the key cap base material. Even if the transfer sheet is brought into close contact with the transfer sheet along the concave curved surface and tension is applied locally, the tension is dispersed and relieved by the perforations. Therefore, the transfer sheet is completely free from misalignment and misregistration.
従つて本考案に係る湾曲面絵付用転写シートは
実用価値の極めて高いものである。 Therefore, the transfer sheet for painting curved surfaces according to the present invention has extremely high practical value.
