A value of 0 allows the design (two colors) to be clearly printed on the ceramic product surface as follows. Mount 102
The transfer sheet 100 is pressed against the heated ceramic product with the side facing upward. At this time, the pigment layers 103 and 104 are plasticized by heat and are transferred to and adhered to the ceramic product. The ceramic product is fired at a high temperature (about 600 ° C.), and the pigment layers 103 and 104 are baked on the ceramic surface.

とができた。When the transfer sheet 50 is used, the insulator surface 20
The pigment layers 7 and 8 can be transferred to the insulator surface 200 without any omission without processing (polishing or cutting) or glazing, and as shown in Table 2, a yellow line is formed on the insulator surface 200. 23 and the red numeral 24 could be printed clearly without any omission.

付けることができた。The use of the transfer sheet 51 prevents the pigment layers 7 and 8 from being lost without processing (polishing or cutting) or applying glaze to the insulator surface 200.
0, and as shown in Table 2, the yellow line 23 and the red numeral 24 were almost completely baked on the insulator surface 200 without any omission.
【００３８】これは、以下の理由によるものと思われ

料層７、８を等径部分２２０に転写する際、剥離層６の
熱可塑性樹脂が流動化（約８０℃の転写温度による）し
て上質紙５と剥離層６との間の接合強度が低下し、接着
層９が碍子表面２００に接着し、上質紙５を剥ぎ取るこ
とにより、顔料層７、８が碍子表面２００に鮮明に転写
される。This seems to be due to the following reasons. In the transfer sheet 50 provided with the release layer 6, when the transfer sheet 50 is pressed against the insulator 2 with the high-quality paper 5 facing upward and the pigment layers 7 and 8 are transferred to the equal-diameter portion 220, the heat of the release layer 6 The plastic resin is fluidized (depending on the transfer temperature of about 80 ° C.), and the bonding strength between the high-quality paper 5 and the release layer 6 decreases, and the adhesive layer 9 adheres to the insulator surface 200, and the high-quality paper 5 is peeled off. As a result, the pigment layers 7 and 8 are clearly transferred to the insulator surface 200.
【００３９】又、剥離層６を設けない転写シート５１で
は、上質紙５を上側にして転写シート５０を絶縁碍子２
に圧接して、顔料層７、８を等径部分２２０に転写する
際、顔料層７、８の熱可塑性樹脂が流動化（約８０℃の
転写温度による）して上質紙５と顔料層７、８間の接合
強度が低下し、接着層９が碍子表面２００に接着し、上
質紙５を剥ぎ取ることにより、顔料層７、８が碍子表面
２００に転写される。In the transfer sheet 51 having no release layer 6, the transfer sheet 50 is placed on the insulator 2 with the high quality paper 5 facing upward.
When the pigment layers 7 and 8 are transferred to the equal-diameter portion 220 by pressing against the same, the thermoplastic resin of the pigment layers 7 and 8 is fluidized (at a transfer temperature of about 80 ° C.), and the high quality paper 5 and the pigment layer 7 , 8 is reduced, the adhesive layer 9 adheres to the insulator surface 200, and the high quality paper 5 is peeled off, so that the pigment layers 7, 8 are transferred to the insulator surface 200.
【００４０】どちらの場合も、顔料層７、８は、接着層

凸部が存在していても、欠落無く顔料層７、８がセラミ

ると、黄色のライン２３や赤色の数字２４が欠落無く碍
子表面２００に焼き付けられる。In both cases, since the pigment layers 7 and 8 are adhered to the adhesive layer 9 and reinforced, even if the insulator surface 200 has irregularities, the pigment layers 7 and 8 can be made of ceramics without loss. Transferred to the surface. Then, when baked at the baking temperature, the yellow line 23 and the red numeral 24 are baked on the insulator surface 200 without missing.
