Description

( Reference Example 1)
In Example 1, an adhesive label for thermal recording was prepared in the same manner as in Example 1 except that the sealing layer solution was not applied.

Next, with respect to the sealing layer solution, release paper, and heat-sensitive recording adhesive label in Examples 1 to 22, Reference Example 1, and Comparative Examples 2 to 6, the coating property of the sealing layer solution is as follows. , Light transmission and release properties were evaluated. The results are shown in Table 2.

表１の結果から、実施例１〜８と参考例１、比較例２〜３を対比した結果から、目止め層が水溶性樹脂とアセチレングリコール化合物を含有することにより、塗工性及び光透過性が良好となることが分かった。
実施例１〜１９と参考例１、比較例２〜５を対比した結果から、目止め層と剥離層の間に中間層を設けることにより、更に剥離性が良好となることが分かった。

From the results of Table 1, Examples 1 to 8, Reference Example 1 and Comparative Examples 2 to 3 were compared, and the sealing layer contained a water-soluble resin and an acetylene glycol compound, thereby providing coating properties and light transmission. It was found that the properties were good.
From the results of comparing Examples 1 to 19, Reference Example 1 and Comparative Examples 2 to 5, it was found that the peelability was further improved by providing an intermediate layer between the sealing layer and the release layer.
