インキは、その印刷方法に合った印刷用インキ、筆記用
インキが主である。Conventional marking methods for plastic lenses are generally letterpress, lithographic, and intaglio printing. The inks used during printing are mainly printing inks and writing inks that match the printing method.
（発明が解決しようとする問題点〕
しかし、現在使用されている一般的な、印刷インキ、筆

が剥れたりする問題点を宵していた。(Problem to be solved by the invention) However, with the general printing inks and writing inks currently in use, marking is carried out on plastic lenses whose surface conditions have a contact angle of 70° or more with respect to water. In this case, there were problems in that the ink was repelled and the ink easily peeled off after printing.

チックレンズのマーキング方法を提供することにある。Therefore, the present invention aims to solve these problems.
The purpose of this is to be able to mark plastic lenses with water contact angles of 70@ or more and surface conditions without repelling them, to prevent them from peeling off during post-processing, and to make markings possible after processing. (If this happens, you can easily remove the markings with ethanol.@Our objective is to provide a method for marking plastic lenses for mirrors.

。For example, when marking the distance and near vision areas on a progressive lens that has been treated with water and oil repellency using letterpress printing or intaglio printing, printing ink containing a fluorine-based surfactant can be used to make the lenses repellent. It is possible to print without
It has become possible to easily remove markings with ethanol without peeling off even after post-processing such as beading.

。The contact angle of the plastic lens for marking with water is preferably in the range of 70'' to 140°. If the contact angle with water is 70° or less, there is no need to use a printing ink containing at least a fluorosurfactant (
Further, if the angle is 140° or more, even if the ink of the present invention is used, it will repel during printing and marking will not be possible.
以下、実施例により本発明の詳細な説明するが、本発明
