Manufacturing method of colored plastic lens |
| abstract |
PROBLEM TO BE SOLVED: To provide a dyeing bath for producing a colored plastic lens with high stability, remarkably reduce complicated and uneconomical work in the dyeing process, and produce a stable colored plastic lens. To provide. SOLUTION: In a method for producing a colored plastic lens by immersing a base lens in an aqueous dyeing bath in which a dye is dispersed, the dyeing bath contains a naphthalenesulfonic acid formaldehyde condensate salt and has a hydrogen ion concentration (pH). 2 By using the dyeing bath adjusted to 6.5, a colored plastic lens with stable dyeing concentration and hue can be manufactured for a long period of time. |
