The present invention relates to an ionic light fastness enhancer and to dyeing using the same.

Polyamide fibers are being used in a wide range of applications, from interior areas such as curtains to outdoor clothing such as climbing gear and sporting goods. Since the fibers used in these fields are exposed to sunlight for a long time, the color fading of the fibers progresses over time, thereby deteriorating the aesthetic characteristics of the fibers, so that a high light fastness is required. Accordingly, it is necessary to secure a technique for increasing the light fastness of polyamide fibers.

Currently, the most common method for increasing the light fastness of polyamide fibers is to use a light fastness enhancer for polyester fibers. However, since polyester-based fibers and polyamide-based fibers are fundamentally different from each other in their mechanism of seizing, application of a light fastness improving agent for polyester fibers to polyamide-based fibers is hardly expected as a fundamental solution.
