くは、４級以上である。The colorant in the present invention is a colorant that does not contain lead or chromium, such as phthalocyanine pigments and azo pigments. Various pigments are blended so as to not remarkably deteriorate. As a result, the dyeing fastness of artificial turf in the present invention can achieve the third or higher level of discoloration and discoloration after irradiation for 200 hours at 83 ° C. by the ultraviolet carbon arc lamp light test method of JIS L 0842. The discoloration is preferably quaternary or higher.
