摘要
A liquid pigment composition for master-coloring polyamides is described, which is comprised of a pigment and a pigment dispersant composed of a polymeric material selected from liquid polyesters and a liquid polyether esters, each having a hydroxyl value of 30 to 120 mg. KOH/g. The amount of the pigment dispersant is usually 30 to 3,000 parts by weight per 100 parts by weight of the pigment. A master-colored polyamide yarn also is described which contains, based on the weight of the yarn, 0.01 to 2% by weight of a pigment ingredient and up to 6% by weight of the above-mentioned pigment dispersant.
