Abstract
A napped artificial leather includes: a fiber-entangled body obtained by entangling ultrafine fibers; and an elastic polymer impregnated into the fiber-entangled body. The napped artificial leather has, on at least one side thereof, a napped surface formed by napping the ultrafine fibers. The ultrafine fibers contain 0.2 to 8 mass % of carbon black and 0.1 to 5 mass % of a chromatic pigment, and a total ratio of the carbon black and the chromatic pigment is 0.3 to 10 mass %. A content ratio of the elastic polymer is 0.1 to 15 mass % in the napped artificial leather. The elastic polymer is uncolored and the ultrafine fibers are undyed.
