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.

A napped artificial leather, comprising:
- a fiber-entangled body obtained by entangling ultrafine fibers;
- and
- an elastic polymer impregnated into the fiber-entangled body,
- the napped artificial leather having, on at least one side thereof, a napped surface formed by napping the ultrafine fibers,
- wherein the ultrafine fibers are fibers of at least one thermoelastic resin selected from the group consisting of an aromatic polyester, an aliphatic polyester, a nylon and a polyolefin,
- the ultrafine fibers comprise 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 %,
