Abstract

A synthetic leather comprising a substrate, a skin layer that is disposed on one main surface of the substrate, and an anti-stain layer that is disposed to cover the skin layer. The anti-stain layer contains a base resin that comprises silicon and a unit derived from a compound that has a urethane bond. In the anti-stain layer, a fluorine atom/silicon atom atomic ratio, which is a proportion of a fluorine atom to the silicon atom, is 0.01 or less. A first color difference ΔE1* between before and after a stain adhesion test performed on the synthetic leather rubbed under a specific condition is 5 or less.
