Leather - Tests for colour fastness - Colour fastness to migration into polymeric materialstandard by International Organization for Standardization, 07/01/2022
standard by International Organization for Standardization, 07/01/2022
This document specifies a method for assessing the propensity of dyes and pigments to migrate from leather to a synthetic substrate by determining the transfer of colour from the leather to white polymeric material in contact with it.
