    摘要： Modified high-molecular weight polyamides having chemically incorporated therein 0.01 to 10 percent by weight of a basic monoepoxy compound of the general formula: WHEREIN R1 and R2, which may be different or not, each represents a C1-C20 aliphatic radical selected from the group consisting of an unsubstituted radical and a substituted radical containing functional groups inert to polyamides, a cycloalkyl radical, a benzyl radical, or R1 and R2, together with the nitrogen atom to which they are attached, form a heterocyclic ring; are provided which polyamides show an improved affinity for acid dyes.
