The mass coloration of nylon‐1010 with a melting‐reactive dye, an economically favorable and environmentally friendly method of coloration, is described. Perylene‐3,4,9,10‐tetracarboxylic acid dianhydride (PTAD) was used as a melting‐reactive dye for nylon‐1010, and it showed high thermal stability. A chain‐extending reaction was confirmed by an ultraviolet–visible spectroscopic analysis. The effect of the proportion of added PTAD on the intrinsic viscosity of the polymer was studied, and increased amounts resulted in increased intrinsic viscosity. The light fastness of the colored fibers was found to be 4. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 83: 2164–2167, 2002
