ABSTRACT OF THE DISCLOSURE A process for the dyeing of polymers of ethylene is disclosed. The process involves contacting articles of the polymer with an aqueous dyebath containing a basic dye in a concentration of at least 0.4 g/l and at a pH of 5.0-7.5. The temperature of the aqueous dyebath is at least 90°C. The article is maintained in contact with the dyebath for at least 20 seconds. The polymer of ethylene is a blend of 80-99 parts of a homopolymer of ethylene or copolymer of ethylene and at least one C4 - C10 higher alpha-olefin with 1-20 parts of a direct or graft copolymer of an alpha-olefin having carboxylic acid, carboxylic acid anhydride, ionomeric or -OH groups. Dyed polymers of ethylene are obtained.
