A golf ball of a first color is dyed to a second color with an anionic or nonionic disperse dye. Either or both of a pigmented coating layer or an optional clear coating layer on the pigmented coating layer comprises a member selected from the group consisting of polyurethanes, polyureas, polyamides, and combinations thereof, which can be dyed by the anionic or nonionic disperse dye.

Method for dyeing golf balls and dyed golf balls

A coloring system includes an assembly for retaining articles to be colored and an actuator for moving the assembly. The assembly can be translated horizontally, raised and lowered and rotated by the actuator. The coloring system may include a fluid control system that allows gas to be removed from a container of the assembly while the container is immersed in a liquid coloring agent.

Assembly for coloring articles and method of coloring

A polyurethane is dyed with an aqueous solution of an acid dye compound, a quaternary ammonium compound selected from soluble tetrabutylammonium compounds and tetrahexylammonium compounds, and, optionally, an water-soluble organic solvent.

Acid dyeing of polyurethane materials

A method and apparatus for coloring an article includes fastening an article to a container which at least partially encloses the article. The article fastens to the container in a fixed position. A portion of the container is inserted into a liquid by an actuator. The liquid enters the container through an open end. An air pocket is created in the container when it is inserted into the liquid. A first portion of the article is contained within the air pocket and a second portion of the article is dipped into the liquid and thereby is colored from a dye in the liquid. The actuator also removes the container and the article from the liquid. The process can be repeated with the article in an inverted position and with another liquid to color another portion of the article a second color.
