Polyurethane polymers can be dyed in different ways by means of colouring pulps or compatible inks.
Dyeing is performed in bulk by adding the colouring agent to the polyol, or by adding it during the mixing phase of the polyol with the prepolymer.
The reaction rate, when the colouring agent is added to the polyol, varies depending on the used quantity.
