ABSTRACT:
A colored, porous fluorocarbon material is provided wherein a porous layer of a colored dyeing-site resin is formed on all surfaces of the fluorocarbon material. This new material is made by a process whereby an auxiliary solvent which does not readily dissolve a dyeing-site resin, if at all, is added to a solution of the dyeing-site resin in a main solvent, and this is coated onto the surfaces of the fluorocarbon material and dried. The material may be dyed by adding dyestuff to the aforesaid solution or it may be dyed after coating and drying. The coated fluorocarbon material can be stretched.
