A colored porous polytetrafluoroethylene material prepared by impregnating a colorant in a porous polytetrafluoroethylene material having a fine fiber structure consisting of fibers and nodes connected to one another through the fibers, and then heating the porous material at a temperature of at least a melting point of the porous material has porosity inherently possessed by the porous material and no distortion o~ a coloced line.
La présente invention vise un matériau à base de polytétrafluoroéthylène, poreux et coloré, produit par imprégnation d'un colorant dans ce matériau à structure fibreuse fine constituée de fibres et de noeuds interreliés, puis par chauffage du matériau à une température au moins égale à son point de fusion.
