Abstract:
A fiber comprising a polymer matrix component in which particle scattering colorant particles are dispersed, wherein said particle scattering colorant particles comprise a metallic conductor selected from the group consisting of gold, platinum, copper, aluminum, lead, palladium, silver, rhodium, osmium, iridium, and alloys thereof; the particle scattering colorant particles have an average diameter in the smallest dimension of less than about 0.02 microns; the polymer matrix component is substantially non-absorbing in the visible region of the spectrum; and the particle scattering colorant has a minimum in the transmitted light intensity ratio in the 400 to 700 nm range that is shifted at least by 10 nm compared with that obtained for the same metallic conductor having an average particle size above about 20 microns.
