Cigarette paper comprising flaky filler

A cigarette, comprising a tobacco rod and a cigarette paper wrapping the tobacco rod, whereby the cigarette paper is a cigarette paper, which contains pulp fibers and filler particles , whereby at least 20% of the filler particles, by mass or by particle number, have a flaked shape,

• wherein the flaked filler particles have a length l, a width b and a thickness d, which correspond to the respective maximum extension in three mutually orthogonal spatial directions, whereby the length l as well as the width b are at least twice as large as the thickness d, wherein the mass-specific median value d50 of the particle size distribution measured according to ISO 13317-3 is between 0.2 μm and 4.0 μm, and wherein the flaked particles are formed by calcium carbonate;
• and
• wherein the cigarette paper has an air permeability of x CORESTA Units and a diffusion capacity Dx* for CO2, and whereby Dx*·√{square root over (50)}/√{square root over (x)}≧1.80 cm/s holds.
