<p>Mineral filler comprises talc particles with a diameter within a grain size spectrum, where 20% of the talc particles exhibit a maximum diameter d-20% and 50% of the talc particles exhibit a maximum diameter d-50%, where a steepness factor of the particle size distribution, which is defined by the quotient d-50% /d-20%, has a maximum value of 2.3, preferably 2.2.</p> |
