Abstract (en)

[origin: WO2016016340A1] The invention relates to a paper comprising: a fibrous substrate; a precoat including a binder and a mixture of lamellar filler(s) having a form factor of at least 15 and of finer filler(s) having a particle size, at a concentration of 80% by weight, of less than 2 μm (measured using the SediGraph technique according to ISO 13317-3); and at least one coating layer applied to the precoat, said paper having a water vapour permeability of at most 150 g/m2/24h and preferably less than 100g /m2/24h, measured according to ASTM F 1249 under so-called tropical conditions of 38°C and 90% relative humidity.
