Beschreibung
Zusammenfassung:	The invention relates to a composition with an economical aqueous form, permitting the production of anti-slip supports with no risk of sticking of the sheets, of use in a paper machine, characterised in having anti-slip properties which do not alter over a wide temperature range (- 40 DEG C to 220 DEG C). The composition substantially comprises 15 to 85 parts of a thermoplastic with a Tg less than 50 DEG C and 85 to 15 parts of diatomaceous fossils. L' invention concerne une composition sous forme aqueuse très économique, permettant la fabrication de supports antiglisse sans risque de collage entre les feuilles, utilisable sur machine à papier, et présentant la caractéristique d'avoir des propriétés antiglisse qui ne varient pas dans une large gamme de température (- 40°C à 220°C). Cette composition comprend principalement de 15 à 85 parts d'un thermoplastique ayant une Tg inférieure à 50°C et de 85 à 15 parts de diatomées fossiles.
