USO EN UNA PINTURA DE CARBONATO DE CALCIO QUE COMPRENDE QUE DICHO CARBONATO ESTA MOLIDO EN SECO EN PRESENCIA DE UN AGENTE DE AYUDA A LA MOLIENDA, EN QUE EL AGENTE DE MOLIENDA ES UN COPOLIMERO CONSTITUIDO POR MONOMERO ANIONICO ELEGIDO ENTRE ACIDO ACRI

摘要

The invention resides in the use in a paint of a calcium carbonate characterised in that it is obtained by dry-grinding, firstly, and in that it is dry-ground in the presence of a grinding aid agent which is a copolymer of (meth)acrylic acid with a monomer containing an alcoxy or hydroxy polyalkyleneglycol group, secondly.
