PAPER COATING COMPOSITIONS COMPRISING A POLYMER DISPERSION FROM ROOM TEMPERATURE LIQUID AND GASEOUS MONOMERS

摘要

Paper coating compositions comprise inorganic pigments and an aqueous polymeric dispersion comprising dispersed polymeric particles. The polymers are obtainable by polymerization of a first monomer that is liquid at room temperature, has a boiling point of at least 50°C and a glass transition temperature of at least 20°C as homopolymer, and a second monomer that is gaseous at room temperature, has a boiling point of below 0°C and a glass transition temperature of below -30°C as homopolymer. The dispersed polymeric particles have an average size of below 150 nm and a glass transition temperature in the range from -10 to +30°C.
