Size press coating method |
摘要 |
The invention provides an improved method of coating mediumweight and heavyweight papers in a size press by applying a paper coating composition comprising a binder wherein the binder comprises a stable aqueous dispersion comprising a water insoluble component and a water soluble component such that the water insoluble component comprises coalescable polymer particles which have a Tg less than 55 DEG C. and a majority of which have a particle size less than 1 micron; and the water soluble component comprises a water soluble polymer capable of inhibiting coalescence of said polymer particles, or a water soluble polymer and a component capable of inhibiting coalescence of said polymer particles; and wherein said water insoluble component comprises greater that 3% and less than 75% by weight of the binder solids and said water soluble component comprises greater than 25% and less than about 97% of said solids.
