Abstract (en)

[origin: EP0648894A1] Paperboard of the kind used for making business cards, invitation cards, menu cards, report covers and the like is surface enhanced by the application of a low coatweight (typically 1 to 5 g m <-><2>) coating of (a) a pigment having an oil absorbency of at least about 80 g/ 100 g pigment, and (b) a binder. The pigment is preferably an aluminosilicate, a symthetic amorphous silica, a calciumed kaolin, or an acid-washed montmorillonite clay, and the binder is preferably a styrene-butadiene latex. The coating reduces set-off and enhances print density after offset printing whilst not substantially affecting the aesthetic character of the product compared with conventional uncoated paperboard.
