Paper coating |
| abstract |
There is disclosed a paper coating composition comprising, in aqueous suspension, an adhesive and a treated paper coating pigment prepared by the following process:n (i) suspending a paper coating pigment in water to form a suspension containing at least 5% by weight of the pigment, the pH being adjusted, if necessary, to lie below 7.5; (ii) mixing with the suspension formed in step (i) a water-soluble organic compound having a plurality of primary and/or secondary amine groups and a number average molecular weight not greater than 1000; and (iii) at least partially dewatering the mixed suspension resulting from step (ii) to form a dewatered suspension of a treated paper coating pigment containing not more than about 30% by weight water; characterised in that the water soluble organic compound is added in step (ii) in an amount sufficient to decrease the 5 poise viscosity concentration of an aqueous suspension of the treated pigment relative to that obtained with the untreated pigment. The paper coating composition is particularly suited to the preparation of a coated paper which is to be printed on by a gravure technique. |
