摘要:
A method for the preparation of a coated substrate is provided, comprising the steps of providing a substrate; applying on at least one side of said substrate a first coating layer of a first aqueous composition comprising porous anionic pigment particles having a BET surface area of above 40 m2/g and a binder and applying on said first coating layer, a second coating layer of a second, aqueous composition comprising cationic colloidal silica or silicate based particles and polyalkylene glycol. It has been found that a substrate coated with the combination of the first coating layer and the second coating layer provides a suitable substrate for high-quality and fast-drying inkjet printouts.

A coating composition may include kaolin having a shape factor less than about 70 and calcium carbonate, wherein less than about 90% by weight and greater than about 60% by weight of particles of the calcium carbonate have an equivalent spherical diameter (esd) less than 2 microns. The coating composition may include a thickener present in an amount ranging from about 0.1% to about 0.9% by active dry weight of the composition. A coating composition may include kaolin having a shape factor less than about 70 and calcium carbonate having a mean particle size (d50) of at least about 2.4 microns and a steepness factor of at least about 30. The coating composition may be a paper basecoat composition or a paperboard basecoat composition. A paper or paperboard product may include the coating composition on at least one surface of the paper product or paperboard product.

摘要:
The invention provides a method for the application of a treatment agent to a substrate, the method comprising the treatment of the pre-wetted substrate in an aqueous system comprising the solid particulate treatment agent in a closed container, the treatment being carried out at a ratio of liquor to substrate which does not exceed 2:1. Typically, the method is applied to the dyeing of textile fibres at liquor ratios of ≤1:1 and is carried out in the absence of additives conventionally included for the sole purpose of promoting dye uptake by controlling electrical interactions or otherwise enhancing interactions between the substrate and the treatment agent. The invention also provides a method for the removal of surplus treatment agents following application of said treatment agents to a substrate, said method comprising not more than three wash-off treatments of said substrate with water following said application. Said wash off process most particularly comprises a two-stage process comprising performing, in order, the steps of: a first wash-off of the treated substrate with water in a closed container at a ratio of water to substrate which does not exceed 5:1; and a second wash-off of the treated substrate with water in a closed container at a ratio of water to substrate which does not exceed 10:1.
