Abstract:
A process for the deinking of a coated paper or paperboard is disclosed, the process comprises a step of providing a coating layer comprising a calcium- or magnesium-exchanged clay which is deposited on the paper or paperboard before the ink layer. In a further step said calcium- or magnesium-exchanged clay is activated and the paper is subsequently treated with water.

Claim (Index 1):
A process for the deinking of coated paper or paperboard, comprising the following steps:\n (i) providing a coated paper or paperboard comprising,\n (a) at least one layer consisting of a coating composition comprising,\n (a1) a calcium- or magnesium-exchanged clay, \n (a2) a binder, \n \n (b) at least one layer having a thickness in the range from 0.1 to 10 \u03bcm comprising ink, \n (ii) activating the calcium- or magnesium-exchanged clay before or during step (iii) by,\n (A) carrying out step (iii) with water comprising monovalent ions selected from the group consisting of sodium, lithium, potassium, ammonium and mixtures thereof, and/or \n (B) providing in step (i) a binder (a2) that is soluble in water and comprises monovalent ions selected from the group consisting of sodium, lithium, potassium, ammonium and mixtures thereof, and/or \n (C) adding monovalent ions selected from the group consisting of sodium, lithium, potassium, ammonium and mixtures thereof in form of a salt before or during step (iii), \n (iii) treating the coated paper or paperboard as provided in step (i) with water to obtain an aqueous suspension comprising at least ink, clay particles and a paper pulp or a paper residue, wherein layer (a) is deposited on the paper or paperboard before layer (b).
