The present invention relates to a coating composition for coating of paper or paperboard, said composition comprising: a pigment, a binder, an optical brightening agent (OBA), a colorant, and a sugar alcohol, and to paper or paperboard coated with at least one layer of the coating composition. The present invention further relates to a method for preparing said coating composition and to an OBA premix useful in the method of preparing the coating composition, said premix comprising an OBA, a sugar alcohol, and optionally a colorant, wherein the OBA and sugar alcohol together make up at least 10% by weight, preferably at least 20% by weight, based on the total weight of solids in the premix.

The ink composition comprises pigment particles and a stimulus responsive dispersing agent for dispersing said pigment particles in a protic polar solvent, for instance for inkjet printing, which stimulus responsive dispersing agent comprises an anchoring part for anchoring to said pigment particles, a stimulus responsive part as shown in formula (XXa) or (XXb) and a hydrophilic part for solvent stabilization of the pigment, wherein the stimulus responsive part upon exposure to a stimulus initiates decomposition of the stimulus responsive dispersing agent. The paper with the printed ink can be deinked in an industrial deinking process.
