The present invention relates to a system, which comprises: b) at least one first colour layer containing a dye and/or pigment, c) on the at least one first colour layer an effect layer containing at least one platelet-shaped effect pigment, wherein the at least one platelet- shaped effect pigment is composed of particles having an average length of 2 to 500 m, an average width of 2 to 500 m and an average thickness of at most 1 gm, and d) on the effect layer at least one second colour layer containing a dye and/or pigment, wherein each of the at least one first colour layer and of the at least one second colour layer contains a dye and/or pigment being no platelet-shaped effect pigment, wherein the at least one dye and/or at least one pigment included in the at least one first colour layer is different from the at least one dye and/or at least one pigment included in the at least one second colour layer, and wherein, at least if the at least one first colour layer has a sum of reflectance and scattering of less than 40%, the system further comprises: a) below the at least one first colour layer a lower layer containing a pigment and having a sum of reflectance and scattering of at least 40%.

The present application relates to the field of black coloring of materials made from wood, such as reconstituted wood panels or paper/cardboard. The black coloring composition for wood-based materials includes a black pigment, a reactive type black dye and water. It is also possible to prepare a dry extract for some special applications.

The present invention includes a label, a label sheet and a method for manufacturing the label. The label includes a paper facestock having first and second surfaces and a layer of pressure sensitive adhesive proximal to the second surface. The label can be adhered to a substrate having pre-applied indicia to cover the indicia and the label is opaque enough to prevent the viewing of the covered indicia while matching the color of the substrate.

Process for the surface treatment of a titanium dioxide pigment, characterized in that it comprises the following steps: an aqueous suspension of titanium dioxide pigments is formed, in a first step, a layer of alumina phosphate is precipitated on the surface of the pigment, in a second step, a layer of alumina is precipitated over the first layer of alumina phosphate, and in an optional third step, a layer of magnesium oxide is precipitated on the layer of alumina. Titanium dioxide pigments made by the disclosed process and method using said pigments in paper manufacturing are also disclosed.

The present invention relates to the technical domain of additives for aqueous high solids suspensions of mineral materials. The inventive additive comprises specific primary amines and is used for increasing the pH-value of the suspension and/or for increasing the wettability of the mineral materials.

The present invention resides in a lamination or specialty paper, such as dcor paper, suitable for lamination, wherein the paper has a furnish in which the fibre portion comprises between 1% and 100% non-wood pulp. Also disclosed is a method for making a non-wood based paper comprising forming an unrefined slurry of bleached or unbleached non-wood pulp, blending the slurry with chemical or mineral additives, and passing the slurry into a paper-making machine.
