Abstract: 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 ?m, 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

Abstract: The present invention relates to a printing ink composition or varnish composition containing a binder component and a solvent component, wherein the solvent component comprises at least one oxymethylene ether and preferably at least one oxymethylene ether according to the general formula (I) CH3[OCH2]nOCH3, wherein n is an integer of 2 to 7.

Abstract: The present invention relates to a polyurethane, which is particularly suitable as binder for a printing ink, which is obtainable by reacting: a) a polyol component including: i) at least one polytetramethylene glycol, ii) at least one diol having a molecular weight of not more than 200 g/mol being different from polytetramethylene glycol, iii) at least one trivalent or higher-valent alcohol having a molecular weight of not more than 6000 g/mol, b) an isocyanate component including at least one organic diisocyanate compound and c) at least one di-functional amine compound and at least one mono-functional amine compound.

Abstract: The present invention relates to a method for determining the composition of a multi-layer system showing a predetermined colour flip-flop effect, wherein the multi-layer system comprises from bottom to top a) a substrate, b) at least one first colour layer containing a colourant, which is arranged on the substrate a), c) on the at least one first colour layer an effect layer containing at least one platelet-shaped effect pigment, and d) on the effect layer c) at least one second colour layer containing a colourant, wherein each of the at least one first colour layer and of the at least one second colour layer contains a colourant being no platelet-shaped effect pigment, wherein the method comprises the following steps: i) specifying a first target value for the colour shade and/or colour brightness of the top side of the multi-layer system seen at a first observation angle, ii) specifying a second target value for the colour shade and/or colour brightness of the top side of the multi-layer system seen at a s

Abstract: 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
