摘要： 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.

摘要： 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 μm, an average width of 2 to 500 μm and an average thickness of at most 1 μm, 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%.
