    • The compositions described contain binders, an aluminium pigment and an aqueous thinner. They are characterized in that they contain, as aluminium pigment, a pigment obtained by passivation at a temperature of at least 50 DEG C, preferably between 60 and 90 DEG C and ideally at approximately 80 DEG C of an aluminium pigment, covered with a lubricant, in an aqueous passivation solution containing chromic acid and a water-soluble glycol ether having general formula R (-O-CHR -CH2)nOH (R being a lower alkyl residue, R being either a hydrogen atom or a lower alkyl residue, preferably a -CH3 group, n being a number from 1 to 5) and/or a water-soluble glycol having general formula HO-(CHR -CH2-O-)nH (whereby R is either a hydrogen atom or a lower alkyl residue, preferably a -CH3 group, n being a number from 1 to 5).
    • 所述的组合物包含粘合剂,铝颜料和水性稀释剂。 它们的特征在于它们作为铝颜料含有通过在至少50℃,优选60-90℃的温度下理想地在约80℃下钝化而得到的颜料,该颜料被润滑剂覆盖 在含有铬酸的水性钝化溶液和具有通式R 1(-O-CHR 2 -CH 2)nOH(R ​​1是低级烷基残基R 2)的水溶性二醇醚的水溶液中, 是氢原子或低级烷基残基,优选-CH 3基,n为1至5的数)和/或具有通式HO-(CHR 3 -CH 2 -O-)的水溶性二醇, nH(其中R 3为氢原子或低级烷基残基,优选-CH 3基,n为1至5的数)。
