    Abstract: A plating formulation for the electroless deposition of a metal layer on a substrate, wherein a β-amino acid and/or β-amino acid derivative is used as a stabilizer. The β-amino acid is present within a range of 1 mg/L to 2 g/L. Typically, the electrolyte is free of heavy metal stabilizers, cyanides, selenium compounds and sulfur compounds comprising sulfur in an oxidation state between −2 and +5. The inventive plating formulation can comprise 3-aminopropionic acid, 3-aminobutyric acid, 3-amino-4-methylvaleric acid, and 2-aminoethane-sulfonic acid.

    Abstract translation: 用于在基底上无电沉积金属层的电镀配方,其中使用“ - 氨基酸和/或” - 氨基酸衍生物作为稳定剂。 β-氨基酸存在于1mg / L至2g / L的范围内。 通常,电解质不含重金属稳定剂,氰化物,硒化合物和包含-2和+5之间氧化态的硫的硫化合物。 本发明的电镀制剂可以包含3-氨基丙酸,3-氨基丁酸,3-氨基-4-甲基戊酸和2-氨基乙磺酸。
