A surface treatment composition containing a complexing agent as a metal deposition preventive in a liquid medium, in which the complexing agent is an ethylenediaminephenol derivative of the following general formula (1) or its salt:
wherein X1 and X2 are hydroxyl groups; Y1 to Y8 are respectively independently a hydrogen atom, a hydroxyl group, a halogen atom, a carboxyl group, a phosphonic acid group, a sulfonic acid group, a carbonyl group, a nitro group, a nitroso group, an amino group, an imino group, a nitrilo group, a nitrile group, a thiocyanate group, a hydroxyamino group, a hydroxyimino group, or an alkyl or alkoxy group which may have a substituent, provided that at least one of Y1 to Y8 is not a hydrogen atom; Z1 to Z4 are respectively independently a hydrogen atom, a carboxyl group or a sulfonic acid group; and R1 to R4 are respectively independently a hydrogen atom or an alkyl group which may have a substituent.
一种含有络合剂的表面处理组合物,作为液体介质中的金属沉积防止剂,其中的络合剂是下式通式(1)的乙二胺苯酚衍生物或其盐:
其中 X1 和 X2 为羟基;Y1至Y8分别独立地为氢原子、羟基、卤素原子、羧基、膦酸基、磺酸基、羰基、硝基、亚硝基、氨基亚氨基、硝基、腈基、硫氰酸基、羟基氨基、羟基亚氨基、或可具有取代基的烷基或 烷氧基,条件是 Y1 至 Y8 中至少有一个不是氢原子;Z1 至 Z4 分别独立地为氢原子、羧基或磺酸基;以及 R1 至 R4 分别独立地为氢原子或可带有取代基的烷基。
