The present invention relates to a method of providing on a surface an active and/or hydrophobic coating which comprises applying to said surface a coating of an organoaluminium compound of the formula
wherein R represents an amido carboxyl moiety selected from the group consisting of:
or
wherein Rl and R2 may be the same or different and are selected from the group consisting of hydrogen, an alkyl radical of rom 1 to about 20 carbon atoms, an aryl or aralkyl radical of from 6 to about 20 carbon atoms, and an alkenyl radical of from 3 to about 20 carbon atoms; R3 is a hydrocarbyl radical of from 1 to about 6 carbon atoms; and the sum of the carbon atoms in R' and R2 is in the range of from 0 to about 40, and the sum of the carbon atoms in R1, R2 and R3 is at least 2; R" is a modifier moiety selected from the group consisting of hydroxyl, an alkoxy radical of from 1 to about 6 carbon atoms, or carboxyl radical of from 1 to about 6 carbon atoms; R' comprises either a group as defined for R, which may be the same or different from R, or an active moiety, said active moiety being bonded to the aluminium by a carboxylate, sulphonate, phosphate, phosphite, oxa or thia linkage.
本发明涉及一种在表面上提供活性和/或疏水涂层的方法,该方法包括在所述表面上涂敷一 层式如下的有机铝化合物涂层
其中 R 代表选自以下组别的氨基羧基
或
其中 Rl 和 R2 可以相同或不同,且选自由氢、1-约 20 个碳原子的烷基、6-约 20 个碳原子的芳基或芳烷基、3-约 20 个碳原子的烯基组成的组;R3 是 1-约 6 个碳原子的烃基;R'和 R2 中的碳原子之和在 0-约 40 的范围内,且 R1、R2 和 R3 中的碳原子之和至少为 2;R "是从羟基、1 至约 6 个碳原子的烷氧基或 1 至约 6 个碳原子的羧基组成的组中选出的改性剂分子;R'包括一个如 R 所定义的基团(可与 R 相同或不同)或一个活性分子,所述活性分子通过羧酸根、磺酸根、磷酸根、亚磷酸根、氧杂环或硫杂环键与铝结合。
