    • The invention concerns oligoesters and/or polyesters with terminal carboxyl groups, characterized in that a) the acid component consists of a1) 10 to 90 % by wt. of dimeric or trimeric fatty acid, a2) 10 to 90 % by wt. of sulphosucinnic acid and a3) 0 to 80 % by wt. of dicarboxylic acids with 2 to 24 C-atoms and containing no sulphonic groups and b) the alcohol component consists of b1) 50 to 100 % by wt. of alkane diols with 2 to 18 C-atoms, b2) 0 to 50 % by wt. of polyalkylene glycols and b3) 0 to 50 % by wt. of dimeric diol and/or trimeric triol, the sulphonic-acid and carboxylic-acid groups being present in the ester as the free acid or as the alkali-metal, alkaline-earth, ammonium, alkylammonium or alkanolammonium salt. Such esters are suitable for the oiling off of leather. Particular properties of leather with such esters are that it is resistant to washing and cleaning, to fogging and to water. In addition, the esters used have "self-fixing" properties, thus making an additional mineral-salt fixing stage unnecessary.
    • 羧基封端的低聚物和/或聚酯,其特征在于:a)酸组分a1)中的存在量为10到二聚体和/或三聚脂肪酸的90%,A2)的存在量为10至90%的磺基琥珀酸和A3的 )存在于的具有碳原子数2〜24磺自由基的二羧酸的0〜80%,和b)醇成分B1)50〜100碳原子数2〜18的链烷二醇的重量%,b2)的0至50 重量的聚亚烷基二醇的%和b3)中0到二聚二醇和/或三聚体的50%(重量),是其中酯存在于以游离形式或它们的碱金属,碱土金属,铵,烷基铵形式的磺酸基和羧基 - 或者可以是链烷醇适用于皮革的注油。 与之皮革处理通过洗涤和清洁牢度,雾化牢度和耐水性良好的特征特别。 另外,这些酯的“自固定”的属性可以是,使得不需要额外的矿物盐的固定。
