    • An aqueous dispersion, contains: a) an amorphous urethanized, unsaturated polyester resin, b) a nonvolatile content of from 20% to 60% by weight, c) from 0 to 60% by weight of a solvent, d) a pH of between 5.0 and 9.5, and e) a viscosity at 20° C. of from 20 to 500 mPas. The polyester resin is obtained from I. an alcohol component, II. i) from 20 to 100 mol % of an α,β-unsaturated carboxylic acid component, and ii) from 0 to 80 mol % of a further carboxylic acid component, and III. at least one isocyanate component. The alcohol component contains a dicidol mixture of the isomeric compounds 3,8-bis(hydroxymethyl)tricyclo[5.2.1.02,6]decane, 4,8-bis(hydroxymethyl)tricyclo[5.2.1.02,6]decane and 5,8-bis(hydroxymethyl)tricyclo[5.2.1.02,6]decane. Each isomer is present in a fraction of from 20 to 40% in the dicidol mixture. The sum of the three isomers in the dicidol mixture is from 90 to 100%. The dicidol mixture is present from 10 to 100 mol % in the alcohol component of the polyester.
    • 水分散体包含:a)无定形氨基甲酸酯化不饱和聚酯树脂,b)20%至60%重量的不挥发物含量,c)0至60%重量的溶剂,d) 5.0和9.5,e)20℃下的粘度为20-500mPas。 聚酯树脂是由I.一种醇组分II获得的。 i)20至100摩尔%的α,β-不饱和羧酸组分,和ii)0至80摩尔%的另外的羧酸组分,III。 至少一种异氰酸酯组分。 醇组分含有异构化合物3,8-双(羟甲基)三环[5.2.1.0 2,6]癸烷,4,8-双(羟甲基)三环[5.2.1.0 2,6-二甲基癸烷和5,8-双(羟甲基)三环[5.2.1.0 2,6]癸烷。 每种异构体在二糖混合物中的分数为20至40%。 二酯混合物中三种异构体的总和为90〜100%。 二聚体混合物在聚酯的醇组分中以10至100mol%存在。
