  • Adhesion promoter additive comprising an unsaturated, amorphous polyester
    Patent number: 6794482
    Abstract: An adhesion promoter additive contains at least one unsaturated, amorphous polyester containing 1) an acid component comprising at least one &agr;,&bgr;-unsaturated dicarboxylic acid, and 2) an alcohol component. The alcohol component contains at least 5% of a dicidol mixture of the isomeric compounds a) 3,8-bis(hydroxymethyl)tricyclo[5.2.1.02,6]decane, b) 4,8-bis(hydroxy-methyl)-tricyclo[5.2.1.02,6]decane and c) 5,8-bis-(hydroxymethyl)tricyclo[5.2.1.02,6]decane. Each isomer is present in the dicidol mixture in a proportion of from 20 to 40% by weight. A sum of the isomeric compounds a)-c) is from 90 to 100% by weight.
