Abstract:
1. A coating composition comprising a compound comprising at least one bicyclo-orthoester group having latent hydroxyl groups and at least one hydroxyl reactive functional group represented by the following formula I wherein x and y are independently selected from 1 to 10; A has the structure according to the following formula II wherein X and Z are independently from each other selected from linear or branched alk(en)ylene groups with 1–4 carbon atoms optionally containing an oxygen or a nitrogen atom; Y is nothing or is selected independently of X and Z from linear or branched alk(en)ylene groups with 1–4 carbon atoms optionally containing an oxygen or a nitrogen atom; one of R B is a divalent radical of aromatic, aliphatic, cycloaliphatic, and araliphatic hydrocarbon groups having 1–40 carbon atoms which groups are linear or branched and optionally contain oxygen atoms, nitrogen atoms, sulphur atoms, phosphorus atoms, sulphone groups, sulphoxy groups, amine groups, amide groups, urea groups, urethane groups, and/or ester groups; ester groups; ether groups; amide groups; thioester groups; thioamide groups; urethane groups; or urea groups; C is a hydroxyl reactive functional group selected from the following formulae: wherein R 3 is selected from the group of alk(en)ylene groups having 1–10 carbon atoms which groups are linear or branched and optionally contain one or more ether, ester, urea, urethane, amide, and/or amine groups, and R 4 , R 5 , R 6 , R 7 and R 8 are independently from each other selected from the group of alk(en)yl groups having 1–10 carbon atoms which groups are linear or branched.
