Patent No. U.S. 7,071,286 B2

E. I. duPont de Nemours and Co. has obtained a patent for a coating composition comprised of 20-80% weight of at least one orthoester compound having at least one non-cyclic orthoester group and at least one free hydroxyl group per molecule, which compound is obtained by reacting at least one orthoester compound with at least one diol with a number average molecular weight (Mn) of 200-1000 g/mol, wherein solely diols are used having hydroxyl groups with different reactivity and having more than three carbon atoms between the hydroxyl groups and ...
