| 摘要 |
The present invention relates firstly to a polyester resin bearing at least two functions from among hydroxyl and/or carboxyl functions, based on: A) a polyol component comprising a1) at least one diol bearing at least two lateral C2 to C4 alkyl substituents, a2) at least one diol bearing at least one lateral methyl substituent, a3) at least one C2 to C6 diol bearing no lateral substituent, a4) optionally at least one polyol of functionality >2 and on B) a polyacid component comprising b1) at least one aromatic diacid, b2) at least one C4 to C10 linear aliphatic diacid, b3) optionally, at least one cycloaliphatic diacid, said resin being free of any unsaturated fatty monoalcohol or monoacid. The invention also covers the resin in solution in an organic solvent, crosslinkable compositions comprising said resin, in particular for coatings of metal foils ("coils"), the associated use and the coating as final product resulting from said use. |
