摘要

2047669 9010660 PCTABS00002 Free-radical curable compositions contain (1) at least one of an oligomer having an average of at least one electron-rich ethylenically unsaturated group per molecule of oligomer and a polyester having a saturated polyester backbone and an average of at least one electron deficient ethylenically unsaturated end group per molecule and (2) at least one of a single functional diluent, a mixture of single functionality diluents and a dual functional monomer wherein the ratio of electron-rich double bonds to electron deficient double bonds in the composition is in the range of about 5:1 to about 1:5 and a desired viscosity. These compositions are useful as coatings for various substrates.
