ABSTRACT:
Disclosed are radiation-curable compositions comprising at least one ortho-phthalate (meth)acrylate, and optionally a (meth)acrylate monomer, a stabilizing package, an adhesion promoter, and/or a photoinitiator. The compositions maintain physical integrity when cured and then aged for seven days under the conditions of 70% relative humidity, 77° C. black panel temperature, 55° C. chamber air temperature and a light intensity of 0.51 W/m2
m at 340 nanometer wavelength passed through a daylight filter. The preparation and use of these compositions are also disclosed.
