Abstract
Electron beam curable compositions comprising polyols, and any blend of ethylenically unsaturated monomers and oligomers. The polyols of the invention are preferably essentially free of any ethylenically unsaturated groups, have greater than one hydroxy group and preferably have boiling points in excess of 170° C.
Claims27
Electron Beam (EB) curable compositions comprising alcohol containing substances, which are essentially free of ethylenically unsaturated groups, wherein the alcohol is selected from the group consisting of propylene glycol, trimethylolpropane, glycerol, diethylene glycol, triethylene glycol, tetraethylene glycol, dipropylene glycol, tripropylene glycol, poly(ethylene glycol), poly(propylene glycol), ethoxylated trimethylolpropane, propoxylated trimethylolpropane, ethoxylated pentaerythritol, propoxylated pentaerythritol, ethoxylated ditrimethylolpropane, propoxylated ditrimethylolpropane, ethoxylated dipentaerythritol, propoxylated dipentaerythritol, and combinations thereof, wherein the compositions further comprise one or more ethylenically unsaturated monomers, and wherein the concentration of monofunctional monomer is less than 20% by weight of the total composition.
