Abstract:
1. A coating composition for a thermoplastic substrate, comprising: (A) about 10 to about 60 weight percent of at least one flexible component comprising at least one diacrylate or dimethacrylate ester of a substituted or unsubstituted, linear or branched, diol selected from aliphatic diols containing 3 to about 18 carbon atoms, polyalkylene ether glycols containing 3 to 50 carbon atoms, and cycloaliphatic diols containing about 4 to about 18 carbon atoms; (B) about 10 to about 60 weight percent of at least one aromatic component comprising at least one diacrylate or dimethacrylate ester of a substituted or unsubstituted, linear or branched, diol having a backbone comprising at least one residue of a bisphenol; and (C) about 1 to about 25 weight percent of at least one aliphatic urethane acrylate; wherein said substituted diols contain 1 to 8 substituents independently selected from halo, hydroxy, oxo, C wherein said bisphenol comprises at least one compound selected from the following: bisphenol, bisphenol A, bisphenol F, bisphenol S, bisphenol A epoxy diacrylates and diacrylate esters of ethoxylated bisphenol, propoxylated bisphenol, ethoxylated bisphenol A, propoxylated bisphenol A, ethoxylated bisphenol F, propoxylated bisphenol F, ethoxylated bisphenol S, propoxylated bisphenol S, bisphenol A epoxy diacrylate modified with at least one alkylene glycol or polyalkylene glycol containing 4 to 20 carbon atoms, one or more aliphatic dicarboxylic acids containing 2 to 20 carbon atoms, or a mixture thereof; and wherein said modified bisphenol A epoxy diacrylate comprises residues of at least one aliphatic dicarboxylic acid containing 4 to 8 carbon atoms and propylene glycol.
