Provided are energy curable inks and coatings that have improved adhesion on flexible substrates, such as non-chemical coated flexible films at fast speed. Also provided are raw material screening methods for quantifying acrylate group concentration, which is used to adjust the ink or coating formula to improve the cure at the surface and bottom and to improve tape adhesion and MEK resistance of energy cured inks and coatings. |
