ENERGY CURABLE INKS WITH IMPROVED ADHESION

摘要

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.

主权项

1. An energy curable printing ink or coating composition, comprising a monomer containing an acrylate group or oligomer containing an acrylate group or a combination thereof, wherein the composition has a relative acrylate group concentration >4.0.
