Abstract

In various types of inkjet printing ink for an industrial usage, since UV ink is able to produce relatively strong film, it has a potential to be used for printing on a plastic substrates.In using UV cure ink with radical photopolymerization method, we found a way to improve poor adhesiveness caused by a curing shrinkage by controlling the molecular structure of monomers.By adjusting the number of molecular weight per methacryloyl group of the monomers, we are able to control the viscoelasticity (tan delta) which represents curing shrinkage and the cured film properties.As a result, we developed an UV cure ink that could control its cured film property depending on the requirement and could be used in a wide range of applications.
