  • UV-curable compositions comprising cleavage type photoinitiators
    Patent number: 11359102
    Abstract: The present invention is drawn to UV-curable ink and coating compositions comprising cleavage type photoinitiators and acids. The acids may be inorganic or organic acids, or acids generated by a photoacid generator during UV-cure. Incorporation of the acids into the UV-curable ink and coating compositions results in a reduction of migratable photodecomposition products that are produced by cleavage type photoinitiators during UV-cure. The ink and coating compositions are particularly useful for use in applications that require low migration of low molecular weight materials, such as, for example, food packaging.
