  • UV-CURABLE COMPOSITIONS COMPRISING ACYLPHOSPHINE OXIDE PHOTOINITIATORS
    Publication number: 20210115273
    Abstract: The present invention is drawn to UV-curable ink and coating compositions comprising acylphosphine oxide 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 aldehydes that are produced by acylphosphine oxide photoinitiators during UV-cure. The ink and coating compositions are particularly useful for use in applications N that require low migration of low molecular weight materials, such as, for example, food packaging.

  • ACTINIC RADIATION CURABLE COMPOSITIONS INCLUDING SEMICONDUCTOR METAL OXIDE MATERIALS
    Publication number: 20210087421
    Abstract: Described herein are inks and coating compositions comprising semiconductor metal oxides and composites thereof, which are natural environmentally sustainable materials that may be recycled and/or reused indefinitely. Semiconductor metal oxides offer an alternative to relatively more toxic, non-sustainable, photo and heat-degrading, migrating traditional photoinitiator agents used in actinic radiation curable compositions. The semiconductor metal oxides and composites thereof absorb visible or UV-light as photocatalysts and/or semiconductors, or absorb electron beam radiation, forming radicals for radical events as polymerization reactions and color enhancement events.
