Abstract: UV-LED ink composition compositions containing a matrix or binder system, one or more colorants, and one or more photo-initiators. In some embodiments, the matrix or binder system is cured using one or more UV-LED sources. In some embodiments, the matrix or binder system contains one or more materials that are polymerized, crosslinked, and/or cured upon exposure to the UV-LED source. This allows the ink composition to be free of any organic solvents. After polymerization and/or crosslinking, the ink is dry. UV-LED ink compositions can be better suited for curing black inks, improve/increase productivity due to its instant on/instant off capability, and produce little or no heat. Such compositions may have environmental benefits as well as the curing process does not produce ozone and requires less exhaust air surrounding the press.

Abstract: Polyvinyl chloride compositions and films formed therefrom are described which exhibit improved printability and resistance to weathering. The compositions generally comprise polyvinyl chloride having a certain molecular weight, at least one bio-based plasticizer, at least one UV absorber, at least one hindered amine light stabilizer, at least one heat stabilizer, and at least one acid scavenger. Also described are various vinyl-based laminates using the films which can be for example adhesive laminates. Also described are methods of producing the noted films and laminates.
