FIELD: printing equipment.
SUBSTANCE: invention relates to ink for digital piezojet printing and can be used in making outdoor advertising structures. Light-fast UV-curable ink for piezojet printing includes monofunctional acrylates, trimethylolpropane triacrylate, lactams, dispersants, rheology control components, inorganic pigments, components for photochemical initiation of radical polymerisation, Photomer 5006 polymerisation co-initiator and self-polymerisation inhibitors. Monofunctional acrylates are selected from phenoxypolyethylene glycol acrylate, Genomer 1122 and Miramer M140, lactams—from N-vinylcaprolactam and N-vinylpyrrolidone. Dispersants are salts of polyester of phosphoric acid, components regulating rheological properties—BYK UV-3500 or Disperbyk-111, components for photochemical initiation of radical polymerisation—ethyl (2,4,6-trimethylbenzoyl) phenylphosphinate, self-polymerisation inhibitors—2,6-ditrebutyl-4-methylphenol or GENORAD 22.
EFFECT: invention provides increased light fastness and flexibility of the printed layer of UV-curable ink, as well as absence of smell during printing.
