Abstract
A plasma-curable ink composition for offset printing having high reactivity with plasma and capable of being hardened into a sufficiently dried state even in the use of plasma generated by a remote-type plasma generator, and a method for producing printed matter and a method for printing information using the same. The plasma-curable ink composition for offset printing comprises a pigment, a binder resin, and at least one specific ingredient selected from the group consisting of castor oil, polymerized oil, and alkyd resins having an acid value of 10 mg KOH/g or more.
Claims11
An ink composition comprising:
- a pigment;
- a binder resin;
- and
- at least one specific ingredient selected from the group consisting of castor oil, polymerized oil, and alkyd resins having an acid value of 10 mg KOH/g or more, wherein
- a reactivity of the ink composition is configured so that the ink composition is curable by a remote-type plasma which is generated at a site remote from a target substrate and is carried on flowing plasma gas to the target substrate and applied onto the target substrate for offset printing, wherein
- the content of the specific ingredient is 2.5 mass % or more and 14 mass % or less of the entire composition.
A method of producing printed matter, comprising the steps of:
- preparing an ink composition comprising a pigment, a binder resin, and at least one specific ingredient selected from the group consisting of castor oil, polymerized oil, and alkyd resins having an acid value of 10 mg KOH/g or more, a reactivity of the ink composition configured so that the ink composition is curable by a remote-type plasma which is generated at a site remote from a target substrate and is carried on flowing plasma gas to the target substrate and applied onto the target substrate for offset printing,
- printing information on the target substrate with the ink composition, and
- irradiating the printed substrate with the remote-type plasma for curing to fix the ink composition present on a surface of the target substrate, wherein
- the content of the specific ingredient is 2.5 mass % or more and 14 mass % or less of the entire composition.
