Abstract
An aqueous ink jet ink composition contains first resin particles formed from a resin other than a polyolefin-based resin and second resin particles formed from a polyolefin-based resin, the ink jet ink composition is used by a recording apparatus which has, at an inside of an ink supply path to supply an ink jet ink composition to an ink jet head, a portion in which members are pushed to each other by an external force, and as the second resin particles, resin particles having a specific surface area of 0.18 m2/g or less obtained from a relaxation time of a pulse NMR are contained.
Claims10
A recording method performed using a recording apparatus which has, at an inside of an ink supply path to supply an ink jet ink composition to an ink jet head, a diaphragm pump or a tube pump having a portion in which members are pushed to each other by an external force, the recording method comprising:
- a supply step of supplying an ink jet ink composition to the ink jet head through the ink supply path;
- and
- an ejection step of ejecting the ink jet ink composition from the ink jet head,
- wherein the ink jet composition contains:
- first resin particles formed from a resin other than a polyolefin-based resin;
- and
- second resin particles formed from a polyolefin-based resin,
- wherein, as the second resin particles, resin particles having a specific surface area of 0.18 m2/g or less obtained from a relaxation time of a pulse NMR are contained.
