Description

technical field

[0001] The present invention relates to aqueous ink compositions. Background technique

[0002] The printing method using the inkjet recording method is performed by scattering and adhering ink droplets to a recording medium such as paper. Due to the innovative progress of inkjet recording technology in recent years, the printing method using inkjet recording method has begun to be used in the field of high-definition image recording (image printing) that has been using photography and offset printing until now. Therefore, not only the commonly used plain paper and special paper for inkjet recording (matt type, glossy type), but also printing paper, synthetic paper, film and other ink non-absorbing or low-absorbing recording media have begun to demand high Quality print.

[0003] In recent years, there has been research on ink combinations that can record not only on the above-mentioned plain paper and special paper for inkjet recording, but also on film-ba...
