Abstract
An ink vehicle having a vinyl chloride-vinyl acetate copolymer resin produced by suspension polymerization. In the production of the ink vehicle, the vinyl chloride-vinyl acetate copolymer resin is partially dissolved in a solvent in a state in which an undissolved gel-like component of the vinyl chloride-vinyl acetate copolymer resin is present in the resin. An external force is applied to the solvent containing the gel-like component to dissolve the gel-like component in the solvent.
Claims22
A production method for a vehicle for an ink comprising a vinyl chloride-vinyl acetate copolymer resin dissolved as a binder resin in a solvent, the vinyl chloride-vinyl acetate copolymer resin being produced by suspension polymerization, the method comprising:
- a pre-dissolving step of partially dissolving the vinyl chloride-vinyl acetate copolymer resin produced by the suspension polymerization in the solvent to such a state that an undissolved gel-like component thereof is incorporated;
- and
- a gel-like component-dissolving step of applying an external force to the solvent containing the gel-like component to dissolve the gel-like component in the solvent.
-9. (canceled)
A vehicle for an ink, comprising:
- a vinyl chloride-vinyl acetate copolymer resin that is produced by suspension polymerization and that is dissolved in a solvent in a state in which an undissolved gel-like component present in the solvent is dissolved in the solvent by application of an external force to the solvent.
-14. (canceled)
A production method for an ink cartridge, comprising the steps of:
- storing in a pouch an ink for inkjet recording produced by the production method for an ink for inkjet recording according to claim 8;
- and storing the pouch in a case.
A method of producing an ink vehicle, comprising:
- producing a vinyl chloride-vinyl acetate copolymer resin by suspension polymerization;
- partially dissolving the produced vinyl chloride-vinyl acetate copolymer resin in a solvent in a state in which an undissolved gel-like component of the vinyl chloride-vinyl acetate copolymer resin is present in the resin;
- and
- applying an external force to the solvent containing the gel-like component to dissolve the gel-like component in the solvent.
