Technical field
[0001]
　The present invention relates to a printing surface mainly vinyl chloride polymers, ethylene - Non-aqueous inkjet ink composition suitable for producing such large size billboards consisting vinyl acetate copolymer, and therewith give on printed material.
Background technique
[0002]
　In a recent billboard advertising, in addition to the vivid and sophisticated design of the logo and patterns, it has been an increase in the one in the photograph tone, such as the face of the goods of appearance and the person. Furthermore, the size of the sign is also, in order to give a strong impact by a person to see, those of large format has come to be very much seen. Conventionally, as a method of fabricating a billboard advertisement, or paste cut the colored sheet in the form of characters in the case of the logo, in the case or to the photographic is possible to use a variety of printing press was common. To that end, it takes a lot of time and effort in the making, also, large-scale equipment of the printing press or the like has a problem that becomes necessary.
　Therefore, in order to produce a clear image signs easier, it attempts to use an inkjet method capable of printing designs created on a personal computer directly to the substrate is performed.
[0003]
　Ink jet system, widely range of material which can be used as a printing substrate, is characterized paper, polymers, metals, that is printable and other hard-soft with ease in a sheet of any material. Especially, in the advertising signs installed outdoors, lightweight and excellent in strength and durability, resistant to rain, because the less expensive such performance is required, it can easily be printed on a polymer sheet having those characteristics, very a great advantage.
　In addition, in recent years, also appeared ink-jet printer of the ultra-wide-format printing width is equal to or greater than 2,000mm, such as large format prints that have been associated with bonding up to now, and can be printed at once, more and more simple It has to be able to manufacture the sign.
　Generally, the polymer sheet used in billboards are used often tarpaulins. Incidentally, tarpaulins as a core material of polyester or polyamide, front and back in polyvinyl chloride and ethylene - a composite sheet obtained by laminating a vinyl polymer such as vinyl acetate copolymer.
[0004]
　These include inkjet ink composition for printing on the composite sheet, an organic solvent (recently-friendly organic solvent environment) non-aqueous inkjet ink compositions based on is used. Non-aqueous inkjet ink compositions, polyvinyl, ethylene chloride is a material of the surface of the composite sheet - with respect to vinyl polymer of a vinyl acetate copolymer, good wettability, drying property, a fixing property, etc. utilizing materials with are required.
　Therefore, utilizing the alkylene glycol monoether monoesters and cyclic esters as an organic solvent (see Patent Document 1), a vinyl polymer as the binder resin, containing a specific amount friendly polyalkylene glycol dialkyl ether to the environment as the organic solvent the use of organic solvent (see Patent Document 2), identifying the amount containing diethylene glycol ethyl methyl ether and propylene carbonate as an organic solvent (see Patent Document 3) are known.
　However, in recent years, has become as higher printing speed is required, when the conventional non-aqueous inkjet ink compositions (especially non-aqueous inkjet ink compositions using friendly organic solvent environment) printed , the solid portion filling (hereinafter referred to as "solid color".) is not sufficient, poor discharge stability, or Motaringu has occurred a problem that occurs.
