Tertiary amine and quaternary ammonium compounds of Formula I and/or Formula II are provided. The present technology also provides compositions that include one or more of the compounds that may be useful for electronics processing (e.g., semiconductor processing composition), cleaning, stripping, degreasing, or a combination of two or more thereof. The compounds of Formula I and/or Formula II may be useful as a low toxicity substitute for tetramethylammonium hydroxide.
An ink-jet recording method is provided. The ink-jet method includes recording an images by ejecting, onto a recording medium by an-inkjet method, a liquid composition containing polymer particles having a glass transition temperature (Tg) higher than the minimum film forming temperature (MFT), a hydrophilic organic solvent, a surfactant, and water under ejection conditions satisfying all of the following (1) to (3):
(1) Tg>the temperature of the liquid composition at the time of ejection>MFT,
(2) MFT>20° C., and
(3) the temperature of the liquid composition at the time of ejection is 30° C. or higher.
The present invention provides an image forming method including ejecting an ink containing a silicic acid compound from an inkjet head, whereby deterioration of the head members is suppressed and a high precision image is formable stably over a long-term, the inkjet head being equipped with plural liquid droplet ejecting elements
80
having nozzles
64
, pressure chamber
58
, supply channel
60
, and piezoelectric element
68
, which transforms vibrating plate
66
that constitutes a wall of pressure chamber
58
, and an ink circulation unit which has common flow channel
52
that is connected with each of plural liquid droplet ejecting elements
80
via supply channels
60
, and common circulation channel
70
that is connected with each of plural liquid droplet ejecting elements
80
via reflux channels
72
, that supplies the ink to plural liquid droplet ejecting elements from common flow channel
52
, and that circulates the ink to common circulation channel.
The present invention provides an image forming method and an ink composition used in the method by which deterioration of a head plate which is formed of silicon is suppressed and more precise images are stably formed, where ink containing an inorganic silicate compound is ejected to form an image from an inkjet head having a nozzle plate where SiO
2
film is provided on a surface thereof at a side toward the ink ejection direction of the nozzle.
The invention provides an inkjet ink composition including a pigment and colloidal silica, the pigment being covered with a water-insoluble resin including a constituent unit having an acidic group, with which rub resistance of images formed and ink discharge reliability are excellent and deterioration of liquid repellency of an inkjet head member is suppressed.
