Background of invention
In a kind of typical ink mist recording or print system, droplet of ink to spray to recording element or medium at a high speed, produces image from a nozzle on medium.Droplet of ink or recording liquid comprise a kind of record reagent usually, as dyestuff or pigment, and a large amount of solvents.Described solvent or carrier fluid are made of water and a kind of organic matter such as monohydric alcohol, polyalcohol or its mixture usually.
Ink-jet record element typically comprises a kind of carrier, have an ink receiving layer or image formation layer at least one surface of carrier, and comprise that the element that contains opaque carrier that those are used to reflect view and those are used for the element that contains transparent carrier by the transmitted light view.
As everyone knows, in order to obtain and keep the image of photographic quality on image recording element, ink-jet record element is necessary:
Wetting easily, make and do not stir and make muddy, i.e. the combination of adjacent printing ink point, this can cause uneven density.
It is wandering not show image.
Show the ability that absorbs high concentration printing ink and promptly dry, thus avoid when be deposited in later printing product or other surface upward the time element lump together.
Do not show the discontinuous or defective that causes owing to the interaction between carrier and/or each layer, as break, repellency, comb line etc.
Unabsorbed dyestuff is collected on the Free Surface and causes the dyestuff crystallization, thereby cause the frosting or the bronzing effect of image-region.
Have best image fastness, contact to avoid because with water or daylight, tungsten light or fluorescent radiation cause fades.
What wish to obtain is a kind ofly can provide almost the ink setting time of moment and the ink-jet record element of excellent picture quality simultaneously.Yet, consider the required printing ink volume that holds of various ink composites and recording element, these requirements of ink jet recording medium are difficult to realize simultaneously.
