Abstract
The invention relates to an ink jet printing medium, especially relating to a waterproof strong-light ink jet printing medium, which includes supporter and ink-absorbing layer, and its characteristic: the ink-absorbing layer contains inorganic pigment and adhesive at particle size 8-15 nanometer and specific surface area 150-200 sq m/g, and it can both absorb dye ink and both pigment ink, and has high glossiness surface, and after printing, it dries rapidly, waterproof, and anti-blotting.
Description
Technical field
The present invention relates to a kind of ink-jet printing media, particularly a kind of waterproof glossy ink-jet printing media.
Technical background
In recent years, because the development in an all-round way of electronic technology, the digitized video storage capacity also progressively increases, and the colour print image also increases thereupon, and the technology of colour print image has also obtained developing rapidly.
Inkjet technology is because characteristics such as its colorize is easy, noise is low, pollution-free, low price, popularizes gradually in the color print image field in recent years and enlarges day by day.Along with the raising of ink-jet technology, the ink droplet of ink-jet printer is more and more littler, and resolution ratio is more and more higher, and the picture quality of printing moves closer to the level of silver salt photo, and for raising the efficiency, print speed is more and more faster.In order to satisfy above-mentioned feature, high-gloss surface is necessary, and print image is water-fast, fast light.For the China ink head that prevents to cause after the ink dried stops up, must use to be difficult for dry ink.In order to obtain the ink of above-mentioned feature, generally in ink, add polyalcohol, adhesive etc., this causes easily prints the dry slow result in back, and because polyalcohol is not volatile, and hygroscopicity is arranged, and causes after the print image drying moisture absorption again, and causing spreads and sinks in oozes.
Disclose a kind of high lustre ink-jetting recording material among the Chinese patent CN1283723, these recording materials are coating ink-receiver layer and cover layers on body paper, and it is 0.01~1.0 micron aluminium oxide and silica that ink-receiver layer contains particle diameter.Because contain hydrophilic gelatin in the cover layer, this recording materials water proofing property is relatively poor.
A kind of like this ink-jet recording sheet is disclosed among the Chinese patent CN1393346, this documentary film is coating ink-receiver layer and a glossiness adjustment layer on base material, ink-receiver layer contains metal salts of organic acids and cationic fixing agent, improve light resistance and ozone resistance, but glossiness and printing back rate of drying are not described.
A kind of ink jet recording materials is disclosed among the Chinese patent CN1388008, this material is the ink-receiver layer of two-layer or multilayer on anti-water carrier and the back coating that mainly contains organic polymer, wherein to contain predecessor be 3~30 nanometers to receiving layer, and to add the average grain greater particle size be that 1~5 micron and mean particle size are that 5~20 microns fine grained improves the transmission property, owing to add oarse-grained fine grained on the top layer, cause surface gloss to reduce easily and be full of cracks.
Chinese patent CN1348868 discloses a kind of recording medium and has used its formation method, this recording medium is coated with two-layer ink absorbing layer on the base material with barium sulfate layer, ink absorbing layer comprises aluminium base pigment, the specific area of the aluminium base pigment in upper strata is greater than lower floor, and this patent is to glossiness and print the not description of back rate of drying.
Summary of the invention
The purpose of this invention is to provide have high-gloss surface, print the back fast drying, have waterproof, the waterproof glossy ink-jet printing media of anti-the oozing property of spreading and sinking in.
Technical scheme of the present invention is: a kind of waterproof glossy ink-jet printing media, comprise support and ink absorbing layer, and it is characterized in that containing particle diameter in the wherein said ink absorbing layer is that 8~15 nanometers, specific area are 150~200m
