Abstract
The invention relates to an information record sheet material used for printing. The sheet material is formed by a support and a coating coated at two surfaces of the support, generally, the functional coating is used for coating two surfaces of the support, the coating has aqueous printing ink absorption function, and the coating comprises the chemical composition of aqueous resin, an inorganic pigment and an auxiliary agent. By controlling the components of the chemical auxiliary agent in the coating in a reasonable mode and the components proportion, the good ink absorption effect can be achieved.
Description
Summary: the present invention relates to a kind of information recording sheet printed, this can printing material be to be made up of the coating of support and support two sides, typically at the coated on both sides functional coat of support, this coating has the absorption function of water color ink, and the chemical composition of coating is typically made up of water-base resin, inorganic pigment and auxiliary agent.
Technical field
The present invention is a kind of hard copy sheet material that can be used for image and text output, is particularly suited for inkjet printing and digital printing.
Background technology
Along with the ripe of ink-jet printer was applied in the last few years, the material that can be used for inkjet printing output is also greatly developed, and for the demand of environmental protection, modern ink-jet printer mostly uses water-base ink, a small amount of ink using environmentally-frieweak weak solvent type.And the precision of ink-jet printer also improves constantly, the desktop type ink-jet printer of Seiko Epson Corporation has reached the minimum black of 3 picoliters and measured, so making the fine degree printing image bring up to the level of image output, give birth to therewith application is exactly the invention of the paper consumptive material of output.Hole between the lumber fibre that common paper is formed when relying on papermaking adsorbs ink and carbon dust, but when the precision of output brings up to image level, it is necessary to strengthen the adsorbance of ink, but these common paper cannot be suitable for.Thus have devised the product doing ink-absorbed coated layer on raw base paper or mylar.
The precision of same laser printer is also constantly improving, if it is desired to print out high-quality image with laser printer, common paper just cannot adapt to its requirement, it is necessary to cated material completes this print job.
Digital printing in recent years also presents and the most quickly develops, and it is represented as the Indigo digital printer of U.S. HP, and some short versions or printing in a small amount become its staple market.Some special printing images need also exist for having cated paper and can be only achieved the required precision of its printing.
The present invention is raw with the application of above-mentioned situation, and the present invention mainly applies the coating composition on the thin film of polyester and proportioning thereof, but is not limited to mylar.
United States Patent (USP) 5213873 coating application be hydrophilic silicon dioxide be absorbent body medium, have similar part with point of the present invention, but it mainly apply the coating on paper, and have the features such as dimensional instability.Paper is because of imbibition or shrink the curling or shrinkage produced in coating process, and its finished product also there will be above-mentioned problem during printing, so limiting its application.
United States Patent (USP) 4935307 and 4956230 is all to be coated in above film by ink absorption coating, solve the unstability of paper, but its coating is the resinous coat of a kind of water-swellable type, the blotting speed of this coating itself is slow, and coating is inadequate with the adhesive strength of bottom, also needing to if desired add a bottom increasing bonding force between coating and film, do so adds the cost of product.
Chinese patent CN1213342A is coating to be coated in above film, but it relies primarily on the micropore of mylar own and participates in the absorption of ink, and the problem solving the incomplete absorption of ink not over the formula of coating.
What United States Patent (USP) 6114022 was mainly implemented is coating proportioning composition, and it is using silicon dioxide as main ink-absorbing medium, but when it is not mentioned if be coated in above mylar by the coating of this proportioning, and how the firmness of coating and film improves.
What U.S. Patent Publication No. 2003/0134092A1 was mainly implemented is a kind of inkjet receptive dielectric coated, this coating is made up of silicon dioxide, the size of silicon dioxide particle diameter determines the size of the glossiness after it is implemented, the present invention can reach same glossiness when applying silicon dioxide and hydrated alumina as host inorganic pigment, and when being implemented on mylar, transparency can also reach same level.
Summary of the invention
The present invention relates to a kind of printable recording sheet, this sheet material is made up of mylar support and coating above.Also need to the coating at the backside coating one layer of mylar with antistatic effect if desired.
Above-mentioned coating mainly comprises inorganic pigment, organic resin, auxiliary agent.Wherein inorganic pigment typically by the one in Kaolin, silicon dioxide, hydrated alumina, titanium dioxide, kieselguhr or several in form, it is preferably hydrated alumina, the mixture of silicon dioxide or monomer, its proportion shared in the coating is 10%-90%, preferably 60%-80%.Organic resin is mainly one or several the mixture in the compounds such as polyvinylpyrrolidone, aqueous fiber element, polyvinyl alcohol, starch, aqueous polyurethane, acrylic acid, it is preferably aqueous polyurethane, polyvinylpyrrolidone, the mixture of polyvinyl alcohol or monomer, its proportion shared in the coating is 1%-30%, it is preferably 3%-5%, wherein between polyvinyl alcohol selective polymerization degree 1500-4000, its alcoholysis degree preferred partial alcoholysis degree is 75%-89%, preferably 80%-85%.Polyvinylpyrrolidone selects the product of its homopolymerization series, the preferred 85-105 of its K value.Other auxiliary agent is wetting agent, dispersant etc., and wherein dispersant is generally mineral acid and organic acid, and mineral acid can be chosen for nitric acid, sulphuric acid, boric acid, hydrochloric acid.Organic acid can be chosen for p-methyl benzenesulfonic acid, citric acid, oxalic acid, acetic acid, organic solvent can be selected for DMF, ethanol, isopropanol, n-butyl alcohol, preferably DMF.Preferred compositions of the present invention is acetic acid and N,N-dimethylformamide.Wherein acetic acid proportion in the coating is 0.1%-5%, preferably 0.3%-1%.The shared in the coating proportion of DMF is 1%-20%, preferably 5%-10%.Wetting agent can be selected for nonpolar organosilane-modified product, and its proportion shared in the coating is less than 0.5%.The significantly lifting of its ink absorption performance can be realized by the preferred version of the present invention when this printing material is implemented.Using hydrated alumina and silicon dioxide as coating main pigments, it is big that they have specific surface area, is easily formed the feature of coating high porosity.Hydrated alumina selects to compare surface area more than or equal to 100g/m2, select the aluminium oxide with δ-type crystalline texture the most applicable.Silicon dioxide selects vapor phase method to produce, and the surface area that compares is more than or equal to 150g/m2The most applicable.When both pigment is used in mixed way, the proportion shared by aluminium oxide is that 20%-80% is preferably 20%-25%.When using silicon dioxide and hydrated alumina as main pigments, use acetic acid and N, dinethylformamide is as auxiliary agent, when using polyvinyl alcohol and polyvinylpyrrolidone as main colloid, the hole of the coating that they are formed substantially increases, which adds the absorbability of the ink of coating, reach the effect of the present invention.
The anti-static coating of mylar is coated in the reverse side of support printing surface when necessary.It is typically made up of with colloid the matting agent with hair side function.
With several embodiments, the present invention is described below.But the present invention is not limited to the application of following embodiment.Percentage refers to raw material and accounts for the percentage by weight of whole coating.
