Problems solved by technology

[0007] In the past, calcium carbonate was only used as a paper additive and as a coating material for individual light-coated paper (such as cigarette paper). At present, there is no calcium carbonate to replace ultrafine silicon dioxide (SiO 2 ), aluminum oxide, titanium dioxide and other inorganic pigments and resins, which are directly used in color inkjet printing paper and printing photo paper for water-absorbing and ink-absorbing coating layer.

Abstract

The invention provides a plating solution of ink-jet print intermediate which comprises the calcium carbonate as main paint. It is formed by calcium carbonate, adhesive agent, and several additives (agents). Wherein, the calcium carbonate can be one or several ones of heavy calcium carbonate, light calcium carbonate or active calcium carbonate, while the average grain diameter is 0.1mu m-2mu m. The invention uses the calcium carbonate to replace the silicon dioxide, alumina and titanium oxide to be directly plated on the colorful ink-jet print paper and print photograph paper, without changing present paper plating processes, with lower cost and simple device. Therefore, it can make the lower-level paper into high-level paper and save the wood resource.

Description

technical field [0001] The invention relates to a coating material for ink-jet printing media and a preparation method thereof, in particular to a coating material for waterproof printing photo paper. Background technique [0002] Inkjet printing is a non-contact printing method that has many advantages including high-speed printing, low noise, and ease of color printing, so it has been rapidly used in printers and plotters. Inkjet printing enables printing on plain printing paper, coated paper, PPC paper (plain copier paper), medium quality paper, and even plastic films. Inkjet printing technology is gradually popularized and expanded in the field of color image printing due to its characteristics such as easy colorization, low noise, no pollution, and low price. [0003] In recent years, due to the overall development of electronic technology, the storage capacity of digital images has gradually increased, and the color printing images have also increased, and the technol...
