Ink-jet recording material used for full-face spray light box film

Abstract

The invention discloses an ink-jet recording material used for a full-face spray light box film, which comprises a support body, an ink fixing layer and an ink-absorbing covering layer. The ink fixing layer and the ink-absorbing covering layer respectively contain inorganic dyes, aqueous polymer emulsions, water-soluble high polymer resin and cationic fixing agents; the inorganic dyes in the ink-absorbing covering layer are silica with 0.5 to 10 micrometers by a precipitation method and titanium dioxide with 10 to 500 nanometers; the inorganic dye in the ink fixing layer is silica with 0.5 to 10 micrometers by a precipitation method; and the aqueous polymer emulsions in the ink fixing layer and the ink-absorbing covering layer are an aqueous biopolymer emulsion with an ethylene segment with self-plasticizing action and an aqueous polyurethane emulsion. The recording material has the advantages of good light fastness, weather resistance and scratch resistance, high image color saturation, good covering power and high light transmission.

Description

technical field [0001] The present invention relates to an ink-jet recording material, and more particularly to an ink-jet recording material for positive-blowing torch film. Background technique [0002] In recent years, the advertising industry has developed rapidly, and almost all enterprises and merchants have spared no effort to promote themselves and their products. The forms of advertising carriers are becoming more and more diverse, and the quality requirements for advertising carriers are also getting higher and higher. Among many advertising carriers, inkjet printing is widely used due to its cheap hardware, fast and convenient output, and noiseless work. Especially with the continuous improvement of printer performance, the factors that restricted the application range of inkjet printing in the past, such as slow output speed and lack of image quality, have been well resolved. Now the output speed of inkjet printing is almost the same as that of silver salt color...

Problems solved by technology

[0004] Publication number is that the Chinese patent of CN 1970308A discloses a kind of waterproof inkjet positive spray film, and it comprises support body, bottom layer, solid ink layer and ink penetration layer, and its improvement is that solid ink layer contains chain type unsaturated bond structure High polymers and inorganic pigments, wherein the particle size of the inorganic pigments is 0.5 to 10 μm, and the amount of high polymers with a chain unsaturated bond structure is 5 to 30 parts relative to 100 parts of the inorganic pigments; the ink penetration layer contains benzene- Olefin-based binary copolymer inorganic pigments, wherein the particle size of the inorganic pigment is 0.5-10 μm, and the amount of the binary copolymer is 5-40 parts relative to 100 parts of inorganic pigments, which solves the problem of poor waterproof performance and absorption of inkjet film The problem of poor ink performance

But this product has the following defects: 1. The light box film is due to the use of a benzene-olefin binary copolymer as an auxiliary film-forming material. Under the conditions of light and high temperature and high humidity, the benzene-olefin binary copolymer Oxygenation and yellowing will quickly occur, which will affect the service life of the light box film, and will cause the film to be more brittle, and the mechanical properties of the coating surface will be poor, and there will be "powder falling" when scratching or cutting; 2 .Because the solid ink layer of the light box film is close to the support side, when printing with pigment ink, the ink cannot be effectively fixed, resulting in poor water resistance of the image and low pattern density; 3. Since only silicon dioxide is used as the Inorganic pigments, the covering power of the coating is insufficient, and it is easy to cause the problem that the backlight affects the viewing effect of the image
