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...
