Abstract
The invention provides a front spraying light box film with the efficient pigment ink absorbability. The front spraying light box film comprises a PET/PVC (Polyethylene Terephthalate/Polyvinyl Chloride) entire-transparent film, an acrylic resin composite covering bonding coating and a composite polyvinyl alcohol ink absorbing coating which are sequentially arranged; the acrylic resin composite covering bonding coating comprises the following components in percentage by mass: 10%-30% of acrylic resin, 0.1%-0.5% of a coupling agent, 10%-30% of titanium dioxide, 0.5-1% of a binding agent, 0.01%-0.1% of a surface active agent and the balance of water; and the composite polyvinyl alcohol ink absorbing coating comprises the following components in percentage by mass: 5%-20% of polyvinyl alcohol, 0.1%-0.5% of a cross-linking agent, 1%-5% of a dye-fixing agent, 0.05-0.1% of a light stabilizer, 10%-30% of silicon dioxide and the balance of water. The front spraying light box film has the advantages that the absorbability of the coatings on pigment ink is increased, images with a high saturation level can be shown, the special binding agent in the covering layer overcomes the shortcoming that the coatings have poor adhesive force to a supporter, and the physical performance of the finished product is increased.
Description
Technical field
The present invention relates to a kind of full-face spray light box film, be specifically related to a kind of absorbefacient full-face spray light box film of efficient pigment inks that has.
Background technology
Along with developing rapidly of digital technology, the demand of logarithmic code image is more and more higher, and that inkjet technology splices its cost is low, and the print quality advantages of higher has become the main selection of office, family, especially advertisement field.The increase in inkjet printing market is so that various inkjet printing receiver media is increased rapidly.In various inkjet printing receiver medias, the lamp box film is to manufacture the relatively product of difficulty in the ink-jet technology.
Difference according to printing surface, the lamp box film is divided into back of the body blowtorch box film and full-face spray light box film, its structure is all to be coated with at transparent polyester sheet base (PET) sheet base and processes, because production technology and cost are limit, the back of the body take the absorbing dye ink sprays lamp box panel as main in the market, but in use, the lamp box film need be shone by fluorescent tube for a long time, and at this moment the dye ink weatherability is poor, easily the disadvantage such as fade just all manifests one by one.
As a kind of high-end lamp box film, full-face spray light box film is widely used in the fields such as advertising lamp box and digital handicraft with its high resolution, the stronger advantages such as weather-proof row.Yet full-face spray light box film major part is in the market monopolized by international esbablished corporation (Mitsubishi etc.) product, and the price of product is relatively high.Domestic full-face spray light box film is compared with external full-face spray light box film and also had certain gap, is mainly manifested in: the ink absorption ability to paint ink is not enough, can not satisfy 400% stamping ink amount demand; Physical property is poor, and the attachment fastness of coating and support is inadequate, and coating is more easily scratched and destroys.
Summary of the invention
Deficiency for back of the body blowtorch box film and domestic existing full-face spray light box chip technology the invention provides a kind of absorbefacient full-face spray light box film of efficient pigment inks that has.
The present invention is comprised of the compound covering adhesive coatings of PET/PVC all-transparent film, acrylic resin and the composite polyvinyl alcohol ink-absorbed coated layer that set gradually; The compound cover coating of acrylic resin contains following component by described mass percent: acrylic resin 10% ~ 30%, and coupling agent 0.1% ~ 0.5%, titanium dioxide 10% ~ 30%, adhesive 0.5% ~ 1%, surfactant 0. 01% ~ 0.1%, surplus is water; Described composite polyvinyl alcohol ink-absorbed coated layer contains following component by described mass percent: polyvinyl alcohol 5% ~ 20%, and crosslinking agent 0.1% ~ 0.5%, color-fixing agent 1% ~ 5%, light stabilizer 0.05% ~ 0.1%, silica 1 0% ~ 30%, surplus is water.
The present invention has not only improved the absorbability of coating for pigment inks, can show the image of high saturation, and in addition, distinctive adhesive has overcome the shortcoming of coating and support poor adhesive force in the covering layer, has improved the physical property of finished product.
