The blotting covering layer, near support, main effect is that the space between the inorganic pigment that relies in the coating absorbs the solvent among the ink droplet that is injected on the recording materials, makes the ink droplet can be dry immediately, avoids occurring that ink droplet gathers and the even phenomenon of density unevenness that causes in Da Mo amount part.Add the higher particle of hiding rare simultaneously, improve the mist degree of coating, avoid because of seeing that from the lamp box front shape of backlight influences viewing effect.The blotting covering layer contains inorganic pigment, aqueous polymer emulsion, high molecular weight water soluble polymer and cationic fixing agent.
Ink jet recording materials mainly relies on the coating of porous to reach sufficient ink absorption ability, and the adding of inorganic pigment granules in the coating forms the space between inorganic pigment granules, thereby reaches enough ink absorption ability.The kind of inorganic pigment, grain shape and size have direct influence to the ink absorption ability of coating, reach satisfied ink absorption ability, the kind of inorganic pigment, grain shape and size should meet some requirements, in order to guarantee that material has enough ink absorption ability, need to use the bigger inorganic pigment of particle diameter to guarantee the voidage of coating.Among the present invention, infiltration covering layer and the selected pigment of ink solidifying layer can be inorganic pigments such as calcium carbonate, barium sulfate, aluminium oxide, fumed silica, precipitated silica, titanium dioxide, china clay, kaolin.Because satisfy the requirement of the high absorbency of coating, so select the higher precipitated silica of empty capacity rate as main pigment, wherein preferably using particle diameter is 0.5 micron～10 microns precipitated silica.
The ink jet recording materials that is used for full-face spray light box film also should have enough covering powers and light transmittance except having good ink absorption ability.The covering power of coating can use the mist degree of coating or opacity to characterize, and the covering power of coating well then can avoid influencing because of the shape of seeing backlight the viewing effect of lamp box pattern; The light transmittance of coating can use coating density to represent, the light transmittance height of coating then can make lamp box higher in the brightness of the situation hypograph of opening backlight, and image has better expressive force.In order to satisfy the requirement of covering power, also added the inorganic pigment of strong covering power in the blotting covering layer, wherein preferably use the good titanium dioxide granule of covering power.More in order to make coating also have light transmission preferably under the situation that reaches the covering power requirement, more preferably using particle diameter is the superfine titanic oxide of 10 nanometers～500 nanometers.When the particle diameter of titanium dioxide during less than 10 nanometers, titanium dioxide granule shows stronger catalytic oxidation ability when absorbing ultraviolet ray, cause the xanthochromia phenomenon of material under illumination condition easily; When titanium dioxide granule particle diameter during greater than 500 nanometers, the dispersion of the titanium dioxide granule difficulty that becomes is difficult to obtain stable titanium dioxide dispersion system, and titanium oxide dispersion the layering and precipitating phenomenon very easily occurs and influences use.
In order to guarantee that material had both had enough ink absorption ability, have enough covering powers and light transmittance again, inorganic pigment in the blotting covering layer of the present invention adopts being used in combination of above-mentioned two kinds of inorganic pigments, wherein: the weight ratio of precipitated silica and titanium dioxide is 10～1: 1, has solved the xanthochromia problem of product so preferably.
Precipitated silica is a porous type silica, adopts equipment such as high speed shear mulser, ultrasonic disperser, three-roll grinder, sand mill or high-pressure homogenizer that the silica dioxide granule of assembling is dispersed into 0.5～10.0 micron particle.
Contain aqueous polymer emulsion in infiltration covering layer and the ink solidifying layer, its effect is a mechanical performance of improving coating, makes the scratch resistance ability of coating, pliability can both reach level preferably; Can improve simultaneously the waterproof ability of coating.Among the present invention, aqueous polymer emulsion is the water-based bipolymer emulsion that has the ethene section of self-plasticizing action, and its consumption is 5～50 weight % of inorganic pigment.The ethene section can rotate freely in the polymer, it plays the effect of self-plasticization to polymer, such emulsion applications can make coating have good toughness in coating, prevent that effectively material is in the phenomenon that cuts middle appearance " dry linting ", being fit to aqueous polymer emulsion of the present invention can be aqueous polyacrylamide yogurt liquid, the water-based ethylene-vinyl acetate copolymer emulsion, water-based styrene-ethylene copolymers emulsion etc., because also having of ethylene-vinyl acetate copolymer itself is good fast light, weather-proof ability, it can make the fast light of coating, weatherability strengthens greatly, so the present invention preferably makes the use ethylene-vinyl acetate copolymer emulsion.
Among the present invention, have the adding of water-based bipolymer emulsion of the ethene section of self-plasticizing action, make the coating of material have good toughness, effectively prevented the phenomenon of " dry linting " of material in cutting, still, the strength of coating of material is not enough.In order to make coating not only have good toughness but also have enough intensity, the present invention has also added aqueous polyurethane emulsion in infiltration covering layer and ink solidifying layer, especially preferably add cation aqueous polyurethane emulsion, the consumption of aqueous polyurethane emulsion is that inorganic pigment is 2.5～20 weight %.The aqueous polyurethane emulsion addition is very few, and strength of coating increases not obvious, does not reach scratch resistant requirement; The aqueous polyurethane emulsion addition is too much, and then the ink absorption ability of coating can reduce greatly, influences the inkjet printing performance of coating.
Among the present invention, contain the aqueous high molecular resin in blotting covering layer and the ink solidifying layer.The effect of water soluble polymer resin is to form successional coating in the coating dry run, blottings such as inorganic pigment is hidden material be fixed in the coating.The water soluble polymer resin can be one or more in the materials such as gelatin, CMC, carboxymethyl cellulose, starch, polyvinyl alcohol, polyvinylpyrrolidone, polyethylene glycol, wherein preferably use polyvinyl alcohol, particularly the degree of polymerization is the polyvinyl alcohol of 1700～5000 high polymerization degree, the degree of polymerization as pectin/polyvinyl alcohol is too small, and the disadvantage of crackle appears in coating easily; Can make the viscosity of coating fluid big if the degree of polymerization is excessive, thereby make coating process be difficult to control.
Among the present invention, contain color-fixing agent in blotting covering layer and the ink solidifying layer.Color-fixing agent also is modifier, mainly plays fixation and dispersed color.In aqueous dispersion, owing to forming the silanol base, silica particles and water effect have negative electrical charge, agglutination phenomenon takes place in the water soluble polymer resin in silanol base and the coating fluid because of hydrogen bond action, thereby can't obtain the coating of good-looking, so silica dioxide granule needed to use cationic fixing agent that the silanol base of silica dioxide granule silicon face is shielded before forming coating fluid.After silica particles and cationic fixing agent combination, silica particles has positive charge, after the ink droplet that has negative electrical charge is injected into coating surface, the silica dioxide granule combination of positively charged in colour developing group that has negative electrical charge in the ink and the coating, ink is fixed in the coating, thereby prevent ink droplet in coating horizontal proliferation and the image blurring disadvantage that causes makes image have water proofing property simultaneously.The consumption of control cationic fixing agent in ink solidifying layer and blotting covering layer can be fixed on ink in the ink solidifying layer as much as possible, thereby make pattern color saturation degree height, and image is bright-coloured.The condensation body salt that suitable cationic fixing agent of the present invention can be polymine and salt, polyvinylamine and salt thereof, polyallylamine and salt thereof, acrylamide copolymer, dicyandiamide analog copolymer, secondary amine and epihalohydrin etc., the preferred mean molecule quantity that uses is 2000～200000 dimethyl diallyl ammonium chloride copolymer, more preferably 5000～100000.The consumption of cationic fixing agent is 1～20% of an inorganic pigment weight, more preferably 3～10%.
Among the present invention, can also add additives such as crosslinking agent, surfactant, fluorescent whitening agent, ultra-violet absorber, antioxidant, defoamer, anticorrisive agent, pH value conditioning agent in the coating of material, adjust the performance of coating coating fluid,
