摘要： PURPOSE:To obtain sharp printed matter having rapid drying properties by adding porous silica and dye non-adsorbable resin particles t a solvent absorbing layer and reinforcing said layer by a dye non-adsorbable porous resin. CONSTITUTION:A binder is added to a mixture of porous silica and dye non- adsorbable resin particles to prepare a slurry which is, in turn, applied to a base material in a layered form and, next, a dye non-adsorbable porous resin film is laminated to the formed solvent absorbing layer. In order to cleanly peel the solvent absorbing layer, a method wherein a suspension of a mixture consisting of porous silica and the dye non-adsorbable resin particles is applied to a dye support layer and a liquid resin precursor substance becoming the dye non-adsorbable porous resin film is further applied to the coating layer before the suspension is perfectly dried is employed. When printing is carried out, at first, the dye and solvent in ink are absorbed in the solvent absorbing layer and only the dye is supported on the dye support layer. After printing, by peeling off the solvent absorbing layer, sharp printed matter having high color density is obtained.

摘要： PURPOSE:To enable the compatibility of a sufficient ink absorption and transparency(bottom haze) by providing a specific pseudo-boehmite in two layers. CONSTITUTION:A recording medium is provided with a pseudo-boehmite layer with the average pore size of 30-50Angstrom and with the volume of micropores having sizes within the range of + or -10Angstrom of the average micropore size concentrated upon 45% or more of the total micropore volume on a substrate. On the top of that layer, a lower layer provided with a pseudo-boehmite layer with the average micropore volume of 15-30Angstrom and with the volume of pores having a radius within the range of + or -10Angstrom of the average micropores concentrated upon 55% or more of the total pore capacity shows a high ink absorption and an upper layer contributes to the reduction of haze. In the pseudo-boehmite layer, the volume of micropores with the radius of 10-100Angstrom is preferably 0.5-1.0cc/g in the lower layer and 0.3-100cc/g in the upper layer. The thickness of the pseudo-boehmite layer is preferably 2-10mum in the lower layer and 2-15mum in the upper layer.

摘要： PURPOSE:To rapidly fix ink on a printed matter and perform a high-speed printing by providing an alumina hydrate layer on a substrate. CONSTITUTION:As an alumina hydrate provided on a substrate, a pseudo- boehmite, i.e. cohesive material of a colloidal boehmite crystal (AlO(OH)), is preferably used because it improves an ink-adhesive strength. An alumina hydrate layer has a pore structure made of only pores which are substantially 10 - 100Angstrom in radius. When a pore volume is preferably 0.5 - 1.0 cc/g because the alumina hydrate layer has a sufficient absorption and an ink accepting layer has a transparency. As the substrate, a material which has substantially no ink absorption properties is used, such as polyethylene terephthalate or polyester ceramics. The alumina hydrate layer is formed on the substrate by a method wherein a slurry obtained by adding a binder to the alumina hydrate is applied by a roll coater, an air knife coater, blade coater, rod coater, bar coater, or the like and dried.

摘要： PURPOSE:To favorably conduct printing with UV ink by providing an alumina hydrate layer on a substrate. CONSTITUTION:As an alumina hydrate, a pseudo-boehmite is preferably used. The pseudo-boehmite is a cohesive material of a colloidal boehmite crystal (AlO(OH)). An alumina hydrate layer has a pore structure made of pores which are substantially 10 - 100Angstrom in radius. When a pore volume is preferably 0.3 - 1.0 cc/g because the alumina hydrate layer has both a sufficient absorption and a transparency. At this time, if a substrate is transparent, the obtained recording material is also transparent. Even if the substrate is opaque, an ink- adhesive strength can be improved without deteriorating the texture of the substrate. The alumina hydrate layer is formed on the substrate by a method wherein a slurry obtained by adding a binder to the alumina hydrate is applied by a roll coater or the like and dried.

摘要： PURPOSE:To obtain uniform and stable emulsion generating no adverse effect upon porous particles for ink absorption by using a specific quantity of alumina sol as a dispersion medium for ink antioxidant. CONSTITUTION:An antioxidant based on phenol, organic sulphur or phosphite is used for instance, as ink antioxidant. For the dispersion of this antioxidant in alumina sol, for instance, the antioxidant is once dissolved in a low boiling point solvent such as frons or acetone, and the dissolved antioxidant is mixed with alumina sol with a surfactant or the antioxidant is heated at higher than the melting point of the antioxidant with alumina sol and surfactant and then mixed. The dosage of alumina sol is about 5-90pts.wt. in terms of Al2O3 against the total amount of ink antioxidant and alumina sol. The appropriate concentration of alumina sol is about 5-10pts.wt. in terms of Al2O3.
