Abstract
The present invention relates to a material intended for forming images by inkjet printing having good stability to ozone and to light as well as a uniform surface, to obtain a high-quality printed image. The material comprises a support and at least one ink-receiving layer, wherein the ink-receiving layer comprises at least one polysaccharide, such as carrageenan, and at least one hydriphillic polymer having hydroxyl groups, such as polyvinyl alcohol and guar gum, and inorganic particles having a neutral or positive surface charge.
Claims15
A material intended for forming images by inkjet printing, comprising a support and at least one ink-receiving layer, wherein said at least one ink-receiving layer comprises carrageenan, a mixture of hydrophilic polymers comprising hydroxyl groups comprising polyvinyl alcohol and guar gum, and inorganic particles having a neutral or positive surface charge, wherein said ink-receiving layer comprises from 80 to 99% by weight of inorganic particles compared with the total weight of the ink-receiving layer.
The material of claim I wherein said inorganic particles having a positive surface charge comprise at least one member selected from the group consisting of zinc oxides, aluminas, zeolites, aluminosilicates, and modified silicas.
