Recorded material

Abstract

Abstract PURPOSE:To improve an image obtained by an ink jet recording system simulta neously in color developing properties, resistance to light and water, by containing a silica which has been surface-treated with a silane coupling agent. CONSTITUTION:A silica which has been surface treated with a silane coupling agent is contained in the recorded face of a recorded material, thus remarkably improving the light resistance of an image made of a water-soluble dye. The silane coupling agent having organic functional groups of epoxy, glycidoxy, amino, mercapto, or methacryl is especially preferred. In an ink jet recording system in which a recording image is formed by using a water-soluble ink, a pigment or filler of high surface hydrophobic properties is not preferable for the content of the recorded material because of the decrease in ink absorp tion and the bleeding of dots. The silane coupling agent having organic func tional groups of not quite high hydrophobic properties is desirably used. The silane coupling agent of a simple or mixed condition is used 0.2-15wt% in relation to 100wt% of the silica. The silica is added to the recorded material approximately 5-30pts.wt. in relation to 100pts.wt. of the recorded material.
