Abstract
In order to provide a recorded matter having image fastness to light and gas, disclosed is a recorded matter having an ink-receiving layer of a porous structure, wherein the ink-receiving layer has an image region where an image is formed with a coloring material, wherein the image region has a portion in which all or substantially all of the coloring material distributing in a thickness direction of the ink-receiving layer is embedded in a non-volatile liquid which does not dissolve the coloring material.
Claims19
A method of manufacturing a recorded matter having an ink-receiving layer of a porous structure, the ink-receiving layer having an image region where an image is formed with a coloring material, the method comprising the steps of:
- (i) applying an ink to the ink-receiving layer to obtain an image region where an image is formed with a coloring material contained in the ink;
- (ii) applying a liquid comprising a non-volatile liquid not dissolving the coloring material to the ink-receiving layer;
- and
- (iii) forming a portion in which all or substantially all of the coloring material distributed in a thickness direction of the ink-receiving layer is embedded in the non-volatile liquid by rubbing the non-volatile liquid after it is applied,
- wherein the non-volatile liquid contains an ester of a saturated fatty acid and an alcohol.
A method of improving image fastness of a recorded matter having an ink-receiving layer of a porous structure, the ink-receiving layer having an image region where an image is formed with a coloring material, the method comprising the step of forming in the image region a portion in which all or substantially all of the coloring material distributed in a thickness direction of the ink-receiving layer is embedded in a non-volatile liquid not dissolving the coloring material by rubbing the non-volatile liquid after it is applied, wherein the liquid contains at least one of a silicone oil and a hindered ester.
