Abstract

The present invention discloses an ink-jet recording sheet which, on at least one surface of a support, has a porous ink absorbing layer containing fine particle silica having the average particle size of 0.5 m or smaller produced by wet process, electrolytes such as alkaline metal salts and alkaline earth metal salts, and polyvinyl alcohol; and then has a gloss layer. The ink-jet recording sheet has excellent features, that is, it has gloss like that of photographic printing paper, the excellent ink absorption speed and ink absorption capacity, and does not produce defects of the coating due to the cracks generated during drying in production processes of the ink absorbing layer. Therefore, the ink-jet recording sheet is suitable as a recording sheet for an ink-jet printer.

Description

[0001] technology area

[0002] The present invention relates to an ink-jet recording sheet, and more particularly to an ink-jet recording sheet having photo printing paper-like gloss, high ink absorption speed and ink absorption capacity, and no cracks in the ink receiving layer. Background technique

[0003] The inkjet recording method is a recording method suitable for personal use because inexpensive color printing can be performed with a simple device, and it is rapidly spreading in office and home printing applications. Due to the rapid improvement in image quality due to the realization of full color and high resolution in recent years, it has attracted attention as a simple output format of color images, and it is considered to be one of the most powerful alternatives to silver halide photography. Therefore, there is an increasing demand for inkjet recording sheets having high image quality and high gloss comparable to silver halide photography.
