Photo paper, a composition for forming a dye-receiving layer for producing the same, an ink composition suitable for the same, and an image forming method using the same

摘要

A dye image having a composition comparable to a silver salt-based photographic image can be formed on a photo paper using a water-based ink composition with high saturation and high resolution. In the dye receiving layer 2 of photo paper for forming an image by an ink jet recording method using an aqueous ink composition containing a water-soluble dye, the water-soluble dye can be fixedly retained by an intercalation reaction by ion exchange. Contains intercalating compounds. The intercalating compound is contained in the dye receiving layer 2 in a proportion of 10 to 90% by weight. As such intercalation compounds, montmorillonite group minerals can be preferably used when the water-soluble dye is a cation dye, and hydrotalcite can be preferably used when the water-soluble dye is anionic dye.
