ABSTRACT:
An ink jet-recording sheet for forming recorded images using liquid ink comprises a combination of specific compounds, for instance, 1,2-bis(2-hydroxyethylthio)ethane and a homopolymers or copolymer of diallylamine type compounds such as poly(diallylamine)hydrochloride, poly(diallylamine)sulfate, poly(diallylamine) phosphate or poly(diallylamine)acetate. The ink jet-recording sheet can ensure a high density of printed images, can provide images having high quality, shows only a slight color change and discoloration of printed images even when exposed to ozone gas and is excellent in the long-term shelf life.
