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.

摘要:
The present invention relates to a process for easily and efficiently producing silica particles having a narrow particle size distribution and a high porosity from inexpensive starting materials such as sodium silicate. The silica particles of the present invention can be obtained in the form of a slurry containing them by (1) forming a slurry by mixing first particles difficultly soluble in an alkali and soluble in an acid, with an aqueous alkali silicate solution to form a first slurry containing the first particles, (2) neutralizing the first slurry with a mineral acid to prepare a second slurry containing second particles wherein silica is deposited on the first particles, and (3) adding a mineral acid to the second slurry to dissolve the first particles from the second particles, to prepare a third slurry containing silica particles. When the silica particles of the present invention are used as a filler even in a small amount for paper making, the resultant papers have excellent brightness, opacity, opacity-after-printing, etc.
