The present invention refers to an ink-jet recording material comprising a support, and at least one ink receiving porous layer coated on the support, wherein at least one porous layer comprises, dispersed therein, an organic solvent having a logP value higher than 2.00, an antifading compound, a non-ionic surfactant having low EDLB, an anionic surfactant, and a carboxylic derivative.

Ink-jet recording material

The present invention relates to a light-sensitive emulsion, and a light-sensitive photographic material containing the same, comprising silver bromoiodide grains of a core shell structure comprising: a) an inner core consisting essentially of silver bromide or silver bromoiodide and having a silver iodide content within the range of 0 to 10 mole %, and b) a plurality of shells consisting essentially of silver bromide or silver bromoiodide, wherein said silver bromoiodide grains exhibit an average grain size lower than 0.60 micrometer, an average grain thickness lower than 0.15 micrometer, and an average aspect ratio lower than 5:1.

Silver bromoiodide core-shell grain emulsion

One object of the present invention is to provide a mixture composed of 1) a cellulose ether derivative esterified at least with a biprotic acid group derivative expressed by the formula HOOC&mdash;B&mdash;COOH (I), wherein B is a linear aliphatic group represented by (CH,),with x a positive integer from 1 to 5 or is a 5-member or 6-member cycloaliphatic group and 2) a cellulose or cellulose derivative esterified at least with a phthalic acid derivative represented by the following formula (II).
