摘要： PROBLEM TO BE SOLVED: To obtain the subject liquid ink capable of providing a uniform printed image having a text without any crack and a solid region coating at a high optical density and manifesting excellent fastness to water and having superior wet bonding characteristics by including a carrier, a pigment and a curing agent. SOLUTION: This colored liquid ink for ink jet for ink receptor for an acetoacetylated polyvinyl alcohol ink jet is obtained by including (A) a carrier, (B) a pigment and (C) a curing agent. The component C is an aldehyde (e.g. formaldehyde), an active olefin [e.g. bis-(vinylsulfonyl)-methane], a blocked aldehyde (e.g. 2,3-dihydroxy-1,4-dioxane) and an active blocked olefin and is used at a concentration of preferably 0.25-2.0 wt.% of the active components in the colored ink. A biocide in an amount so as to provide 0.005-0.5 wt.% final concentration thereof may be added to the liquid ink.

摘要： PROBLEM TO BE SOLVED: To obtain 100} flat plate-like silver halide particles high in silver concentration in an emulsion at the time of completing a particle growth process and large in average particle diameter and high in average aspect ratio by growing the high chloride 100} flat plate-like particles from a particle nucleus host, and at that time allowing a secondary particle group to act as a silver halide source for growing the flat plate-like particles. SOLUTION: The silver halide emulsion containing a gelatin deflocculant and a specified aqueous dispersion medium and silver halide particle nuclei containing 1-10% of the total silver amount in the photographic emulsion and bromide for promoting growth of 100} flat plate-like particles is prepared in a reaction vessel. The secondary silver halide particle group is formed by adding halide ions containing chloride in an amount of >=50 mol.% of silver the emulsion while limiting the total volume to 0.7-2.0 l/mol of silver and finishing addition of the silver for forming the emulsion layer. The flat plate-like particles having the 100} principal faces are grown by raising the temperature of the dispersion medium and ripening the secondary particle group.
