A method of manufacturing liposome-containing preparations which contain liposomes exhibiting superior stability in vivo and high enclosure rate of a drug is disclosed, comprising mixing a supercritical or subcritical carbon dioxide, one or more liposome membrane constituents including a phospholipid exhibiting a phase transition temperature and a water-soluble chemical.

Method of manufacturing pharmaceutical preparations containing liposomes

A method of pereparing a rediographic contrast medium containing liposomes is disclosed, comprising (a) dissolving a phospholipid and a sterol in a supercritical or subcritical carbon dioxide in the presence of a compound containing a hydroxyl group or a polyalkyleneoxide group, (b) adding thereto an aqueous solution containing an iodine compound to form micelles and (c) discharging the carbon dioxide to form liposomal vesicles enclosing the iodine compound.

Liposome-containing radiographic contrast medium and preparation method thereof

A silver salt photothermographic dry imaging material comprising a support having thereon a photosensitive layer and a polymer layer, wherein the polymer layer comprises a copolymer of: (i) a fluorine containing acrylate or a fluorine containing methacrylate; and (ii) a monomer having a hydrophobic group in the molecule.

Silver salt photothermographic dry imaging material

A water-based coating composition is disclosed, comprising a latex comprising a polymer impregnated with an infared absorbing compound and a water-soluble polyester or latex comprising polymer containing an active methylene group. An infrared absorbing film and a photothermographic material by use thereof are also disclosed.

Water-based coating composition, infrared absorbing film, and photothermographic material by use thereof

An ink-jet recording medium including a support having thereon an ink receptive layer, wherein the support includes a white-colored substrate and a blue-colored substrate laminated with each other.

Ink jet recording medium

A latex comprising a polymer having an ethylenically unsaturated monomer unit containing an active methylene group and an ethylenically unsaturated monomer unit selected from methacrylic acid ester, acrylic acid ester, maleic acid ester and diene derivative, wherein said polymer is produced in the presence of a water soluble polymer through emulsion polymerization.

Latex and silver halide photographic light-sensitive material containing the same

A latex is prepared by polymerizing a polymerizable monomer having an active methylene group in the presence of a hydrophilic polymer. The hydrophilic polymer comprises an isoprene sulfonic acid or salts thereof as a monomer unit. A sheet material is prepared having a support with a hydrophilic layer containing the latex thereon.

Active-methylene functionalized latex polymer prepared in the presence of a hydrophilic isoprene sulfuric acid polymer, and sheet material comprising same

An adhesive composition is disclosed, comprising an ethylenic copolymer comprising a repeating unit derived from an ethylenically unsaturated monomer containing an active methylene group and at least a repeating unit derived from an ethylenically unsaturated monomer, and a copolyester containing, as a copolymerizing component, a repeating unit derived from a dicarboxylic acid containing a sulfonate group or a repeating unit derived from a diol containing a sulfonate group.
