Abstract: An object of the present invention is to provide a developer for electrostatic image development, which exhibits stable charge behavior during printing even when using a polyester resin and does not cause contamination of the inside of the apparatus because of less scattering of the toner, and also facilitates easy maintenance.

Abstract: Use of a polyester resin obtained by reacting a divalent or higher epoxy compound, a dibasic or higher polybasic acid compound selected from a polybasic acid and/or acid anhydride and/or lower alkyl ester thereof, and a divalent or higher polyvalent alcohol in a toner for electrostatic charge development containing at least a binder resin, a colorant, and a charge control agent can provide a toner for a non-magnetic single component development having excellent fixing properties, offset resistance and development durability.

Abstract: The present invention relates to pyrrole derivatives, particularly 2-(2-thienyl)-5-(5-tricyanoethenyl-2-thienyl)pyrrole derivatives, which has metallic luster, good stability in air, and a high solubility in an organic solvent, and which is suitable for a film-forming material.

Abstract: On a roadbed layer (4) is formed a cushion layer (5) of 50 mm to 200 mm in thickness which is formed by using elastic chips alone or in mixture with sand, each elastic chip being formed of elastic material and having a size of 7 mm to 0.05 mm, preferably 2 mm to 0.5 mm and a specific gravity of 1.8 to 3.5. The cushion layer (5) contains elastic chips of 3 wt % or more. The elastic chips are formed by mixing a material selected from the group consisting of synthetic rubber, natural rubber and synthetic resin with a specific gravity adjusting material of inorganic powder having a specific gravity of 3 or more.

Abstract: o-Methoxy benzoic acid is produced by reacting chlorobenzoic acids having at least one chlorine atom at least at the ortho position with lower alcohol in the presence of a copper salt and a lower alkyl as a catalyst under moderate reaction conditions. o-Methoxy benzoic acid is useful as an intermediate for pharmaceutical, agricultural chemicals, and the like.

Abstract: An alpha-thio-alpha-aryl-substituted alkanonitrile of the general formula ##STR1## wherein Ar represents an aromatic group, R represents a hydrogen atom or an alkyl group, R.sup.1 represents an alkyl group or an aromatic group, and Y represents an oxygen atom or a carbonyl group. The above compound can be prepared by reacting an alpha-aryl-substituted-alpha-thio-acetonitrile of the general formula ##STR2## wherein Ar, Y and R.sup.1 are as defined above, with an alkylating agent in the presence of a strong base. This compound is useful as an intermediate for producing an alpha-aryl-substituted alkane-carboxylic acid of the general formula ##STR3## wherein Ar, Y and R.sup.1 are as defined above.
