Aqueous machining fluid compositions, especially aqueous metalworking fluid compositions, are provided that exhibit improved reduction of friction and forces in the mechanical shaping and working of metallic and solid non-metallic workpieces. These compositions comprise a) water, b) a sulfurized organic material selected from the group consisting of sulfurized unsaturated aliphatic carboxylic acids having from 6 to 22 carbon atoms and salts thereof, sulfurized unsaturated esters of aliphatic carboxylic acids having 1 to 22 carbon atoms, sulfurized polymerized unsaturated fatty acids and salts and esters thereof, and mixtures thereof, c) a sulfurized hydrocarbon and d) an aliphatic ester of a dialkyldithiocarbamic acid.

A pigment composition in which an ester compound ordinarily used as a solvent and in other applications, such as butyl acetate or oleyl acetate, is used as a flowability improver for a pigment dispersion and which comprises a pigment and the ester compound as essential ingredients, and a pigment dispersion obtained by dispersing the pigment composition in a solvent, etc. The dispersion is significantly improved in pigment dispersibility and flowability. When the pigment composition or pigment dispersion is used in producing a color filter, a homogeneous film having high contrast can be obtained.
