This invention provides a water-reducible oil paint, capable of maintaining a stable suspension of coloring pigment during storage, and having the mechanical, coloring and drying properties of a traditional oil paint. The oil paint comprises a pigment, a base gel composition and an emulsifier- amine soap composition; the base gel composition comprises a traditional drying or semi-drying oil or oil acid, a nonionic or mixed nonionic-anionic emulsifier, having an HLB value in the range of from about 8 to about 18, and a thixotropic gel stabilizer; the emulsifier-amine soap composition comprises at least one amine soap of an acid, selected from mono- and di-unsaturated drying oil acids, and a nonionic or mixed nonionic-anionic emulsifier. The preferred embodiment of this invention is a high-solids artists' oil paint.
A water-reducible artists' oil paint, capable of maintaining a stable suspension of coloring pigment during storage, and having the consistency and the manipulative characteristics of a short, buttery paste, and the working characteristics of a traditional oil paint, as defined in ASTM Method D4302-90, the oil paint comprising a pigment, a base gel composition and an emulsifier-amine soap composition;
A water-reducible, high tinctorial strength oil paint, capable of maintaining a stable suspension of coloring pigment during storage, the oil paint comprising i) from about 0.5 to about 40 parts by weight of a pigment, ii) from about 20 to about 30 parts by wt. of a base gel, iii) from about 2 to about 10 parts of an amine soap, iv) from about 25 to about 50 parts of a drying oil, and v) at least about 8% by wt. of the drying oil of an emulsifier having an HLB value in the range of at least 8 and selected from the group consisting of nonionic and mixed nonionic-anionic emulsifiers.
