About Water-based Paint

A water-based oil paint which comprises a constituent selected from fillers and pigments as well as an aqueous phase comprising one or more water-soluble salts in an amount sufficient to substantially prevent dissolution in the paint of water-soluble organic or inorganic colored substances. The water-soluble salt/salts may be present in a concentration of at or above 10% (weight/volume), in particular at or above 35% such as up to 70% (weight/volume).

A binder, said binder present in said paint composition in an amount of from about 3 to about 20% by weight, based on the weight of said paint composition; Figure oil paintings exhibits the property of substantially preventing dissolution of water-soluble organic or inorganic colored substances present on a surface to which said paint is applied, said paint composition comprising: A hydrophobic agent selected from the group consisting of silicone oil, silicone resin, fluoridated silicone, wax emulsions and polyethylene dispersions, said agent present in said paint composition in an amount of up to about 15% by weight;

Reinforcing fiber, said fiber selected from the group consisting of glass, diastase, polyethylene, polypropylene, polyester, polyacrylonitrile and mixtures thereof, said fibers having a length of from about 2 to 10 mm and present in said paint composition in an amount of up to about 5% by weight; Surface's selected from lecithin, alkyl sulfates, alkyl sulfonates and polytetrafluorethylene derivatives, said surfactant present in said paint composition in an amount of up to about 2% by weight;

A viscosity-reducing agent selected from saccharides, polysaccharides and polyhydric alcohols, said agent present in said paint composition in an amount of from about 1 to about 20% by weight; A crystal formation-retarding agent selected from potassium hydroponically, potassium cyanide  potassium cyanate and potassium thiocyanate, said agent present in said paint composition in an amount of up to about 5% by weight. An anti-foaming agent selected from silicone and fatty alcohols, said agent present in said paint composition in an amount of up to about 0.5% by weight;

The paint is useful for landscape oil paintings of stained interior building surfaces without allowing water-soluble stains to seep through the wet paint. In order to improve the long-term stability of the paint with respect to microbial spoilage, the paint may further contain any of the fungicides and bactericides conventionally used in the hand-painted oil painting for addition to paint. Examples of such preservatives are out-organize derivatives, organometallic derivatives, adamantean derivatives, barium meta-borate, heterocyclic carbamates, etc.

The paint may be prepared by mixing together the constituents. For example, the paint may be prepared by adding the fillers and/or pigments to an aqueous solution of the salt/salts in question in an appropriate concentration, followed by adding the optional binders and/or additives to the obtained mixture.
