The paint has superior physical and chemical properties, in particular light fastness and water resistance, however, in the proposed compositions were not taken into account the time and energy specifics of photophysical processes.

It is known that for complex composite materials shortwave UV radiation has a greater negative impact than long-wave radiation. P the listed disadvantages of the proposed compositions can be eliminated, if you make a cascade mechanism of energy transfer in the composition. The migration energy in such compositions can be carried out inductively resonance and exchange resonance mechanisms (Krasovitsky BM, Bolotin A.B. "Organic phosphors", M.: Khimiya, 1984).

To implement these mechanisms of energy transfer are suitable so-called photosensitizers that absorb short-wave UV radiation and transfer it to the phosphor. Joint use of photosensitizers and phosphors (optical brighteners) allows you to extend the range of the absorbed energy and convert short-wave UV radiation in the wavelength that increases the light resistance of the compositions.

Object of the present invention is to provide a colored water-dispersion paints with high performance, in particular high weather resistance, light resistance, color stability characteristics.

The problem is solved due to the fact that the water-dispersion paint containing acrylic film-forming, dioxide Titta and colored pigments, chalk and/or talc, polyoxyethylene ether of alkylphenol, the dispersant is a sodium polyphosphate, antifoam, preservative, ammonia (25%aqueous solution), antifreeze - ethylene glycol, a thickening agent and water, contains the as film-forming copolymer of styrene and esters of acrylic acid or a copolymer of styrene and acrylic acid, as a thickener - redkosty copolymer of butyl acrylate, methacrylic acid and styrene or methylolacrylamide, and additionally contains coalescent - butyldiglycol, optical Brightener, light and photosensitizer in the following ratio, wt.%:
