FIELD: chemical industry; printing industry; other industries; methods of production of the composition of the paint including the optically changeable pigments.

SUBSTANCE: the invention may be used in production of the optically changeable pigments. The optically changeable pigment includes the stratified set composed of the different materials, in which, at least, one of the layers represents the reflecting layer and, at least, one of the other layers represents the dielectric layer. At least, one of the surfaces of the indicated layers is subjected to the chemical action. The indicated materials also include, at least, one of the layers, which represents the semitransparent metallic layer made out of chromium and also one or more metals and-or their inorganic compounds. At that the metal and-or its inorganic compound are subject to corrosion. The subjected to the chemical action surface of the reflecting and dielectric layer along the edge of the layering block of the edge structure of the pigment is coated with the passivating agent, which is selected from the group consisting of the organic esters and the fluorinated organic esters of the phosphoric acid, having the following structural formula: (R_f-CH₂-CH₂-O)_xP(O)(OH)_y, where R_f=F-(CF₂-CF₂)_z, х=1 or 2, у=2 or 1, х+у=3, z=l-7. The composition of the printing paint includes the binding system, water and the optically changeable pigment. The invention allows to diminish oxidation of the metallic layers and dissolution of the dielectric layers of the optically changeable pigment and to use it in the compositions of the printing paint.

EFFECT: the invention allows to diminish oxidation of the metallic layers and dissolution of the dielectric layers of the optically changeable pigment and to use it in the compositions of the printing paint.
