    The invention relates to the preparation of plastic films for multi-layered stakes, in particular, to a composition for the preparation of a polyvinyl butyral film,
    The aim of the invention is to increase the resistance of the composition to light aging.
    The stability of the composition to light aging was determined with the aid of the American Standard A 1925, which defines the indicator of regretta, and the German Standard Nr.617A, which determines the total color deviation of 4E. The samples consisting of two glass layers 2.8 mm thick and a 0.8 mm thick polymer film located between them, was first stored at 25 ° C and 55% air humidity for AO hours. Then the image was exposed to two-sided irradiation at varying values within 570-580 nm. The yellowness index was determined by comparison with the results obtained when using between the two glass layers a layer of freshly prepared magnesium oxide, having the same thickness as the polyvinyl butyral film.
    The total color deviation of LUs according to the German Nr standard, 6174, is calculated from the quantitative characteristics of the color of the standard colorimetric CIE system using the equation for determining the color distance 4 Е д, у | д
    In the following examples, the following phenolic stabilizers A-B are used:
    And - bornilkoxy,
    B - dimethyloctylphenyl,

    a - decyldiphenylphosphite;
    b - Tris- (2., 4-di-tert-butylfensh1) - phosphite,
    in - trisnonylphenylphosphite
    d - di-stearyl-pentaerythritol-diphosphite,. .
    d - tetrakis- (2,4-di-tert-butsh1-phenyl) -4,4-bisfenylilene diphosphonitre
    e - trisactylphenylphosphite,
    W - trisnonyl phosphite, 3 - trilaural phosphite,
    and triphenyl phosphite,
    K - tristearylphosphite,
    L - tetrakis- (2,4-dioctylphenyl) -4,4-bisphenylylene diphosphonite and additional stabilizers I-VI;
