FIELD: chemistry.
SUBSTANCE: invention relates to anti-fingerprint protective covering composition, with said covering composition containing silane oligomer, in which present are: group R1, represented by formula 1 [RaO-(CH2CH2O)p-Rb-], in which Ra is selected from the group, consisting of hydrogen atom and alkyl group, which contains from 1 to 3 carbon atoms; Rb is selected from the group, consisting of alkyl group, which contains from 5 to 20 carbon atoms, alkenyl group, which contains from 5 to 20 carbon atoms, alkynyl group, which contains from 5 to 20 carbon atoms, aryl group, which contains from 5 to 20 carbon atoms, arylalkyl group, which contains from 6 to 20 carbon atoms, cycloalkyl group, which contains from 5 to 20 carbon atoms, and heteroalkyl group, which contains from 5 to 20 carbon atoms; and p represents integer number from 1 to 12; and group R2, represented by formula 2 (Rc)q, in which Rc represents cycloalkyl group, which contains from 3 to 20 carbon atoms; and q represents integer number from 1 to 3, where silane oligomer has structure, represented below by formula 3: 
in which m and n independently on each other represent integer numbers from 1 to 10. Anti-fingerprint protective covering composition is produced by mixing silane compound, which contains alkyl group, with distilled water or acid.
EFFECT: according to invention obtained is thin film, which prevents appearance of well-seen fingerprints on displays or sensor panels and demonstrates perfect properties of longevity and sliding.
