MULTILAYER COATING FILM AND COATED OBJECT Russian patent published in 2019 - IPC B05D7/24 B05D5/06 B05D1/36 

FIELD: technological processes.

SUBSTANCE: invention relates to multilayer film coatings with metal effect for body or other component of vehicle and relates to multilayer coating film and coated object. Film (12) comprises lower coating film (14) and upper coating film (15). Lightness index L* of coating film (14) is 30 or less. Coating film (15) contains flakes (22) of aluminum. Each of aluminum flakes (22) has surface roughness Ra of 30 nm or less and thickness of 70 to 150 nm. 70 % by weight or more of aluminum flakes contained in coating film (14) have length of major axis from 7 to 15 mcm and ratio of geometric dimensions 3 or less. When all flakes (22) of aluminum contained in upper cover film (15) project on surface of upper coating film (15), occupied part of protruding surface area, which is part of area occupied by projecting on surface of aluminum flakes (22) of upper coating film, is from 40 to 90 %.

EFFECT: invention provides a coating with a texture of a well-polished metal, diffusion reflection in which is not mirror-like geometric optical reflection.
