VEHICLE INTERNAL PLATE PART COATING Russian patent published in 2018 - IPC C09D201/00 C09D7/12 B05D7/14 

FIELD: transportation; manufacturing technology.

SUBSTANCE: invention relates to the vehicle inner plate part coating comprising a perylene-based pigment and an iron oxide-based pigment, which are contained as pigments to produce a specific color, similar to the outer plate coating color, wherein the iron oxide-based pigment average particle size is equal to or greater than 10 nm and is equal to or less than 60 nm. At that, the perylene-based pigment content in the inner plate part coating is equal to or greater than 10 % and equal to or less than 14 % by weight, and the weight ratio of iron oxide-based and perylene-based pigment content in the coating of the inner plate part is equal to or greater than 0.4:12.3 and equal to or less than 2.0:10.7. Vehicle inner plate part coating is used in combination with the vehicle outer plate part coating, containing the perylene-based pigment and satisfying the 278.8≥(R^OH(P)/R^OH(OA))≥74 condition, and where R^OH(P) is the reflection coefficient in high lights at the peak wavelength, where the reflection coefficient has a maximum on the reflection coefficient spectral curve and where R^OH(OA) is the average reflection coefficient in high lights for the wavelength range of additional colors, which combines the color tone of the additional color for the color tone to which the specific color belongs on the Munsell color tints circular diagram with ten divisions.

EFFECT: achievement of high color saturation in high lights both in the inner plate part coating and in the outer plate coating, and also a high durability of a vehicle internal plate part coating is achieved.
