ARTICLE WITH CURVED PATTERNS FORMED FROM ALIGNED PIGMENT FLAKES Russian patent published in 2020 - IPC B41M1/00 

FIELD: printing industry.

SUBSTANCE: in the printed product, the pigment flakes are leveled by the magnetic field such that curved patterns are formed in a plurality of cross-sections, normal continuous imaginary lines, in which radii of bent patterns increase along imaginary line from first point to second point. When light falls on the aligned pigment flakes from the light source, light reflected from the aligned pattern forms a bright image, which looks as gradually changing its shape and moving from one side of continuous imaginary line to other side of continuous imaginary line when substrate is inclined relative to light source.

EFFECT: disclosed is an article with curved patterns formed from aligned pigment flakes.
