LAYER WITH HOLLOW, SUSCEPTIBLE TO PAINT Russian patent published in 2015 - IPC B42D25/29 D21H19/66 B41M3/14 

FIELD: printing trade.

SUBSTANCE: invention relates to printing and concerns the fraud-proof paper for manufacture of important documents. The paper contains a base with protective element with optically variable properties distinguished when viewing the base from at least its first side and the layer, susceptible to printing paint, which is located on at least first side of the base and which on its first section outside of the section of location of the protective element with optically variable properties, has the first thickness, and on the second section of the base on which the protective element with optically variable properties is located, has the thickness, smaller in comparison with the first thickness. The thickness of the layer, susceptible to paint, within the second section of the base in stepped or stepless manner is decreased starting from the first thickness of the layer, susceptible to paint, which it has on the first section of the base, down to the minimum value.

EFFECT: invention provides creation of the fraud-proof paper on which it is possible to apply the printing image with simultaneous providing the recognisability of optically variable effect created by the protective element located in paper which has optically variable properties.
