RETROREFLECTIVE SHEET COMPONENT, FILM FOR MAKING SAID COMPONENT, METHOD OF MAKING TRANSPARENT FILM LAYER, STAMPING MATRIX FOR FORMING TRANSPARENT FILM LAYER, METHOD OF MAKING SAID MATRIX, ARTICLE HAVING RETROREFLECTIVE SHEET COMPONENT AND METHOD OF MAKING SAID ARTICLE Russian patent published in 2011 - IPC G02B5/124 

FIELD: physics.

SUBSTANCE: retroreflective sheet component has a transparent layer, having a light-receiving front surface and a retroreflective back surface, arranged such that light can pass from the front surface to the retroreflective back surface, as well as back reflection therefrom. At least part of the elements has at least one face having a non-planar region in which the flat form of the face is violated, wherein face which have non-planar regions lie on the retroreflective surface with formation of an identifier selected for labelling, where a large part of the face having a non-planar region is flat. The identifier is made visible and with possibility of visual recognition when observed at a distance of not more than 20 cm.

EFFECT: possibility of identifying a component when it is not visible from a distance of over 20 cm and absence of negative effect on the retroreflective properties of the component.
