FIELD: polymer items possessing fluorescent properties and property of reflection in opposite direction; information and signaling appliances.
SUBSTANCE: proposed sheet item has sublayer of film coated with fluorescent paint at concentration of from 0.001 to 1.5 wt-% relative to polymer matrix of sublayer, film of overlayer coated with fluorescent paint at concentration of from 0.001 to 1.5 wt-% relative to polymer matrix of overlayer. Fluorescent film of overlayer coated with paint possesses higher resistance to light as compared with sublayer film. Sheet of painted fluorescent film of overlayer lies over sheet of sublayer fluorescent film. Sheet item has selected fluorescent color different from color of overlayer fluorescent film and from color of sublayer fluorescent film. Specification gives description of production of such items.
EFFECT: enhanced resistance to action of atmospheric conditions; enhanced durability of color; wide range of color.
