Embodiment Construction
[0035] Hereinafter, the present invention will be described in detail with reference to the drawings.
[0036] figure 1 Is a cross-sectional view of the retroreflective plate according to the present invention, figure 2 Is to figure 1 Sectional view taken along the line A-A.
[0037] The retroreflective plate according to the present invention is formed such that the colored areas L1 and the reflective areas L2 alternate in a stripe shape, and a bead adhesive layer 43 and a base film 41 are formed on the colored areas L1 and the reflective area L2.
[0038] The colored area L1 includes a first protective film 25, a first thermoplastic adhesive layer 23, a first flame-retardant adhesive layer 21, a colored layer 19, a light-transmitting layer 17, and a first light-collecting layer 15. The reflective area L2 includes a second protective film The film 39, the second thermoplastic adhesive layer 37, the second flame-retardant adhesive layer 35, the reflective layer 33, and the second li...

Abstract
The invention relates to a retroreflective sheet and its manufacturing method, which comprises a colored area, a reflective area and a base film, the colored area passes through a first protective film, a first thermoplastic adhesive layer, a first flame-retardant adhesive layer, a colored layer, The light-transmitting layer and the first light-collecting layer are thus emitted to the outside, and the reflective region makes incident light through the second protective film, the second thermoplastic adhesive layer, the second flame-retardant adhesive layer, the reflective layer, and the second light-collecting layer occur. reflection.
Description
Technical field [0001] The present invention relates to a retroreflective sheet and a manufacturing method thereof (Retroreflective sheet and fabricat ing method thereof), in particular, to a retroreflective sheet and fabricat ing method thereof, which can improve the light reflection efficiency of a colored area at night so as to improve the visibility (visibility) and 其制造方法。 Its manufacturing method. Background technique [0002] A retroreflective sheet is a reflector that includes a light collecting layer and a reflective layer and makes incident light reflect as it is along the incident direction. The retro-reflective board is formed into a general board shape, and is processed into a desired shape or pattern on the main surface of the to-be-attached object, and is attached to road sign boards or firefighters’ uniforms by thermocompression bonding or tailoring methods. Select the part to improve the visibility (visibility) so that it can be easily displayed even in dark place...
