Abrégé

The present invention relates to a cube corner type retroreflection sheet. Provided are a cube corner type retroreflection sheet and a manufacturing method therefor, the sheet comprising: a base layer; a printing layer disposed on one side of the base layer; a plurality of cube corner elements which are coupled to the printed layer and of which each has a flat observation surface provided on one surface of the printed layer and a structural surface provided on the other side thereof; and an adhesive layer coupled to the cube corner element so that a portion of the structure surface of the cube corner element is embedded therein, and thus the present invention can improve a whiteness index, and reduce halation by absorbing infrared rays.

Disclosed are a light-reflecting strip and a method for manufacturing same. The light-reflecting strip, according to one embodiment, comprises: a reflective tape that reflects incident light and includes a plurality of layers; and a detachable film that covers the entire attachment surface of the reflective tape. The width of the film is greater than the width of the reflective tape, the film includes a portion extending beyond the reflective tape, and the extended portion is provided in line with the reflective tape in the longitudinal direction of the reflective tape.

Disclosed is a retroreflective sheet using a cube-corner type retroref lection principle, which is composed of a body layer which includes a flexible transparent thermoplastic sheet made of a transparent material for high light transmittance and having a smooth surface as a reflective surface and also includes a woven fabric disposed therein, and a cube -corner type microprism layer having a retroreflective function formed on a surface of the body layer including the transparent thermoplastic sheet and the woven fabric in an integrated form, opposite the reflective surface. The retroreflective sheet has a configuration in which the woven fabric having high tensile strength is inserted into the transparent thermoplastic polymer (PVC, TPU, PO, or acryl) sheet, and is suitable for end uses requiring high tensile force.

Abrégé

The object of this invention is to provide a method of manufacturing a cube-corner type retroreflective element and a cube-corner type retroreflective element manufactured thereby. The method of the current invention includes (a) laminating a thermosetting resin having a predetermined thickness on an upper surface of a base film (200) , and then forming a plurality of triangular pyramidal cube- corner type ret roref lectors (101) , each of which has three congruent surfaces, other than a retroreflective surface attached to the base film; (b) coating the three surfaces, other than the retroreflective surface, of each of the plurality of cube-corner type retroreflectors (101) formed on the base film (200) with a metal film (C) having a predetermined thickness, to manufacture a plurality of cube-corner type retroreflective elements (100) ; and (c) stripping the cube-corner type retroreflective elements (100) from the base film (200) , and then individually collecting the cube-corner type retroreflective elements.
