Abstract: A method for manufacturing a retroreflective sheet, provided with a retroreflective layer having retroreflective elements on one surface, a back face layer provided to face the retroreflective elements, a coupling portion to couple a part of the retroreflective elements and a part of the back face layer, the method including a preparation step of preparing a resin composition that has a viscosity capable of adhering over a predetermined time after application of predetermined energy, and completes curing after the predetermined time passes, a coating step of applying the resin composition forming the coupling portion on the retroreflective layer or the back face layer, an energy application step of applying the predetermined energy to the resin composition, and a bonding step of bonding the retroreflective layer and the back face layer via the resin composition to which the predetermined energy is applied before the predetermined time passes.

Abstract: A retroreflective sheet includes: a retroreflective layer (20) including a plurality of retroreflective elements (24) on one surface; a back face layer (40) provided to face the surface of the retroreflective layer (20) on the side of the retroreflective elements (24) and including a bonding portion (42) bonded to the retroreflective elements (24); and a plurality of particles (30) disposed between the retroreflective elements (24) and the back face layer (40). The bonding portion (42) is continuously formed to surround a plurality of capsule portions (46) in plan view. Voids (32) are formed between the retroreflective elements (24) and the back face layer (40) in the plurality of capsule portions (46).

Abstract: A retro-reflective sheet includes: a retro-reflective layer (20) including a plurality of retro-reflective elements (24) on one surface; and a back face layer (30) provided to face the surface of the retro-reflective layer on the retro-reflective elements side. A part of the retro-reflective layer and a part of the back face layer are bonded to each other via a coupling portion (34) colored in a color other than white. Voids (36) are formed between another part of the retro-reflective layer and another part of the back face layer. The color of the coupling portion is different from colors of layers provided on a side opposite to the back face layer side from the voids.
