<p>PURPOSE: A method for manufacturing a retro-reflective sheet is provided to prevent separation of a light reflective member from a body and to simply form the light reflective member in a reflective area of a colored layer. CONSTITUTION: A bead alignment layer(49) is formed on a carrier film(47). A light concentrating layer(41) is formed on the bead alignment layer in which a mask tape is formed. A plurality of beads(39) is formed in the light concentrating layer. The mask tape is eliminated. The mask tape is extended and attached to a non-reflective area on a colored layer(35) as a stripe shape. A bonding layer(33) is formed on the colored layer. The carrier film is eliminated.</p> |
