         9 . The nail sticker using a rear print according to  claim 1 , further comprising a three-dimensional decoration formed on a surface of the substrate which is opposite to the surface thereof to which the print layer is printed. 
     
     
         10 . The nail sticker using a rear print according to  claim 1 ,
 wherein the print layer is printed by using a roll coater, a bar coater, or a screen printing.   
     
     
         11 . The nail sticker using a rear print according to  claim 1 ,
 wherein the print layer is formed by mixing the light-reflective particles with any one of acryl-based resins, urethane-based resins, and combinations thereof.   
     
     
         12 . The nail sticker using a rear print according to  claim 11 ,
 wherein the light-reflective particles are mixed with any one of the acryl-based resins, the urethane-based resins, and combinations thereof by means of screen printing, scattering, or spraying.   
     
     
         13 . A method for manufacturing a nail sticker using a rear print, comprising:
 (A) printing a print layer having light-reflective particles to a substrate made of polyurethane;   (B) forming an adhesive layer on the print layer; and   (C) forming a release layer on the adhesive layer.   
     
     
         14 . The method for manufacturing a nail sticker using a rear print according to  claim 13 ,
 wherein in the step (A), the light-reflective particles include glitter, bling, spangle, confetti, or pearl.   
     
     
         15 . The method for manufacturing a nail sticker using a rear print according to  claim 13 , before the step (A), further comprising:
 treating one surface of the substrate to which the print layer is to be printed is treated, by means of acryl-based primer, urethane-based primer, plasma treatment, or corona treatment.   
     
     
         16 . The method for manufacturing a nail sticker using a rear print according to  claim 13 ,
 wherein after the release layer is removed, when the adhesive layer is adhered to a nail, the adhesive layer, the print layer, and the substrate are disposed in order from the nail.   
     
     
         17 . The method for manufacturing a nail sticker using a rear print according to  claim 13 ,
