Abstract

Provided is a protective sheet for a coating layer comprising a substrate sheet and provided thereon a pressure-sensitive adhesive layer, which can be applied as well to a coated surface insufficiently cured immediately after dried, and the pressure-sensitive adhesive layer described above comprises an addition reaction type silicone-based pressure-sensitive adhesive.

Claims

exact text as granted — not AI-modified
1 . A protective sheet for a coating layer comprising a substrate sheet and provided thereon a pressure-sensitive adhesive layer, wherein the pressure-sensitive adhesive layer comprises an addition reaction type silicone-based pressure-sensitive adhesive. 
     
     
         2 . The protective sheet as claimed in  claim 1 , wherein the addition reaction type silicone-based pressure-sensitive adhesive further comprises a curing catalyst. 
     
     
         3 . The protective sheet as claimed in  claim 2 , wherein the curing catalyst is a platinum-based catalyst. 
     
     
         4 . The protective sheet as claimed in  claim 1 , wherein the substrate sheet is a polyethylene terephthalate sheet. 
     
     
         5 . The protective sheet as claimed in  claim 1 , wherein the pressure-sensitive adhesive layer is cross-linked by heating or irradiating with an active energy beam. 
     
     
         6 . The protective sheet as claimed in  claim 1 , wherein a said protective sheet for a coating layer is applied on cars. 
     
     
         7 . The protective sheet as claimed in  claim 1 , wherein a said protective sheet for a urethane-based coating layer is applied on resin-made bumpers. 
     
     
         8 . The protective sheet as claimed in  claim 2 , wherein the substrate sheet is a polyethylene terephthalate sheet. 
     
     
         9 . The protective sheet as claimed in  claim 2 , wherein the pressure-sensitive adhesive layer is cross-linked by heating or irradiating with an active energy beam. 
     
     
         10 . The protective sheet as claimed in  claim 2 , wherein said protective sheet for a coating layer is applied on cars. 
     
     
         11 . The protective sheet as claimed in  claim 2 , wherein said protective sheet for a urethane-based coating layer is applied on resin-made bumpers.
