Pressure-sensitive transferring protective covering material and method
for protecting and covering a print formed of a dye on an object with
the use of said material
摘要:
A pressure-sensitive transferring protective covering material comprising at least (a) first flexible substrate, (b) an adhesive layer, (c) a solid resin layer, and (d) a second flexible substrate which are stacked in the named order, wherein said first flexible substrate (a) has a peel force of 30 g/inch to 120 g/inch against said adhesive layer (b), said adhesive layer (b) contains a hindered amine series light stabilizer and has a cohesion of 500 g/inch to 1500 g/inch, said solid resin layer (c) comprises a transparent resin layer containing a ultraviolet absorber and having a glass transition temperature of 50.degree. C. or above, and said second flexible substrate (d) has a peel force of 120 g/inch to 400 g/inch against said solid resin layer (c).A method for protecting and covering a print formed on an object using said pressure-sensitive transferring protective covering material.
