Beschreibung
Zusammenfassung:	This temperature-sensitive adhesive contains: a side-chain crystalline polymer having a melting point of 20-30 DEG C, obtained by adding a metal chelate compound in the addition amount (A) to a copolymer and performing a crosslinking reaction; and a tackifying agent; and the adhesive force of the temperature-sensitive adhesive decreases at a temperature less than the melting point. Copolymer: a copolymer obtained by polymerizing 25-30 parts by weight of a (meth)acrylate having a C16-22 straight-chain alkyl group, 60-65 parts by weight of a (meth)acrylate having a C1-6 alkyl group, 1-10 parts by weight of a polar monomer, and 1-10 parts by weight of a reactive fluorine compound. Addition amount (A): 3-10 parts by weight with respect to 100 parts by weight of the copolymer.
