Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an ultraviolet absorbing adhesive and an ultraviolet absorbing adhesive sheet capable of efficiently cutting light having about 380-410 nm wavelength which can not be cut by an ultraviolet light absorbent in which a fluorescent brightening agent is formulated and capable of retaining transparent appearance even when stored under hot humid environment. SOLUTION: A copolymer composition is obtained by copolymerizing an alkyl (meth)acrylate monomer having a 2-12C alkyl group part with an ultraviolet absorbing monomer as a monomer component. The ultraviolet absorbing adhesive is obtained by formulating the copolymer composition with a fluorescent brightening agent. COPYRIGHT: (C)2005,JPO&NCIPI
