PRESSURE-SENSITIVE ADHESIVE MEMBER AND LIGHT SOURCE UNIT

摘要

PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive member and a light source unit capable of easily and freely converting a light irradiated from a light source to a light having an aimed optional color tone.

SOLUTION: The pressure-sensitive adhesive member is excited with an ultraviolet ray having a peak wave length range of 280-420 nm and contains at least two fluorescent materials different from the ultraviolet ray peak wave length and outputs a visible light having peak wave range of 380-780 nm and contains plural fluorescent materials formed with an acrylic pressure-sensitive adhesive material containing co-polymerizable monomer component having a 1-18C alkyl (meth)acrylate and a functional group. The pressure-sensitive adhesive material is preferably further contains an ultraviolet ray absorbent layer.
