PRESSURE-SENSITIVE ADHESIVE COMPOSITION AND PRESSURE-SENSITIVE ADHESIVE SHEET

摘要

The present invention provides a pressure-sensitive adhesive composition comprising a base polymer and a tackifier resin. The base polymer is a block copolymer of a mono-vinyl-substituted aromatic compound and a conjugated diene compound. The tackifier resin comprises a low softening point resin having a softening point below 120° C. and a high softening point resin having a softening point of 120° C. or above. The high softening point resin comprises a terpene-phenol resin.
