摘要： NORMALLY TACKY PRESSURE-SENSITIVE ADHESIVES AND ADHESIVE TAPES HAVING EXCELLENT SHEAR STRENGTH AND CREEP RESISTANCE, PARTICULARLY AT ELEVATED TEMPERATURES, TOGETHER WITH GOOD PEEL STRENGTH AND TACK PROPERTIES, ARE OBTAINED BY COMBINING TACKIFYING RESIN WITH LOW MOLECULAR WEIGHT A-B BLOCK COPOLYMER. THE COPOLYMER A BLOCK IS NORMOLLY GLASSY AND HAS A GLASS TRANSITION TEMPERATURE ABOVE 75*C. WHILE THE COPOLYMER B BLOCK IS AMORPHOUS AND ELASTOMERIC AT TEMPERATURES ABOVE -20*C. SHEAR STRENGTH OF THE ADHESIVE MAY BE INCREASED BY ADDITION OF BLOCK COPOLYMERS CONTAINING THREE OR MORE BLOCKS.

摘要： An adhesive tape is used for fixing a member constituting an electronic apparatus and includes an adhesive layer (A) and a base material (B). The adhesive layer (A) contains an adhesive containing a styrene-based block copolymer and an adhesiveness-imparting resin. The adhesive has a Trouton ratio of 3 or more and 90 or less when the adhesive composition is made into a toluene solution having a solid concentration of 25% (w/w) and is subjected to measurement at 35° C.
