| 摘要 |
THE INVENTION IS CONCERNED WITH A PRESSURE SENSITIVE ADHESIVE SHEET COMPRISING A SUBSTRATE AND, SUPERIMPOSED THEREON, A PRESSURE SENSITIVE ADHESIVE LAYER, SAID SUBSTRATE EXHIBITING A MAXIMUM VALUE OF DYNAMIC VISCOELASTICITY TAN ( ) OF AT LEAST 0.5 AT A TEMPERATURE RANGING FROM -5 TO 80°C. AT THE TIME OF WORKING OF THE BACK OF AN ADHEREND HAVING A SURFACE WHOSE IRREGULARITY HEIGHT DIFFERENCES ARE LARGE, THIS PRESSURE SENSITIVE ADHESIVE SHEET IS PREFERABLY STUCK TO THE ADHEREND SURFACE TO THEREBY PROTECT IT DURING THE WORKING. |
