HEAT-SENSITIVE ADHESIVE SHEET AND INFORMATION RECORDING PRODUCT USING THE SAME |
摘要 |
PROBLEM TO BE SOLVED: To provide a heat-sensitive adhesive sheet having high heat-sensitive adhesivity to an information recording surface and enabling a postcard to be given more transmitted information without destructing recorded information, and to provide an information recording product having good unsealability and functioning as a confidential postcard with good information legibility. SOLUTION: This heat-sensitive adhesive sheet for use in the heat-sensitive bonding between the information recording surfaces of respective recording materials is such one that heat-sensitive adhesive layers 60-85°C in melt flow temperature (MFT) are formed on both sides of a substrate having a release layer on one side, respectively; wherein the 180°peel strength at the interface between the substrate and the release layer is adjusted to 20-150 g/50 mm at a peel rate of 500 mm/min at 23°C and 50% RH.
