Zusammenfassung:PROBLEM TO BE SOLVED: To provide a laminated structure which is prevented from being deteriorated with the elapse of time during use and separated efficiently and certainly at the time of recovery, and a separation and recovery method therefor. SOLUTION: A heating releasable coating layer is provided between the hard plate and foamed resin heat insulating material layer of the laminated structure. The heating releasable coating is based on organic emulsion coating and contains 3-15 wt.% of thermally expansible hollow fine particles and 5-10 wt.% of an aqueous isocyanate. Further, the coating amount per a unit area of the heating releasable coating is 100-300 g/m2. COPYRIGHT: (C)2004,JPO
