Title:
LAMINATE AND ITS USE
Document Type and Number:
Japanese Patent JP2021154723
Kind Code:
A
Abstract:
To obtain a laminate suitable for a process paper for embossing process, which is difficult to cause surface melting, is excellent in heat resistance, and is improved in frequency in being usable repeatedly.SOLUTION: The invention relates to a laminate comprising a layer made of a composition (X) containing 4-methyl-1-pentene based polymer (A) satisfying the following requirements (A-a) to (A-c) and 0.01 to 1.0 pt.mass of a phenolic antioxidant (B) having a melting point in the range of 190 to 250°C relative to 100 pts.mass of the polymer (A) on at least one surface of a substrate layer. (A-a) The content rate of a constituent unit (P) derived from 4-methyl-1-pentene is 90 to 100 mol%, and the content ratio of a constituent unit (AQ) derived from α-olefin (4-methyl-1-pentene is removed) of carbon number of 2 to 20 is 0 to 10 mol% (however, a total of content rates of the constituent unit (P) and the constituent unit (AQ) is set to 100 mol%). (A-b) The melt flow rate (MFR) under 260°C and 5 kg load is in the range of 0.01 to 250 g/10 minutes. (A-c) The melting point (TM) measured by DSC is in the range of 200 to 250°C.SELECTED DRAWING: None
