Abstract
To provide a laminate excellent in alkali resistance and interlaminar strength at high temperature, and a process for producing the laminate. A process for producing a laminate, comprising producing a non-crosslinked laminate having a layer of a first composition containing a copolymer having fluorine atoms and a layer of a second composition containing a non-fluorinated elastic polymer, and crosslinking the first composition and the second composition to produce a laminate having a first layer formed of a crosslinked product of the first composition and a second layer formed of a crosslinked product of the second composition, wherein when the first composition and the second composition contains a common crosslinking aid, the absolute value of the crosslinking rate difference between the first composition and the second composition is at most 0.30.
