A polymer film comprises a polymer composition containing (A) a cyclic olefin polymer containing an olefin unit having a C.sub.3-10alkyl group as a side chain thereof and (B) a chlorine-containing polymer. The chlorine-containing polymer (B) may comprise a vinylidene chloride-series polymer. The ratio of the chlorine-containing polymer (B) relative to 100 parts by weight of the cyclic olefin polymer (A) may be 0.5 to 60 parts by weight. The film has a moderate releasability from an electrolyte membrane and an electrode membrane of a polymer electrolyte fuel cell and a moderate adhesion to the electrolyte membrane and the electrode membrane and can adhere to a commonly-used substrate film without interposition of an adhesive layer such as an easily adhesive layer. The film is thus suitable as a release film for producing a membrane electrode assembly of a polymer electrolyte fuel cell.

The present disclosure is directed to laser-markable insulation material and cable or wire assemblies containing such insulation material. In certain embodiments, the laser-markable insulation material can include a fluoropolymer and an inorganic laser-markable pigment. The pigment can have a mean crystal size in a range of about 0.4 microns to about 2 microns and/or a median particle size (d.sub.50) in a range of about 0.45 microns to about 2 microns. The insulation material can exhibit improved initial and heat-aged contrast ratios without diminishing the ability of a cable or wire containing the insulation material to meet industry standards for electric-arc tracking and propagation resistance.
