Patent ID: 7205367

Claim:
A multi-layer laminate hose having a fluorocopolymer layer and a polyamide resin layer directly laminated thereto, wherein the fluorocopolymer comprises (A) polymerized units of tetrafluoroethylene and/or chlorotrifluoroethylene, (B) polymerized units of a fluoromonomer, except for tetrafluoroethylene and chlorotrifluoroethylene, and (C) polymerized units of at least one member selected from the group consisting of itaconic acid, itaconic anhydride, citraconic acid and citraconic anhydride, in which the molar ratios of polymerized units (A), (B) and (C) are respectively from 50 to 99.8 mol %, from 0.1 to 49.99 mol % and from 0.01 to 5 mol %, to the total polymerized units and which has a volume flow rate of from 0.1 to 1000 mm 3 /sec.
