Title
(EN) SLIPPERY METAL LAMINATE AND PROCESS FOR PRODUCING THE SAME
Abstract
(EN)
A slippery metal laminate excelling in slipperiness that in the lamination of multilayer substrate by means of a hot press, reduces the inter-film adhesion at a hinge portion, enabling elimination of any "sounding" trouble caused by inter-film friction. There is provided a metal laminate comprising a polyimide film of 0.1 to 0.7 inter-film surface static friction coefficient, preferably 0.7 to 10μm film surface roughness (Rz), having streaky unevenness on its surface as a base material and, superimposed on the backside thereof, a metal. Further, there is provided a process for producing a slippery metal laminate, characterized in that a metal laminate having a metal superimposed through an adhesive on a polyimide film on the polyimide film surface is rubbed using a grinding tape to thereby form streaky unevenness on the film surface and realize an inter-film surface static friction coefficient of 0.1 to 0.7. ©KIPO&WIPO 2009
