摘要： To provide a dispersion, a laminate, a film and an impregnated woven fabric.
A powder dispersion comprising powder I of polymer I having units based on tetrafluoroethylene and an oxygen-containing polar group, powder II of polymer II containing units based on a fluoroolefin, a dispersing agent, and a liquid dispersion medium, wherein the ratio of the mass content of the polymer I to the mass content of the polymer II is at most 0.7, or such a power dispersion wherein the dispersing agent is a fluorinated surfactant having a hydroxy group. A laminate, a film, and an impregnated woven fabric produced by using such a powder dispersion.

摘要： The purpose of the present invention is to provide a fluororesin film or fluororesin laminate excellent in heat resistance and excellent in interlayer adhesion to an object to be laminated, such as a prepreg, a method for producing a hot pressed laminate using said film or laminate, and a method for producing a printed circuit board. The fluororesin film contains a fluororesin having a melting point of from 260 to 380° C., and has an arithmetic average roughness Ra of at least 3.0 nm when inside of 1 μm2 of at least one surface thereof in the thickness direction is measured by an atomic force microscope. The laminate 1 has a layer A10 containing said fluororesin and a layer B12 made of another substrate, wherein the layer A10 has an arithmetic average roughness Ra of at least 3.0 nm when inside of 1 μm2 of a second surface 10b thereof is measured by an atomic force microscope.
