To provide a glass resin laminate of the present invention, in which the glass substrate and the resin layer containing a TFE polymer are strongly laminated, is hardly warped and is excellent in the electrical properties, a composite laminate further having a metal foil, and methods for producing them. A glass resin laminate comprising a glass substratehaving an uneven surfacewith an arithmetic mean roughness of at least 5 nm, and a resin layer containing a tetrafluoroethylene polymer in contact with the uneven surface

Glass resin laminate, composite laminate, and manufacturing method thereof

Provided is a long laminate for a printed wiring board, which has reduced thickness of a resin layer and increased signal transmission speed, and which, while being excellent in dimensional stability and folding endurance, has no wrinkles in a fluororesin layer. The long laminate contains a metal layer of a long metal foil, a fluororesin layer containing a fluororesin and contacting the metal layer, and a heat-resistant resin layer containing a heat-resistant resin and contacting the fluororesin layer. Each fluororesin layer is 1 to 10 &#x3bc;m thick. The ratio of the total thickness of the fluororesin layer to the total thickness of the heat-resistant resin layer is 0.3 to 3.0. The sum of the total thickness of the fluororesin layer and the total thickness of the heat-resistant resin layer is at most 50 &#x3bc;m. Also provided are a method for producing the long laminate, and the printed wiring board.

Long laminate, method for its production and printed wiring board

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&#xb0; C., and has an arithmetic average roughness Ra of at least 3.0 nm when inside of 1 &#x3bc;mof at least one surface thereof in the thickness direction is measured by an atomic force microscope. The laminatehas a layer Acontaining said fluororesin and a layer Bmade of another substrate, wherein the layer Ahas an arithmetic average roughness Ra of at least 3.0 nm when inside of 1 &#x3bc;mof a second surfacethereof is measured by an atomic force microscope.

Fluororesin film and laminate, and method for producing hot pressed laminate

To provide a liquid composition whereby a resin powder can be uniformly dispersed in a resin or the like without being scattered, and a method for producing a film, a laminate or the like by using the liquid composition. The liquid composition comprises a liquid medium and a resin powder dispersed in the liquid medium, and characterized in that the average particle size of the resin powder is from 0.3 to 6 &#x3bc;m, the volume-based cumulative 90% diameter of the resin powder is at most 8 &#x3bc;m, and the resin powder is a resin containing a fluorinated copolymer having a specific functional group. And, the method is a method for producing a film, a laminate or the like by using the liquid composition.
