Separating membrane of plastic material, made up of a bossed and waterproof sheet which is coupled with a permeable base layer. The bosses are of the cylindrical type with a double diameter and have such a shape and arrangement as to feature improved adhesion on both faces. The gripping of the adhesive is increased in order to obtain greater tear strength, on the upper face, and at the same time increases the area of contact with the base layer for a greater resistance to delamination on the lower face. In particular, inside each chamber there is an internal crown, which divides it like a necking into two superimposed compartments having the same diameter, wherein the first compartment has a depth amounting to at least ⅓ of the total. A production process for obtaining the membrane is also disclosed.

To provide a laminate having characteristics of a fluorinated polymer film such as weather resistance and stain resistance, and having an increased solar reflectance by a light reflection layer, wherein the solar reflectance is less likely to decrease over a long period of time, and the light reflection layer is less likely to delaminate; and a production process thereof.

A laminate 1 comprising a substrate 10 containing a first fluorinated polymer, a light reflection layer 12 made of a non-curable resin composition containing a second fluorinated polymer and an aluminum pigment, and a protective layer 14 obtained by curing a curable resin composition containing a third fluorinated polymer having a crosslinkable group and a curing agent for curing the third fluorinated polymer, wherein the light reflection layer 12 is disposed between the substrate 10 and the protective layer 14, the light reflection layer 12 has a thickness of from 0.5 to 5 μm, and the protective layer 14 has a thickness of from 0.3 to 2 μm.

The invention relates to a novel binder system and its use for bonding textile fabrics as well as products containing such bonded textile fabrics.
