The invention concerns a method for treating a cellulosic support to reduce the penetration of anti-adhesive agent into the support and/or to diminish its sensitivity to water. Said method consists in contacting the cellulosic support with an aqueous emulsion based on a grafted functionalised polyorganosiloxane, wherein said emulsion further contains an acrylic-type polymeric material, said polymeric material advantageously containing a styrene fraction.

Treatment of cellulose substrates

A pressure-sensitive laminate and a method for making the same, for which the release strength between an adhesive layer and a release liner can be selectively varied after the laminate has been manufactured by exposing the interface between the adhesive layer and the release liner to ultraviolet light. The invention allows the selective enhancement of release strength is specific zones, such as by use of a mask. It also allows for the manufacture of a laminate having two face sheets with no dedicated backing sheet, each face sheet acting as the backing sheet for the other.

Ultraviolet control of the release of a pressure-sensitive adhesive in contact with a silicone release liner

A breathable film cover for transparent plastic plates employed as windows and the like. A metalized plasticized polyvinyl chloride film is adhesively laminated to a polycarbonate or polyacrylate plate by means of an adhesive having a UV absorber. The plasticized PVC film allows for the escape of moisture emanating as a result of degasification of the polycarbonate or polyacrylate plates. The permeability of the PVC or polyvinyl chloride film to moisture allows the metalized plasticized polyvinyl chloride film to remain adhered to the plates without bubbles, craters or tunnels.
