摘要： A self-adhesive multi-layer item comprising:
1) a dorsal support DO having a top face SI1 and a bottom face SI2, 2) at least one layer of silicone release coating RC applied to the top face SI1 of the dorsal support DO and which is prepared by irradiation of a curable silicone composition C not containing any solvent and comprising, as constituents: a) at least one functionalized organopolysiloxane A b) an effective amount of at least one type I photoinitiator P of the family of acylphosphine oxide derivatives of formula (III) 3) at least one adhesive PSA, preferably at least one pressure-sensitive adhesive PSA, applied on the layer of silicone release coating, 4) a frontal support FR applied on the adhesive PSA of the component 3), and 5) optionally at least one layer of silicone release coating RC applied on the bottom face SI2 of the dorsal support DO and which is prepared by application and irradiation of said curable silicone composition C, and on this same layer, there is at least one adhesive PSA, preferably at least one pressure-sensitive adhesive PSA.

摘要： Approaches are described for coating various flexible media, such as sheets of paper, synthetic polymer (polyolefin, polyester, etc.) sheets or fabric sheets, with a silicone on high-speed rolls. For example, an efficient method is described for minimizing and/or reducing mist formation when coating flexible supports with a liquid silicone composition precursor of crosslinked coatings. The coating process can be performed using a coating device that includes a roll operating at a high speed.
