Invention description
According to the present invention, a kind of transfer member of giving leather gloss character is provided here, has comprised a kind of gloss film of at least two layers of coextruded layer, and wherein internal layer is activity or gloss layer, skin is a common layer, releasably depends on described outer field carrier or substrate layer.
This gloss film preferably includes three-layer co-extruded pressure layer, and wherein internal layer has gloss character, and the middle layer is to help the common layer of film bulk character but also be that accumulation layer and one deck that one deck is used to move chemical reagent is the skin of common layer.Carrier such as paper adheres to this skin.
This internal layer comprise a kind of independent or with the resin layer of the isotatic polypropylene of content 0-40 weight % ethylene, propylene random copolymers combination.This middle layer comprises isotatic polypropylene and migration additive, and the migration additive is static inhibitor and slippage agent.This skin also comprises isotatic polypropylene and a kind of additive, and additive is a release agent.Stiffener adheres on the skin with tackiness agent such as paper.
Internal layer can comprise the migration chemical reagent in addition, and its content is 0-5%, and the migration chemical reagent is static inhibitor and slippage agent, and being selected from can be separately or erucicamide (erucamide), stearylamide, silicone oil, stearic acid and the stearate of its arbitrary combination use.In addition, internal layer can comprise a kind of release agent, and its content is 500-4000ppm.Release agent is selected from separately or silicon-dioxide, silicate, clay, talcum and the quartz of its arbitrary combination.The turbidity of internal layer or glossiness are to change by changing the quantity of moving chemical reagent and release agent in interior layer thickness, the composition.
The content of this migration chemical reagent in the middle layer that comprises described static inhibitor and slippage agent is 500-10000ppm weight.
This skin is identical with internal layer, comprises and ethylene, propylene random copolymers bonded isotatic polypropylene that therein ethylene propylene copolymer content is 0-40% weight.Film comprises that also one deck adheres to outer field ply of paper.This ply of paper is a kind of cellulose paper, such as the cromo art paper, its gram number be 30-100 gram/square metre.
The isotatic polypropylene molecular-weight average that exists in layer is 25000 to 1,000,00, and the melt flow index under 230 ℃/2.16 kilograms is 1-25g/10min, and density is 0.892-0.92g/cm
