Abstract
The invention provides a light-transmitting cover foil intended to be arranged adheringly to a surface, for instance the surface of a carrier plate, optionally bearing information such as letters, numbers, images or the like, which foil consists of a laminate comprising: a first layer plastically deformable only at a relatively high first temperature, for instance in the range of 120.degree. C.-200.degree. C. and comprising for instance polycarbonate, PMMA, PVC, ABS, PP, PE, which first layer is provided before, during or after joining together to the other layers with a structure, for instance a texture and/or pattern pressed out of its main surface by exerting pressure and increasing temperature to at least the said first temperature, for instance by applying a heated profile roller; a second layer adhered thereto consisting of a dimensionally stable carrier layer comprising for instance polycarbonate, PMMA, PVC, polyester/PET, ABS; and a third layer adhered thereto which is meltable and thus thermally-activated at a relatively low second temperature, for instance in the range of 50.degree. C.-90.degree. C. and which consists of a hot-melt layer or glue layer, comprising for instance EVA, EEA, EBA, EMA, GBA or other low-melting plastics including polyolefins and copolymer esters, polyacetate esters, softened PVCs; which said layers are mutually connected by adhesive agents, for instance by making use of coextrusion.
Description
But the present invention relates to a kind of transmitted light, as transparent face paper tinsel, this face paper tinsel is used to adhere to the surface of carrying information not necessarily.
This paper tinsel is known, this known face paper tinsel comprise the ground floor formed by polyester be connected thereon pressure-sensitive or the glue-line of thermal activation.
An object of the present invention is to provide a kind of paper tinsel, it can provide the combination of two aspects, promptly has the ground floor of certain structure and a kind of glue-line of thermal activation.When glue-line is activated, existing structure is not had a negative impact.
Described known paper tinsel layer does not satisfy these requirements.
Therefore, an object of the present invention is to provide the face paper tinsel of light-permeable, it has certain structure, texture and/or the pattern that extrudes at its first type surface for example, also require to satisfy use simple mode that the face paper tinsel is adhered to a surface simultaneously and go up with it covering, and the structure of existence is not had a negative impact.
From the above, the invention provides a kind of face paper tinsel that is used to stick at a lip-deep light-permeable, this surface for example is the surface of board, and this surface is carrying information not necessarily, and as letter, numeral, image etc., this paper tinsel is by comprising that the sandwich construction with lower floor constitutes:
Ground floor, this layer is only in first kind of high relatively temperature, produce plastic deformation as 120 ℃-200 ℃, and comprise for example Merlon, PMMA, PVC, ABS, PP, PE, this ground floor can be before it be connected to other layer, make a kind of structure during this time or afterwards, this structure example is in this way by exerting pressure and be warming up to described at least first temperature, for example texture and/or the pattern that extrudes by the knurling rolls that use heating on its first type surface.
Adhere to the second layer on it, constitute, for example comprise Merlon, PMMA, PVC, polyester/PET, ABS by the bearing bed of a dimensionally stable; With
Adhere to the 3rd layer on it, this layer is fusible, therefore under second kind of low relatively temperature, for example can be under 50 ℃-90 ℃ by thermal activation, and this layer comprises a heat fusing layer or a glue-line, for example comprise EVA, EEA, EBA, EMA, GBA or other low melt plastics, comprise polyolefin and copolyesters, poly-acetate, softening PVC;
The above each layer interconnects by adhesive, for example by using the coextrusion method to interconnect.
Should note not using the material of polyester/PET as ground floor.
The present invention is based on following opinion: the structure of ground floor can be made in advance, because the high relatively softening temperature of material therefor, for example at 180 ℃ of orders of magnitude, when glue-line at for example 70 ℃ down during activation, the ground floor that comprises described structure is unaffected, and glue-line by fully the activation face paper tinsel can be adhered on the surface that is capped effectively.
For example the second layer that constitutes by polyester be to a great extent non-retractility with non-shrinking.This layer also makes heating surface paper tinsel band in the lamination machine and can not cause the situation of the whole deliquescing of face paper tinsel to become possibility that the whole deliquescing meeting of face paper tinsel wherein limits the easiness of its processing.
Specific embodiment has concrete feature, and promptly the ground floor and the second layer are made of the basic layer uniformly of holistic chemical property.Also note that and do not adopt the material of polyester as ground floor.In this case, the multilayer that combines also so not comprises polyester/PET material.
Specific embodiment has concrete feature, and promptly adhesive comprises at least the activation in the enhancing viscosity of gluing surface, and sided corona treatment for example is especially under polyester and polyacrylic situation.The processing that other is relevant, bombardment also is suitable for as ion.
Bonding between different layers can be carried out in principle by any way.Specific embodiment is that wherein adhesive comprises an adhesive layer, as is adhered to the primer layer that is used for two gluing surfaces.
All suitable manner all can consider to be used to provide the ground floor that has certain structure.Specific embodiment is wherein in advance ground floor to be provided certain structure by machinery, chemistry and/or physical treatment or with the cover layer that can form certain structure, for example by modes such as steam sedimentation, spraying platings.
Usually, first and the 3rd layer softening temperature must have evident difference, for example at least 30 ℃ the order of magnitude.Under any circumstance, when face paper tinsel heating is gone up so that it is covered to adhere to a surface, the structure of ground floor should not be adversely affected.
In order to ensure good UV stability, this sandwich construction in position can comprise anti-UV layer, for example an enamelled coating.
