The PSA sheet comprises a substrate film and a PSA layer provided to at least one face of the substrate film. The PSA layer has a thickness of 20 m or less. The PSA sheet further comprises a coating layer that partially covers the PSA layer surface. The coating layer has a thickness less than 3 m.
DECORATIVE FILM
The object of the present invention is to provide a decorative film excellent in moldability and tensile strength; and a method for producing a three-dimensionally molded article with a decorative film. The decorative film of the present invention is used for decorating a three-dimensionally molded article. It is a decorative film comprising at least a substrate film layer and a clear layer, wherein the clear layer is made of a fluorinated polymer comprising units based on a fluoroolefin, units based on a monomer having no crosslinkable group, which is at least one member selected from the group consisting of a vinyl ether, a vinyl ester, an allyl ether, an allyl ester and a (meth)acrylic acid ester, and units having a crosslinkable group; and the content of the units based on a fluoroolefin is from 20 to 70 mol % to all units which the fluorinated polymer comprises.
METHOD FOR APPLYING DIECUTS TO SURFACES AND ALSO TEST METHOD THEREFOR
Systems and methods transfer diecuts from a liner layer to a surface. One method may transfer a diecut from the liner layer to the surface by means of an applicator, wherein a ratio of the pull-off force of the diecut from the liner layer in the z direction to the pull-off force of the diecut from the surface in the z direction is at most 0.18. The method may enable particularly reliable and firm transfer of the diecut from a diecut tape to a surface where bonding is to take place. As a result, it may be possible for the frequency of errors in the bonding of plastics parts to be relevantly reduced.
