Methods for applying a liner-free, or liner-less label, to a substrate, particularly glass or plastic (e.g., PET) substrates are described herein. The method includes applying an adhesive composition, such as a polymeric coating, to a label face sheet, activating the adhesive composition with an activating fluid, and contacting the label to the substrate. The activating fluid is preferably a mixture of water and one or more organic solvents, such as low molecular weight alcohols. In some embodiments, the labels exhibit a percent fiber tear greater than about 50, 55, 60, 65, 70, 75, 80, 85, 90, or 95% after one, two, three, four, or five minutes. In particular embodiments, the labels exhibits a percent fiber tear greater than 60, 65, 70, 75, 80, 85, 90, or 95% after two minutes.

A temporary bonding laminate for use in the manufacture of semiconductor devices and a method for manufacturing semiconductor devices are provided. A member to be processed (a semiconductor wafer or the like) can be temporarily supported securely and readily during a mechanical or chemical process of the member, and then the processed member can be readily released from the temporary support without damaging the processed member even after a high temperature process. The laminate includes: (A) a release layer and (B) an adhesive layer. The release layer contains (a1) a compound being liquid at 25° C. and having a 5% mass reduction temperature of 250° C. or more when measured in a nitrogen gas stream under heating conditions of a constant heating rate of 20° C./min; and (a2) a binder having a 5% mass reduction temperature of 250° C. or more when measured under the same conditions.

摘要:
Fluid activatable adhesive compositions and activating fluid(s) for activating the adhesive composition are described herein. The adhesive compositions contain at least two polymers with different hydrophilicities. The hydrophilic polymer has quick tack when exposed to a hydrophilic solvent, such as water or other aqueous solvent, while the hydrophobic polymer provides strong adhesion to a paper or polymeric substrate. The adhesive composition may contain particulate fillers which enable fast exhaustion of the activation fluid out of the adhesive when applied to a substrate, thereby allowing the hydrophobic polymers of the adhesive composition to achieve strong adhesion of the liner-free label to the paper or polymeric substrate. The particulate fillers may also function as anti-blocking agents when liner-free label media are tightly wound in a roll. The adhesive compositions described herein may be used not only on paper, cardboard, and metal, but also on glass and plastics commonly used in commercial applications.
