An adhesive composition for temporarily attaching a substrate to a support plate which supports the substrate, and includes a thermoplastic resin and a release agent.

The present invention provides a hard coating film having excellent optical characteristics and adhesion of a hard coating layer, and having excellent adhesion to a laminated film formed on the hard coating film.

The hard coating film comprises a hard coating layer containing an ionizing radiation curable resin composition provided on at least one surface of a base film, the hard coating film satisfying the following conditions (I), (II), and (III): condition (I): the ionizing radiation curable resin composition comprising an acrylic resin containing a (meth)acryloyl group; condition (II): a peak area ratio 1 ((A/B)100) of 5% or more (provided that in infrared spectrum measurement of the ionizing radiation curable resin composition in an uncured state, a peak area appearing at 3250 to 3500 cm.sup.1 is defined as A, and a peak area appearing at 1650 to 1800 cm.sup.1 is defined as B); and condition (III): a peak area ratio 2 ((C/B)100) of 30% or less (provided that in infrared spectrum measurement of the ionizing radiation curable resin composition in an uncured state, a peak area appearing at 1500 to 1580 cm.sup.1 is defined as C, and a peak area appearing at 1650 to 1800 cm.sup.1 is defined as B).

A method of preparing a glazing, comprising: stacking a first glass sheet, a first interlayer, a photopolymer film, a second interlayer, and a second glass sheet to provide a lamination stack; deairing the lamination stack; autoclaving the lamination stack to provide a laminated glazing; applying a reactive light to the photopolymer film in the laminated glazing, wherein reactive light is applied to the laminated glazing through a master holographic film; and bleaching the laminated glazing such that the photopolymer film is no longer reactive to light exposure.

The specification relates to a heat-removable label (1) comprising a face layer (2) and an adhesive layer (4), wherein the adhesive layer (4) comprises pressure sensitive adhesive and a heat-activatable filler. The heat-activatable filler is capable of reducing adhesion of the heat-removable label (1) when being activated, and the heat-removable label (1) is detachable from a surface of an item by exposing the heat-removable label adhered to the surface of the item to heat such that at the time of detachment, effective temperature experienced by the adhesive layer is at least 80 degrees C. or more, the effective temperature being such that mechanical recyclability of material(s) of the face layer and/or the item is not endangered. Further, the specification relates to a label laminate and a linerless label web for providing the heat-removable label, as well as to uses of such. Still further, the specification concerns a combination of a heat-removable label and an item, as well as a method for removing a heat-removable label from a surface labelled, a method for manufacturing a label laminate and a method for manufacturing a linerless label web.

The invention provides a diaphragm for a microspeaker and a manufacturing method thereof. The diaphragm is a single-layer diaphragm or a multi-layer diaphragm and comprises at least one layer of a chemically cross-linked thermoplastic polyester elastomer, wherein: the chemically cross-linked thermoplastic polyester elastomer has a loss factor less than or equal to 0.4 at a temperature range not higher than a softening temperature of thermoplastic polyester elastomer before chemical crosslinking plus 40 C., as measured by a rheological curve; and the diaphragm further has a yield strain in the range of 7% to 30%. The diaphragm for a microspeaker according to the technical solution of the present invention is easy to be prepared by thermoforming, and has appropriate modulus, good strength, elasticity, and thermal stability.

An electronic apparatus includes a window, a display panel disposed below the window, and a digitizer disposed below the display panel. The digitizer includes a base layer having a first surface and a second surface opposing the first surface, a first sensing coil disposed on the first surface of the base layer, a second sensing coil disposed on the second surface of the base layer, a first adhesive layer disposed on the first sensing coil, and a second adhesive layer disposed on the second sensing coil. The first adhesive layer and the second adhesive layer are multi-curing adhesive layers.
