The present invention pertains to a polarizing film having a transparent layer on at least one surface of a polarizer, wherein: the polarizer contains a polyvinyl alcohol-based resin and has a thickness of 15 μm or less; the transparent layer-side of the polarizer has a compatible layer thereon having compatibility with the transparent layer; and the thickness A of the polarizer and the thickness B of the compatible layer satisfy the general formula (100×B/A)≧1. This polarizing film has crack resistance and suppresses changes in the dimensions of the polarizer.

The present invention pertains to a one-side-protected polarizing film having a protective film or films on only one surface of a polarizer, wherein: the polarizer contains a polyvinyl alcohol-based resin, and is designed to have a single-body transmittance T and a polarization degree P representing optical properties satisfying the condition of the following formula: P>−(10.sup.0.99T−42.4−1)×100 (provided that T<42.3) or P≧99.9 (provided that T≧42.3), and the polarizer and a transparent resin layer have a thickness X (μm) and a thickness Y (μm), respectively, satisfying X≦12, Y≦15, and 0.15≦(Y/X)≦3. Even when the thin-type polarizer has prescribed optical properties, this one-side-protected polarizing film is capable of suppressing the occurrence of through cracks, nano-slit-induced defects and curling.

The embodiment of the present application relates to the field of Li-ion battery and, in particular, to a thermal conductive adhesive and a secondary battery containing the thermal conductive adhesive. The thermal conductive adhesive is prepared through adding thermal conductive filling material in the hot melt adhesive system, which performs good thermal conductivity and adhering property, and can stably adhere the safety component with the cell, meanwhile transferring, via the thermal conductive adhesive, heat of the cell to the safety component rapidly, so that the safety component cuts off the circuit to protect the cell during overcharge; the thermal conductive adhesive has high initial viscosity, which increases good contact between the protection device and the cell through the adhesion, thereby reduces situations that the thermal conductive adhesive is separated from the cell due to inflation and deformation of the cell.

The invention aims to provide a method of manufacturing a carbon fiber resin tape capable of being adhered with a high adhesive strength without being pressurized at high pressure nor heated at high temperature. A method of manufacturing a carbon fiber resin tape F2 comprises: a first step of immersing a carbon fiber bundle F1 having several carbon fibers in reduced water having a negative oxidation-reduction potential to flatten the carbon fiber bundle; a second step of immersing the above-described carbon fiber bundle in an adhesive solution containing an adhesive S, alumina sol A, and potassium persulfate B after the above-described first step; and a third step of drying the above-described carbon fiber bundle after the above-described second step.

A wall covering comprising a planar substrate having a front and a back facing opposite the front and an adhesive layer that covers the back of the substrate. The adhesive layer includes a separate polymer layer, formed by a polyvinyl alcohol polymer. Wall covering for example in the form of a pre-pasted paper is readily reactivated when wet, and exhibits no blocking, while having properties of sliding, adhesion, and stripability.

A sealing film suitable for food packaging is disclosed, which adopts the following solution. The sealing film comprises, in sequence, a PET layer, a VMPET layer and a PE layer from outside to inside, wherein the PE layer comprises 100-110 parts of PE, 15-20 parts of EVA, 15-20 parts of EAA, 55-60 parts of HDPE and 10-15 parts of LLDPE in parts by mass. In this manner, the addition of HDPE and LLDPE into the PE layer is intended to enhance the tensile strength of the sealing film.
