The present invention provides a layered body for organic electroluminescence which is excellent in the hardness, the transparency and the folding-durable performance. The present invention is a layered body for organic electroluminescence in which an optical layered body is laminated on one surface of an organic electroluminescence layer and which is not cracked or fractured when a test in which the entire area of the layered body for organic electroluminescence is folded 180 degrees at 20 mm intervals is repeated 100,000 times.

Layered body for optical member and image display device

The invention provides a gas barrier film with low deterioration in the gas barrier property before and after high-temperature hot water treatment. The gas barrier film has a gas barrier coating film, formed as a composite film comprising a network structure having a mesh structure with Si&#x2014;O&#x2014;Si bonds as the basic lattice and a water-soluble polymer crystallized as microcrystals, incorporated into the mesh of the network structure, wherein a barrier coating agent, obtained by mixing a condensate solution of an alkoxysilane hydrolysate prepared as a mixed solution in which the proportion of bonded states of the silicon atoms of the condensate with Q1 and Q2 structures is at least 60% of the total silicon atoms, with a crystalline water-soluble polymer, is coated on a base material film, either after forming or without forming an aluminum oxide vapor deposition film, to form a coating layer.

Gas barrier film and method for producing it

An optical layered body that can reduce the occurrence of curling and has excellent workability when being affixed to a polarizing element or a display panel is provided. In particular is provided an optical layered body having a hard coat layer on one side of a triacetylcellulose substrate, wherein a Martens hardness (N1) of the surface of the hard coat layer, a Martens hardness (N2) of the center of the cross-section of the hard coat layer, and a Martens hardness (N3) of the center of the cross-section of a triacetylcellulose substrate as measured by nanoindentation at a load of 10 mN are as follows: the Martens hardness (N1) is 200 to 450 N/mm; the Martens hardness (N2) is 100 to 300 N/mm; and the Martens hardness (N3) is 150 to 250 N/mm.

Optical layered body, polarizer, and image display device

The present invention provides an optical layered body having excellent hardness, abrasion resistance, and flexibility. The present invention provides an optical layered body having a hard coat layer on one side of a triacetylcellulose substrate, wherein a Martens hardness (N) of a surface of the hard coat layer, a Martens hardness (N) of the center of the cross-section of the hard coat layer, and a Martens hardness (N) of the center of the cross-section of the triacetylcellulose substrate have a relationship of N&#x3e;N&#x3e;Nas determined by nanoindentation, and the hard coat layer has a pencil hardness of 4H or more as measured by a test in accordance with a pencil hardness test defined in JIS K5600-5-4 (1999) at a load of 4.9 N.

Intended is to provide an electromagnetic shielding material having a conductive layer pattern by transferring a conductive composite to a transparent base material, and an electromagnetic shielding material having a metal layer formed on the transferred conductive layer. The electromagnetic shielding material is free from the troubles such as the breaking of wire, the non-conforming shape or the low contact, which is based on the non-conforming transfer of the conductive composite. The electromagnetic shielding material comprises a transparent base material, a primer layer formed over the transparent base material, and a conductive layer formed in a predetermined pattern on the primer layer. In the primer layer, a portion having the conductive layer formed therein has a thickness larger than the thickness of a portion without the conductive layer.
