Abstract: A low dielectric resin composition comprises a low dielectric resin containing acid anhydride, an epoxy resin, a rigid cross-linking agent, a soft cross-linking agent, and an accelerator. Such low dielectric resin can be dissolved in organic solvent more easily than a low dielectric resin without acid anhydride, and the low dielectric resin containing acid anhydride has a better compatibility with other organic components than a low dielectric resin without acid anhydride. A low dielectric resin composition with lower dielectric constant and better properties can thus be obtained. A film and a circuit board using such resin composition are also provided.

Abstract: The present invention aims to provide a luminescent sheet capable of displaying high-luminance images under irradiation with light and capable of controlling the adhesion to glass, and an interlayer film for a laminated glass and a laminated glass each including the luminescent sheet. Provided is a luminescent sheet including: a thermoplastic resin; a luminescent material; and a cyclic coordination metal compound having a five- or more-membered ring structure formed by coordinating an organic compound having in a molecule two or more atoms of at least one kind selected from oxygen, phosphor, nitrogen, and sulfur, to at least one metal selected from an alkali metal, an alkaline earth metal, and magnesium.
Abstract: A magnetically-responsive surface structure comprises an array of hybrid microstructures on a substrate, where each hybrid microstructure comprises an elastomeric micropillar attached to the substrate and a rigid tile attached to the elastomeric micropillar. The rigid tiles collectively define a discontinuous, changeable surface. The hybrid microstructures further comprise a ferromagnetic material. The elastomeric micropillars are deflectable under a magnetic field so as to alter an orientation of the rigid tiles, thereby allowing a characteristic of the discontinuous, changeable surface to be manipulated.

Abstract: Apparatus and methods are provided to allow for creation an elastic laminate. Non-stretched elastic can be laid at peaks over a nonwoven layer contained in valleys and atop peaks. Stretched elastic can be laid over tented nonwoven to create nonwoven tunnels when a second nonwoven is laid atop the first nonwoven and elastic, and the tunnels resist un-stretching of stretched elastic strands by frictional or obstruction forces. A laminated material comprising a first and second layer of material bonded at spaced apart bond sites is disclosed, with a plurality of elastic strands disposed in a non-linear manner between said first and second layer of material, so that said strands meander in a cross-machine direction and traverse a machine direction line, restraining movement of the strands by frictional forces between the strands and the non-woven layers.

Abstract: The object of this invention is to provide a laminated automotive glazing having an obscuration area produced by printing the obscuration on a film laminated between at least two layers of plastic interlayers rather than printing and firing an enamel frit onto the glass. This results in a laminate having superior optical quality, higher strength and a lower probability of breakage as compared to a laminate with a black enamel frit obscuration.

Abstract: The invention relates to a security strip and security paper for obtaining security documents such as legal tender notes, checks or identification documents, comprising a cellulose support web that is completely embedded in a pulp substrate. As both the substrate and the support web are formed by plant fibers, a series of physical and chemical bonds are established between the fibers of both elements, the support web thus being perfectly integrated in the pulp. The cellulose support web will sometimes have a series of security elements, such as pigments, synthetic elements and/or security fibers of the type normally used in this type of application.
