The composite structural material of the present invention includes a base (X) and a layer (Y) stacked on the base (X). The layer (Y) includes a reaction product (R) of a metal oxide (A) and a phosphorus compound (B). In the infrared absorption spectrum of the layer (Y) in the range of 800 to 1400 cm.sup.1, the wave number (n.sup.1) at which the infrared absorption reaches maximum is in the range of 1080 to 1130 cm.sup.1.

A barrier film including a substrate, a base (co)polymer layer applied on a major surface of the substrate, an oxide layer applied on the base (co)polymer layer, and a protective (co)polymer layer applied on the oxide layer. The protective (co)polymer layer is formed as the reaction product of a first (meth)acryloyl compound and a (meth)acryl-silane compound derived from a Michael reaction between a second (meth)acryloyl compound and an aminosilane. The first and second (meth)acryloyl compounds may be the same. In some embodiments, a multiplicity of alternating layers of the oxide layer and the protective (co)polymer layer may be used. An oxide layer can be applied over the top protective (co)polymer layer. The barrier films provide, in some embodiments, enhanced resistance to moisture and improved peel strength adhesion of the protective (co)polymer layer(s) to the underlying layers. A process of making, and methods of using the barrier film are also described.

A purpose of the present invention is to provide a photosensitive resin composition which retains satisfactory image resolution and gives cured objects reduced in wet-heat dissolution or contamination and having satisfactory wet-heat adhesiveness. The photosensitive resin composition of the present invention comprises: (A) a cationic photopolymerization initiator which comprises a salt of a cation with an anion represented by formula (1) (wherein R.sub.1 to R.sub.4 each independently represent a C1.sub.-18 alkyl or C.sub.6-14 aryl group, provided that at least one of R.sub.1 to R.sub.4 represents a C.sub.6-14 aryl group); and (B) an epoxy compound. R.sub.1 to R.sub.4 may be each independently either a phenyl group having one or more perfluoroalkyl groups as substituents or a phenyl group having one or more fluorine atoms as substituents. R.sub.1 to R.sub.4 may be each independently a pentafluorophenyl or bis(trifluoromethyl)phenyl group.

An insulated panel assembly having improved insulative R-value. The insulated panel assembly comprises a cover panel, a first insulation layer, and at least one additional insulation layer, wherein the at least one additional insulation layer has a higher R-value than the first insulation layer. The first insulation layer is secured to the cover panel. The first insulation layer further forms at least one recessed portion. The at least one additional insulation layer is positioned in the at least one recessed portion of the first insulation layer. Examples of the at least one additional insulation layer may include vacuum insulated panels and modified atmosphere insulation panels.

The invention relates to a sealed holographic medium comprising a layer construction containing a photopolymer layer and a sealing layer, to a process for producing the sealed holographic medium, to a kit of parts, to a layer construction for sealing and to the use thereof.

The present disclosure provides adhesive articles that can be removed from surfaces without damage by having reduced or eliminated contribution of a core backing to peel force generated by the adhesive during removal. In some instances, this can be accomplished by a core that loses structural integrity in a direction normal to a plane defined by a major surface. In other instances, the contribution is reduced by compromising the interface between the core and a peelable adhesive layer.

The present invention relates to a laminated cellulose-based liquid or semi-liquid food packaging material, comprising a brown or dark bulk layer from non-bleached, cellulose-based material, an outside substrate layer having a white print surface to hide the dark colour of the bulk layer, and on the inside an oxygen barrier layer and an innermost heat sealable layer. The invention further relates to the method for manufacturing the laminated packaging material and to a packaging container for liquid food packaging, comprising the laminated packaging material.

A polyester pressure-sensitive adhesive composition is provided including a polyester resin having a predetermined amount of a structural unit derived from a hydrogenated polybutadiene structure-containing compound, or a polyester resin having a structural unit derived from a hydrogenated polybutadiene structure-containing compound and a predetermined amount of a structural unit derived from an aromatic ring structure-containing compound. The polyester pressure-sensitive adhesive composition has superior adhesion to a polyolefin base material and is highly transparency.
