A coating composition is described that can be completely biodegradable and well suited for use in laminating films to substrates. The coating composition contains a biodegradable polymer, such as a polyvinyl alcohol polymer. The coating composition can be applied to a biodegradable film and then adhered to a substrate, such as a paper substrate.

The present invention relates to a multilayer tubular structure (MLT) intended for the transport of fluids, in particular of petrol, especially alcohol-containing petrol, comprising, from the outside inwards, at least one barrier layer (1) and at least one inner layer (2) located below the barrier layer, said inner layer (2), or all the layers (2) and the other optional layers located below the barrier layer, containing on average from 0 to 1.5% by weight of plasticizer relative to the total weight of the composition of the layer (2) or to the total weight of all the compositions of the layers (2) and the other optional layers located below the barrier layer, respectively, said inner layer (2) predominantly comprising at least one polyamide of aliphatic type or consisting of more than 75% of aliphatic units, said aliphatic polyamide being chosen from: a polyamide denoted A, having a mean number of carbon atoms per nitrogen atom, denoted C.sub.A, of from 4 to 8.5, advantageously from 4 to 7; a polyamide denoted B, having a mean number of carbon atoms per nitrogen atom, denoted C.sub.B, of from 7 to 10, advantageously from 7.5 to 9.5; a polyamide denoted C, having a mean number of carbon atoms per nitrogen atom, denoted C.sub.C, of from 9 to 18, advantageously from 10 to 18; with the proviso that when said inner layer (2) comprises at least three polyamides, at least one of said polyamides A, B and C is excluded.

A floor panel for forming a floor covering comprises a substrate consisting of at least two substrate layers differing in density and, on at least one pair of opposite edges, is provided with coupling parts of the so-called push-lock type. Vertically active locking surfaces, where they cooperate in the coupled condition of two of such floor panels, define a tangent line which is horizontal or does not deviate more than 50 degrees from the horizontal. The locking surfaces are situated closer to the upper side of the first substrate layer than to the lower side of the first substrate layer.

An object is to provide a metal-resin bonded member that is easy to manufacture and has high bonding strength. The metal-resin bonded member includes a metal body having an iron oxide layer on the surface and a resin body bonded to the metal body via the iron oxide layer. The iron oxide layer has a thickness of 50 nm to 10 μm. The iron oxide layer comprises 60-40 at % Fe and 40-60 at % O at the outermost surface side. The iron oxide layer contains magnetite (Fe.sub.3O.sub.4). The iron oxide layer is formed by heating the surface of an iron-based substrate at 200-850° C. in an oxidation atmosphere. The resin body is composed of polyphenylene sulfide (PPS). The bonding of the metal body and the resin body via the iron oxide layer can be carried out by insert molding, thermal adhesion utilizing friction heating, etc.

A laminated foam sheet having a polyethylene resin foam layer and an antistatic polyethylene layer laminated on one or both sides thereof is produced by coextruding melts for respective layers, wherein the melt for the antistatic layer contains a polyethylene resin, an ionomer resin antistatic agent and a specific amount of volatile plasticizer blend containing an alcohol and a saturated hydrocarbon or a dialkyl ether. The antistatic layer of the obtained laminated foam sheet has specific morphology.

The present invention is a windshield on which an information acquisition device that acquires information from outside of a vehicle by emitting and/or receiving light can be arranged, the windshield including: an outer glass plate; an inner glass plate; an interlayer film arranged between the outer glass plate and the inner glass plate; and a mask layer laminated on at least one of a surface on a vehicle interior side of the outer glass plate and a surface on a vehicle exterior side of the inner glass plate, in which the interlayer film includes a colored shade region, a transparent non-shade region, and a transparent sheet member that is fitted into at least one through hole formed over the shade region and the non-shade region.

The invention relates to a multilayer plastic film, in particular a multilayer plastic composite film, preferably a multilayer plastic packaging film, based on plastic recyclate (recycled plastic), in particular based on plastic recyclate originating from waste, with a plastic recyclate content of at least 80% by weight, based on the plastic film, and to its use, in particular as packaging material. The plastic recyclate is preferably post-consumer plastic recyclate (PCR plastic recyclate), in particular PCR recycled films.
