The invention relates to a base comprising a closed cell foam core sheet having a closed cell foam layer with a density gradient between the center of the core and the surfaces of the core. The invention also relates to a method of making such a base by adding a first concentration of a first blowing agent to a first polymer to form a first mixture, adding a second concentration of a second blowing agent to a second polymer to form a second mixture, and extruding the mixtures to form the closed cell foam core sheet. The invention also relates to a method of making such a closed cell foam core sheet base comprising the steps of adding a blowing agent to a polymer to form a mixture, melting the mixture, extruding the mixture from a die, and rapidly quenching the mixture against a high heat transfer surface.

Disclosed is a flame-retardant member that is flexible and highly flame retardant. Specifically disclosed is a flame-retardant polymer member which has a polymer layer (B) and a flame-retardant layer (A) on at least one surface of the polymer layer (B), wherein the flame-retardant layer (A) contains a stratified inorganic compound (f) in a polymer (X).

The purpose of the present invention is to provide a polarizing plate that does not easily curl due to environmental changes, and an image display and liquid crystal display device provided with the polarizing plate. This polarizing plate is provided with, a polarizing element, a protective film and a release film, in that order. The modulus of elasticity of the release film is at least 2.0 GPa. The thickness P (micrometer) of the polarizing element, the thickness Q (micrometer) of the protective film, and the thickness T (micrometer) of the release film satisfy formula (A). Formula(A): T>=(2.8*P-1.2*Q)+50

The base comprises a foam core layer, which comprises a polymer that has been expanded through the use of a blowing agent, and at least one polymeric surface smoothing layer, which comprises a solution polymer.

The present invention relates to an image receiver element comprising a single low density layer, wherein the single low density layer comprises non-crosslinked aliphatic polyester containing non-interconnected void space, and wherein the single low density layer does not absorb more than 3 weight % moisture at 80% RH and 21.3° C. as compared to the weight % moisture of said single low density layer at 20% RH and 21.3° C. The invention relates to a method of forming such an image receiver element, a printing system comprising an imaging material and the image receiver element, and a method of printing comprising obtaining an imaging material comprising a colorant layer; obtaining the image receiver element; superposing the colorant layer with the receiver element; and transferring colorant from the imaging material to the image receiver element.

In one embodiment, the present invention is an adhesive film having (alpha) a layer of polyvinyl chloride resin film and (beta) an adhesive layer in the stated order from the surface-layer side, wherein the (beta) adhesive layer is formed from an adhesive including: (A) 100 parts by mass of an acrylic polymer that satisfies the features (a1) and (a2), specifically (a1) an acid value of 18-27 mg KOH / g, and (a2) a mass-average molecular weight of 500,000 to 1,000,000; and (B) 0.1-3 parts by mass of a compound having two or more isocyanate groups per molecule. In another embodiment, the present invention is an adhesive film having (alpha) a layer of polyvinyl chloride resin film and (beta) an adhesive layer in the stated order from the surface-layer side, wherein the (beta) adhesive layer hasa tackiness of 12-25 N at a surface temperature of 5 DEG C and has a tackiness of 12-23 N at a surface temperature of 35 DEG C.

The invention discloses a bag for automatic cheese canning, which comprises a bag body with an insert edge structure; the bag body comprises a front surface, a back surface and insert edges on the left side and the right side; a certain width of bottom sealing line penetrating through the front surface, the back surface and the two insert edges is formed at the bottom of the bag body; a lower oblique angle is formed at the lower part of the bag body; the bag body consists of layered co-extrusion blown thin films with symmetrical structures of which the number of layers is seven-eleven; and each layered co-extrusion blown thin film is provided with an inner heat-sealed moisture barrier layer, an inner bonding layer, an inner oxygen barrier layer, an incense keeping core layer, an outer oxygen barrier layer, an outer bonding layer and an outer heat-sealed moisture barrier layer from inside to outside in sequence. The bag has the beneficial effects that a three-dimensional structure of the bag body is stable, the inner layer friction performance and the outer layer friction performance of the bag body are properly set, used materials are saved, and the strength is high. The bag is particularly suitable for automatic cheese canning.

　The present invention provides a polystyrene mold-release film having sufficiently excellent heat dimension stability and curl resistance. The present invention pertains to a mold-release film composed of a biaxially oriented polystyrene film containing a syndiotactic polystyrene resin, the mold-release film being characterized in that at least one surface is matt-finished and the curl rate of the mold-release film is 80% or less.

The invention discloses umbrella water-based ink for pongee fabrics and a coating method of the water-based ink. The water-based ink comprises, in parts by weight, 35-45 parts of waterborne polyurethane resin, 10-20 parts of water-based acrylic resin, 20-30 parts of alcohols, 20-30 parts of titanium dioxide and / or 15-20 parts of color paste and 5-12 parts of an assistant.
