摘要:
The present invention provides a resin film which is excellent in various properties such as heat resistance, printability, mechanical strength, moisture absorption resistance, film-forming property and flexibility and can be suitably used in the printing applications. There is provided a printing film obtained by molding a thermoplastic resin composition (I) comprising 100 parts by mass in total of a mixed resin comprising 25 to 75% by mass of a rubber-modified styrene-based resin (A) and 25 to 75% by mass of a polyamide-based resin (B). The component (A) comprises a graft copolymer obtained by polymerizing a vinyl-based monomer in the presence of a rubber polymer, or a mixture comprising the graft copolymer and a (co)polymer of the vinyl-based monomer. The vinyl-based monomer comprises an aromatic vinyl compound and a cyanided vinyl compound, and further comprises a functional group-containing vinyl-based monomer in an amount of 0.1 to 1.2% by mass based on the component (A) in which an acetone-soluble component in the component (A) has an intrinsic viscosity of 0.15 to 1.5 dL/g (as measured at 30°C in methyl ethyl ketone). The composition (I) comprises the rubber polymer in an amount of 5 to 30 parts by mass based on 100 parts by mass of the composition.

This invention provides an infrared reflective layered product, particularly a back sheet for solar cells, which, even when it has a black colored or chromatically colored appearance, can reflect infrared radiation with certain wavelengths to prevent heat accumulation and, at the same time, has excellent heat resistance. The infrared reflective layered product comprises the following layer (B) as a base layer, the following layer (A) layered on one side of the layer (B), and the following layer (C) layered on the other side of the layer (B). Layer (A): a colored resin layer which has an absorptance of a light with a wavelength of 800-1400 nm of not more than 10%. Layer (B): a thermoplastic resin layer which shows a dimensional change (s) satisfying 1%≧s≧-1% when left at 150°C for 30 minutes. Layer C: a colored resin layer having a reflectance of a light with a wavelength of 400-1400 nm of not less than 50%.
Preferably, the layer (A) is formed of a resin containing an infrared transmittable coloring agent, and the layer (C) is formed of a resin containing a white pigment. A water vapor barrier layer (D) may be additionally provided.

The objective of the present invention is to provide a rubber-reinforced resin which, when formed into a molded article, can prevent contamination or soiling of an article contacted with the molded article or a device on the periphery of the molded article and is excellent in impact resistance and transparency, and an anti-static resin composition which is excellent in impact resistance and anti-static properties. The present rubber-reinforced resin comprises a rubber-reinforced copolymeric resin produced by polymerization of 20 to 95 parts by mass of monomer components comprising methyl methacrylate, an aromatic vinyl compound and a cyanidated vinyl compound in the presence of a rubbery polymer having a predetermined volume-average particle diameter, or comprises a mixture of the rubber-reinforced copolymeric resin and a copolymer of the above-mentioned monomer components. Additionally, the present anti-static resin composition comprises the above-mentioned rubber-reinforced resin and a polymer type anti-static agent, wherein the rubbery polymer is contained in an amount from 5% to 40% by mass. In each of the rubber-reinforced resin and the anti-static resin composition, the total amount of substances detected at a retention time of 10 to 24 minutes is 20,000 µg or less per gram of the sample as determined by pyrolysis GC analysis.

摘要:
A layered product is provided which is excellent in heat resistance, difficult to hydrolyze and excellent in weatherability, and has such flexibility that it can hardly crack even when folded, and further is prevented from curling, and thus is excellent in processability, productivity and handleability. The layered product comprises a base layer made of a thermoplastic resin (I) having a glass transition temperature of 120°C or higher, the base layer being layered on at least one side thereof with a layer made of an aromatic vinyl resin (II) having a lower glass transition temperature than the thermoplastic resin (I). The aromatic vinyl resin (II) is preferably a rubber-reinforced aromatic vinyl resin which contains a rubber-like polymer (a) selected from ethylene-α-olefin rubbers, hydrogenated conjugated diene rubbers, acrylic rubbers, silicone rubbers and silicone/acrylic composite rubbers in an amount of 5-40 parts by mass. The difference in glass transition temperature between the thermoplastic resin (I) and the aromatic vinyl resin (II) is preferably 10°C or more.
