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&#xb0; 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.

Printing film and face material

The infrared reflective layered product can reflect infrared radiation with certain wavelengths to prevent heat accumulation while exhibiting excellent heat resistance. The product includes a base layer (B), a layer (A) layered on one side of the layer (B), and a layer (C) layered on the other side of the layer (B). Layer (A) is 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) is a thermoplastic resin layer which shows a dimensional change (s) satisfying 1%&#x2267;s&#x2267;&#x2212;1% when left at 150&#xb0; C. for 30 min. Layer C is a colored resin layer having a reflectance of a light with a wavelength of 400-1400 nm of not less than 50%. The product may also include a water vapor barrier layer (D).

Infrared reflective laminate

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 &#x3bc;g or less per gram of the sample as determined by pyrolysis GC analysis.

Rubber-reinforced resin, anti-static resin composition, molded article and laminate

A molding material and a molded article for laser welding are provided, which comprise a thermoplastic resin (A) comprising a rubber-reinforced resin (A1) obtained by polymerizing a vinyl monomer in a presence of a rubber-like polymer (a), or a composition (A2) of the rubber-reinforced resin (A1) and a (co)polymer (b) of a vinyl monomer, and which have a light transmittance at a wavelength of 808 nm in a range of 5% or higher when molded into a 4 mm-thick sample piece. The rubber-like polymer (a) dispersed in the thermoplastic resin (A) preferably has a weight average particle size of 50 to 220 nm, and preferably comprises particles of 300 nm or larger in diameter in an amount of 0 to 20 wt % relative to 100 wt % of the component (a). A laser light can transmit the molding material and the molded article, and allow the molding material and the molded article to be laser-welded with various resin moldings.
