A flame-retardant, characterized in that it comprises a layered titanic acid in the form of a nano sheet which is formed by a method comprising treating a layered titanic acid salt with an acid or warm water and then reacting the resultant mixture with an organic basic compound, or carrying out the step of treating a layered titanic acid salt with an acid or warm water and the step of reacting with an organic basic compound, in one pot, to thereby swell or separate the layers; and a flame-retardant resin composition, characterized in that it comprises 100 parts by weight of a resin and 0.5 to 50 parts by weight of the above layered titanic acid in the form of a nano sheet.

Provided are: a laminate including a first substrate, a second substrate, a print layer provided on the second-substrate-side surface of the first substrate, and an adhesive layer which is disposed between the print layer and the second substrate and which bonds the first substrate and the second substrate to each other, the print layer being formed from a printing ink composition (A) that includes an urethane resin (A1) and a vinyl chloride-vinyl acetate copolymer resin (A2), and the adhesive layer being formed by applying a two-liquid-type polyurethane-based adhesive (B) that contains a polyol (B1) having a number-average molecular weight of 2,300 or less and an isocyanate compound (B2); and a method for manufacturing the laminate.

A synthetic resin container that has attained an enhancement of steam barrier capability while retaining a high gas barrier capability against oxygen, etc. through simple and easy means. There is provided a PET bottle obtained by forming, on an internal surface of wall portion (1) of PET resin constructing the main body of the container, barrier coating (2) containing a silicon oxide wherein among silicon, oxygen and carbon composition ratios (atom%), the oxygen composition ratio is 50 atom% or higher while the carbon composition ratio is in the range of 3 to 20 atom% in accordance with plasma CVD technique using an organic silicon compound gas and oxygen gas as raw materials. Preferably, the carbon composition ratio of the barrier coating (2) is 8 atom% or below.

A flexible hose of the invention has a hose wall which is formed by laminating resin layers. The resin layer acting as a gas barrier is formed by spirally winding a gas barrier resin strip and thermally fusing or bonding axially adjoining edges of the strip to each other. The resin layers are thermally fused or bonded to one another to become one piece.

A method for forming a vapor deposition film is composed of a silicon oxide on a surface of a substrate is disclosed in which the substrate to be processed is held in a plasma processing chamber and a chemical plasma processing is conducted by supplying an organic silicon compound and an oxidizing gas into the processing chamber. By changing the supply rate of the oxidizing gas during formation of a deposition film while keeping the supply rate of the organic silicon compound gas at a certain fixed rate, there can be formed a chemical vapor deposition film which is excellent in adhesion, plasticity, flexibility, oxygen barrier property and moisture barrier property.

The invention relates to a biodegradable polyester nanocomposite material, and particularly relates to a biodegradable polyester nanocomposite material containing functionalized starch nanocrystal and preparation method of the biodegradable polyester nanocomposite material. The biodegradable polyester nanocomposite material containing functionalized starch nanocrystal is prepared by blending compound master batch of functionalized starch nanocrystal and a polymer with biodegradable polyester granules; the functionalized starch nanocrystal in the biodegradable polyester nanocomposite material is 20-60% of dry weight of the polymer, and is 1%-15% of the total dry weight of the biodegradable polyester and the polymer. The functionalization of the biodegradable polyester nanocomposite material is realized, the prepared biodegradable polyester nanocomposite material containing functionalized starch nanocrystal is an environment-friendly material and has gas barrier property, controllable degradability, as well as a function that fluorine, silicon-containing low surface energy grafted chain is capable of migrating to matrix surface.

A synthetic resin container excellent in heat resistance and high in gas barrier property, and a production method thereof. The container is produced by having a gas barrier material blended into a base phase and subjecting the blended substance to at least two biaxial stretching blow molding processes with heat treating processes in between.
