Abstract: Provided are: [1] a foaming method including: a step (X) of mixing a foamable composition containing a foaming agent (A) having a time required for a reduction in dynamic surface tension thereof to start of 60,000 ms or less, which is measured by a maximum bubble pressure method, and an organic solvent (B), and a gas, and foaming the composition; and a step (Y) of reducing the size of foam with a porous body; and [2] an article including: a foam discharge container; and a foamable composition in the foam discharge container, wherein the foamable composition contains a foaming agent (A) having a time required for a reduction in dynamic surface tension thereof to start of 60,000 ms or less, which is measured by a maximum bubble pressure method, and an organic solvent (B), and wherein the foam discharge mechanism of the foam discharge container includes a porous body.

Abstract: There are provided a resin solution substantially applicable to thermal imprinting, a thin film thereof, and manufacturing methods of those. A thermal imprinting resin solution for forming a thin film used for thermal imprinting applications comprises a thermoplastic resin and greater than or equal to at least one kind of solvent which can dissolve the resin, and an containing amount of foreign particles having a grain diameter larger than or equal to 0.2 ?m is controlled to be less than 3000 particles/cm3. Moreover, remaining volatile compositions in a thin film are set to be less than or equal to 0.25% when the thin film is formed from the thermal imprinting resin solution.

Abstract: To provide a powder coating composition which comprises 100 parts by weight of fluorine-containing resin and 1 to 40 parts by weight of tetrafunctional or trifunctional silicate compound or a condensation product thereof, has a function of removing electrostatic charge and gives a coating film having a high hardness and stain-proof property.

Abstract: To provide the thermosetting powder coating composition which comprises a fluorine-containing copolymer having crosslinkable functional group and a curing agent, in which the fluorine-containing copolymer has a fluoroolefin unit, has a fluorine content of not less than 10% by weight and is not dissolved in tetrahydrofuran substantially. A coating line can be shared with other powder coating composition because even when the composition mixes to other powder coating composition, it causes no coating defects, and yet a coated article having a coating film excellent in physical properties can be provided.

Abstract: To provide a thermosetting powder coating composition which comprises a powder of a composite resin comprising a vinylidene fluoride polymer having crosslinkable functional group and a methyl methacrylate polymer and having a melt flow rate of 1 to 1,000 g/10 min when measured at 130° C. at a load of 2.1 kg. The coating composition has advantages that the preparation thereof is easy because pulverization can be carried out at room temperature as well as at low temperatures, the composite resin has excellent compatibility with various curing agents and the composition gives a coating film having excellent properties.
