Provided is a cooking utensil having an excellent design. The cooking utensil includes a bottom and a side extending substantially upward from a perimeter of the bottom. The bottom includes a bottom laminate film on an inner surface thereof. The side includes a side laminate film that is different from the bottom laminate film on an inner surface thereof. The bottom laminate film and the side laminate film have different color tones.

Cooking utensil

The present invention provides a coating composition that gives a coating film with better abrasion resistance. The present invention relates to a coating composition including: a fluororesin; and inorganic particles, the inorganic particles having a new Mohs hardness of 10 or higher and having a substantially spherical shape.

Coating composition, coating film, and laminated body

The invention provides a composition that can provide a film exhibiting excellent adhesion to a substrate and having excellent non-stickiness. The composition contains a fluororesin, a heat-resistant resin, water, and a solvent having a boiling point of 205&#xb0; C. or higher.

Composition and coating film

A coating composition that provides a coating film having better abrasion resistance. The composition includes: a fluororesin; and inorganic particles, the inorganic particles having a new Mohs hardness of 10 or higher and a substantially spherical shape. Also disclosed is a coating film produced from the coating composition and a laminate such as a cooking utensil including a substrate and the coating film.

The present invention provides a laminate excellent in abrasion resistance, high in hardness, and excellent in adhesion between a substrate and a primer layer and adhesion between an intermediate layer and a top coat layer. The laminate includes: a substrate; a primer layer disposed on the substrate, the primer layer containing inorganic particles (a1) having an average particle size of 3 &#x3bc;m or greater and a heat-resistant resin (a2), but not containing a fluororesin; an intermediate layer disposed on the primer layer and containing a fluororesin (b1) and a heat-resistant resin (b2); and a top coat layer disposed on the intermediate layer and containing a fluororesin (c1).

Laminate

The present invention aims to provide an aqueous dispersion that contains particles of a fluoropolymer at high concentrations and has a less variable pH, and in which aggregates are less likely to be generated even after the aqueous dispersion has been stored for a long time. The present invention relates to an aqueous dispersion, including: particles of a fluoropolymer having an average primary particle size of 0.1 to 0.5 &#x3bc;m in an amount of 50 to 70% by mass; a nonionic surfactant in an amount of 2 to 10% by mass based on the amount of the fluoropolymer; and ammonium lauryl sulfate in an amount of 0.0001 to 1% by mass based on the amount of the fluoropolymer, wherein an amount of a fluorine-containing anionic surfactant is less than 10 ppm.

Aqueous fluoropolymer dispersion

A coating composition which is an aqueous dispersion of a fluororesin particle (A) including a fluororesin, a resin particle (B) the decomposition and vaporization of which begin at a temperature not higher than a decomposition temperature of the fluororesin, and a nonionic surfactant (C) in an aqueous medium. The aqueous dispersion contains the resin particle (B) in an amount of 5 to 25 parts by mass based on 100 parts by mass of the fluororesin particle (A) and a fluorine-containing surfactant in an amount smaller than 500 ppm relative to the fluororesin particle (A).

Coating composition

This invention provides the invention provides a fluororesin aqueous dispersion composition comprising a tetrafluoroethylene-based polymer and an aliphatic polyoxyalkylene ether dispersant incorporated therein, wherein the aliphatic polyoxyalkylene ether dispersant shows a 50% decomposition temperature of not lower than 250&#xb0; C.

Fluorinated resin water dispersion composition and fluorinated water base coating composition

The present invention provides a resin aqueous dispersion composition comprising water and at least one kind of resin particle, wherein when a primary average particle of each resin particle is taken as a sphere of the same volume, a nonionic surfactant is present in the composition in an amount which occupies 75 to 95% of a theoretical void among resin particles of 26% when each resin particle is arranged in a close packed structure. The nonionic surfactant is a solvent which is substantially nonvolatile in a temperature range of up to 100&#xb0; C. and evaporates or thermally decomposes at a temperature lower than the thermal decomposition temperature of the resin particles. The resin aqueous dispersion composition can be coated thickly and can prevent development of mud crack.

Resin aqueous dispersion composition

The present invention relates to an aqueous dispersion composition of fluororesin for coating comprising (A) fluororesin particles, (B) a nitrogen-free high boiling point polyol having a boiling point of at least 100&#xb0; C. and containing at least 2 hydroxyl groups, (C) depolymerizable acrylic resin particles having a decomposition and vaporization temperature within a temperature range of up to the decomposition temperature of said fluororesin particles, (D) a nonionic surfactant, and (E) an aqueous medium, wherein the high boiling point polyol (B) and the depolymerizable acrylic resin particles (C) are respectively contained in an amount of 5 to 18 parts by mass and 5 to 25 parts by mass based on 100 parts by mass of fluororesin particles (A) and an oxidant and an amine-type solvent are not contained.
