The present invention relates to an aqueous dispersionncomposition of fluororesin for coating comprising (A) fluororesinnparticles, (B) a nitrogen-free high boiling point polyol having a boilingnpoint of at least 100°C and containing at least 2 hydroxyl groups, (C)ndepolymerizable acrylic resin particles having a decomposition andnvaporization temperature within a temperature range of up to thendecomposition temperature of said fluororesin particles, (D) annonionic surfactant, and (E) an aqueous medium, wherein the highnboiling point polyol (B) and the depolymerizable acrylic resin particlesn(C) are respectively contained in an amount of 5 to 18 parts by massnand 5 to 25 parts by mass based on 100 parts by mass of fluororesinnparticles (A) and an oxidant and an amine-type solvent are notncontained. This composition is an aqueous dispersion compositionnof fluororesin for coating, which has favorable storage stability, cannbe coated thickly, controls development of mud crack and can form ancoating film in which cracking and coloring do not occur when baking.nAlso, the composition controls discharge of endocrine disrupternsubstances as much as possible. |
