摘要： 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°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. This composition is an aqueous dispersion composition of fluororesin for coating, which has favorable storage stability, can be coated thickly, controls development of mud crack and can form a coating film in which cracking and coloring do not occur when baking. Also, the composition controls discharge of endocrine disrupter substances as much as possible.
