Patent ID: 7067574

Claim:
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 methacrylic 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 said depolymerizable methacrylic resin particles (C) are particles of a homopolymer of a methacrylic monomer represented by the formula (IV): CH 2 ═C(CH 3 )COOR (IV) wherein R is an alkyl group or a hydroxyalkyl group having 1 to 5 carbon atoms, or a copolymer of at least two methacrylic monomers of the formula (IV), said high boiling point polyol (B) and said depolymerizable methacrylic 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.
