Document Type and Number:
WIPO Patent Application WO/2012/147418
Kind Code:
A1
Abstract:
The problem to be solved by the invention is to provide an aqueous composite resin composition with which it is possible to form a coating film having excellent long-term shelf life and excellent water resistance and solvent resistance. The invention relates to an aqueous composite resin composition comprising composite resin particles (A), wherein a portion or all of epoxy resin (a2) is encapsulated in particles of polyester resin (a1) having sulfonic acid groups, and (B) an aqueous medium, the aqueous composite resin composition being characterized in that the mass ratio [(a1)/(a2)] of polyester resin (a1) and epoxy resin (a2) forming the composite resin particles (A) is within a range of 95/5 to 30/70.
