The present invention provides a coating composition capable of forming a coating film having a good appearance and design of a coating film and having coating film properties such as scratch resistance with a good balance. Furthermore, the present invention provides a method for forming a multilayer coating film including forming a coating film using the coating composition of the present invention.

Coating composition and method for forming multilayer coating film

Acid anhydride denatured chlorinated polyolefin (component A) which is composed of a copolymer of propylene and &#x3b1;-olefin wherein the chlorine contents is 15 to 24% by weight, denatured amount of acid anhydride is 0.6 to 2.0%, weight average molecular weight is 40000 to 120000, and acrylic denatured alkyd resin (component B) which is comprised of alkyd resin polymer part (b1) whose iodine value is 80 or more and oil length is 35 to 70, and acrylic resin polymer part (b2) whose glass-transition temperature is not less than 50&#xb0; C. wherein the weight average molecular weight is 10000 to 100000, weight ratio of the alkyd part and acrylic part is in a range of from 25/75 to 75/25, are used in a range of from 80/20 to 20/80 (A/B).

Primer composition for polyolefin materials

The present invention provides: an aqueous primer coating composition of which the deterioration of the water resistance is prevented with the high adhesion maintained, and which is excellent in the gasohol resistance and the pigment dispersion stability; and a thing coated with this aqueous primer coating composition. The aqueous primer coating composition according to the present invention, comprises acid anhydride-modified poly(olefin chloride) emulsion resin (A), aqueous alkyd resin (B) and aqueous novolac-type epoxy resin (C), wherein the contents of the (A), (B), and (C) are (A) 20 to 60 weight %, (B) 10 to 60 weight %, and (C) 10 to 60 weight % in terms of solid content weight % to the total resin solid content in the composition. The coated thing, according to the present invention, is coated with the present invention aqueous primer coating composition.

Aqueous primer coating composition and article coated therewith

The present invention provides a one-liquid low temperature hardenable type colored enamel paint and a one-liquid low temperature hardenable type clear paint, which are used for coating of plastic materials and sufficiently harden even by baking at a low temperature and can form a hardened coating film that is excellent in contaminationproofing and acidproofing without damaging flexibility. The colored enamel paint comprises: resin components, which include a polyesterpolyol and an acrylic polyol; a crosslinking agent, which includes a blocked isocyanate as the essential component and may further include a melamine resin; a blocked isocyanate dissociation catalyst, which at least includes a dibutyltin dicarboxylate; and a pigment. The clear paint comprises: a resin component, which includes an acrylic polyol; the crosslinking agent; and the blocked isocyanate dissociation catalyst.
