This invention provides a cationic electrodeposition coating composition which exhibits high paint stability, forms coating film excelling in conductivity, intimate adhesion, corrosion resistance, finished appearance and acid resistance, and is capable of forming uniform electrocoated film also on substrates having uneven surfaces, characterized by comprising a conductive filler dispersion paste, base resin and a curing agent, said paste being formed by dispersing a conductive filler (A) composed of high conductive carbon black (a) and at least one conductive powder (a) selected from furnace black, graphite and conductive whisker, using a pigment-dispersing resin (B), the composition (i) containing 30-100 wt parts of a conductive filler (A) which contains at least 2 wt parts of high conductive carbon black (a), per 100 wt parts of combined solid content of the base resin and the curing agent, (ii) the weight ratio of the conductive powder (a)/high conductive carbon black (a) being within a range of 0.4-20, and (iii) the pigment-dispersing resin (B) being acrylic resin-derived pigment-dispersing resin formed by copolymerization of (meth)acrylic monomer (b) which is modified with mono- or poly-alkylene glycol or a monoether derivative thereof; nitrogen-containing, radical-polymerizable unsaturated monomer (b) and other radical-polymerizable unsaturated monomer (b).

Cationic electrodeposition coating compositions

A multi-layer application film formed by laminating at least two resin films, a top layer film (I) being formed from a crosslinkable resin coating composition (A), an under layer film (II) being formed from a thermoplastic resin (B), showing practically no stickiness per se, and having a tensile elongation at breakage in the range of 50 to 1000%, said multi-layer application film being applied onto a plastic substrate.

Coated film and method of laminating the same

A decorative film for use in plastics molding, said decorative film being a laminate film prepared by outwardly and successively laminating a polyolefin film layer, a primer layer, optionally a topcoating layer and a releasable layer, said primer layer being a coating film formed from an isocyanate-curing type resin composition containing (A) a hydroxyl group-containing resin having a hydroxyl number of 30 to 200 KOH mg/g on an average and a weight average molecular weight of 1000 to 80000, (B) a polyolefin based resin and (C) a (blocked)polyisocyanate compound in such mixing amounts that a number of the isocyanate group in the component (C) is in the range of 0.1 to 0.9 per one hydroxyl group in the component (A) and that the component (B) is in the range of 1 to 90% by weight based on a total weight of the components (A), (B) and (C), and having a static glass transition temperature of 20 to 70&deg; C., an elongation of 10% or more and a tensile strength of 0.5 kgf/mm or more; a process for preparing the decorative film and an injection-molded part by use of the decorative film.
