Abstract

PURPOSE:To form a decorative coating film excellent in adhesion with a topcoating film by coating part of the surface of a specific cured topcoating film with a decorative coating compsn. obtd. by adding a phosphoric ester to a specific two-coating compsn. CONSTITUTION:Part of the surface of a cured topcoating film having a static glass transition point of 60-130 deg.C t is coated with a decorative coating compsn. mainly comprising a hydroxylated resin (e.g. a polyester polyol or an acrylic polyol), a polyisocyanate compd. (e.g tolylene diisocyanate or diphenylmethane diisocyanate), and a phosphoric ester (e.g. monoethyl phosphate) in such a manner that a decorative coating film is formed in a shape of lines, characters, or patterns. Since the resin reacts easily with the isocyanate compd. to crosslink at a room temp., they are stored separately and mixed just before they are used. The ester is pref. premixed into the ester and/or the isocyanate compd. The addition of the ester improves the adhesion between the topcoating film and the decorative coating film.

2. Description of the Related Art A coating material for cosmetics is partially applied in a shape such as a line, a pattern or a character on the outer panel portion of an automobile, especially a door locker portion, which has been overcoated to improve its design and beauty. There are many things that can be improved. As this cosmetic coating, a room-temperature-drying coating containing a drying oil-modified alkyd resin as a main component has been used so far, but it has a defect of poor abrasion resistance and weather resistance. As a solution to these drawbacks, a two-pack type coating containing a hydroxyl group-containing resin and a polyisocyanate compound as main components is used.

On the other hand, on the other hand, top coats having excellent acid resistance due to global environmental pollution and improved scratch resistance have been developed, and the surface of these top coats is more common than conventional ones. In addition, it has been pointed out that the above two-component cosmetic coating composition has insufficient adhesion to the top coating film due to its high static glass transition temperature, and its solution is desired. Generally, the static glass transition temperature of a top-coat cured coating having improved acid resistance and scratch resistance is 6
It is contained in the range of 0 to 130 ° C., and the static glass transition temperature of a usual coating film is lower than that.
