    摘要： [Problem] In a coating method of a two-coat one-bake system where a clear coat paint is coated after a base coat paint is coated, then these two coated layers are simultaneously hardened, adhesive strength between the two coated layers is to increase in comparison with the conventional method. [Solution] Provided is a coating method; A specific hardener is used in the clear coat paint. The hardener is one containing a polyisocyanate derived from 1,6-hexamethylene diisocyanate, satisfying all the following conditions: 1) Hardener does not virtually include diisocyanate monomer, 2) Viscosity of hardener is not more than 1000 mPa·s/23° C., 3) Content of HDI trimer in hardener is not less than 60 weight %, and 4) Content of HDI dimer in hardener is less than 10 weight %.

    摘要： The present invention is directed to a liquid, storage-stable isocyanate prepolymer having an isocyanate group content of from 10 to 30% by weight, prepared by reacting:
    i) a polyamine containing at least two aromatically bound primary amino groups prepared by hydrolyzing an isocyanate compound having an isocyanate group content of from 0.5 to 40% by weight, with ii) an isocyanate mixture comprising
    a) from 50 to 100% by weight of diphenyl­methane diisocyanates of which from 3 to 50% by weight consist of the 2,2′- and 2,4′-isomers, and b) the balance being polyphenylpolymethylene polyisocyanates, with the proviso that if said mixture comprises from 95 to 100% by weight of diphenylmethane diisocyanate, at least 15% by weight of said diisocyanate consisting of the 2,2′- and 2,4′- isomers.
