    摘要: A method of painting a substrate having an undercoat or intermediate coat, which comprises applying to the coated substrate
    (1) a water-borne clear paint comprising a mixture consisting of, per 100 parts (by weight) thereof,
    (A) 30 to 94 parts of a vinyl copolymer having an acid value of 5 to 100, a hydroxyl value of 20 to 100, a solubility parameter (δsp) of 9.0 to 13.0 and a number average molecular weight of 3,000 to 50,000, and which is prepared by copolymerising an ethylenic monomer having an acid group, an ethylenic monomer having a hydroxyl group and another, copolymerisable ethylenic monomer; (B) 5 to 40 parts of a cross-linking component; and (C) 1 to 30 parts of resin particles swollen with an organic solvent having a solubility parameter of 7.5 to 13.0, the swollen resin particles having an average particle size of 0.01 to 10 µm; and (2) (without curing the water-borne clear paint) a thermosetting clear paint comprising a mixture consisting of, per 100 parts (by weight) thereof,
    (D) 60 to 95 parts of a copolymer having a hydroxyl value of 20 to 100 and a solubility parameter not less than 0.3 different from that of the vinyl copolymer, and which is prepared by copolymerising an ethylenic monomer having a hydroxyl group and another, copolymerisable ethylenic monomer; and (E) 5 to 40 parts by weight of a cross-linking component.

    摘要: New and improved curable compositions useful as non-yellowing, acid resistant coatings for a variety of sub­strates and as adhesives and binders are disclosed. The curable compositions comprise a polymeric component com­prising poly(C₁-C₆ alkyl acrylamidoglycolate) functional units and poly (active hydrogen) functional units and pre­ferably an effective amount of a protic acid crosslinking catalyst. In preferred embodiments acid-catalyzed room tem­perature curable coating compositions are provided. The compositions may be cured effectively at lower temperatures without the use of amines or other toxic crosslinking agents and do not liberate formaldehyde on curing. A method for making poly(C₁-C₆ alkyl acrylamidoglycolate) functional polymers is also disclosed.
