ABSTRACT:
A water-based paint confers wet primed adhesion if its binder is a latex whose polymer is a vinyl chloride/acrylic or an all-acrylic containing polymerized therein (based on weight of main monomers) not only 0.3-5% of (meth) acrylic acid but also a fraction of hydroxymethyl diacetone acrylamide (HMDAA) which must be at least 1 % in case of vinyl chloride/acrylics and at least 2% in case of all-acrylics. But, surprisingly, when such a latex is diluted by blending with a vinyl acetate/acrylic latex which by itself does not confer wet primed adhesion, superior wet primed adhesion is obtainable even when the overall level of HMDAA is only 0.65% when the HMDAA latex is an all-acrylic and only 0.40% when the HMDAA latex is a vinyl chloride/acrylic.
