aqueous dispersions based on poly (vinyl acetate), fusible by heat

摘要

It has been discovered that pastes of particulate, thermoplastic, poly(vinyl acetate) type polymers dispersed in a soft resinous phase can be prepared which heat-set by fusion of the thermoplastic binder. When pigmented or otherwise colored, these formulations have utility as printing inks. When uncolored, they can be used as clear overprint coatings. In addition, these fusible pastes have utility as specialty coatings in adhesives and can be fabricated into self-supporting shapes.
