Abstract:
A dried film reinforced with coalescable water insoluble polymer particles which are substantially noncoalesced is disclosed. Also disclosed are dried films reinforced with noncoalesced water insoluble polymer particles which are readily water dispersible. Also disclosed are stable aqueous dispersions for formation of such films which comprise (a) a water insoluble component comprising coalescable polymer particles which have a Tg less than 55 °C and a majority of which have a particle size of less than 1 micron; and (b) a water soluble component which comprises a water soluble polymer capable of inhibiting coalescence of the polymer particles, or a water soluble polymer and a component capable of inhibiting coalescence of the polymer particles.

Abstract:
A paint sealer composition consisting of low VOC solvent borne coatings. Especially preferred are compositions comprising about 5-70% copolymer and about 10-50% solvent and a crosslinking agent, said copolymer comprised of ethylenically unsaturated monomers containing hydroxyl groups and other vinyl monomers.
Abstract:
Compositions useful as printing inks or as dry or wet concentrates for the preparation of inks, comprising substantially homogenous blends of from about 0.1 to about 50.0 wt. % water dispersible polyurethane, and conversely from about 99.9 to about 50.0 wt. % water dispersible polyester, and preferably containing from about 1.0 to about 95.0 wt. % of a solvent system comprising water or water admixed with cosolvent, the cosolvent comprising up to about 30.0 wt. % of the solvent system. These blends show exceptionally marked improvements in certain physical properties such as: stability of viscosity to ambient and process conditions; linearity of viscosity change with water dilution; consistency of viscosity for a great variety of pigments; and greatly improved shelf-life (no significant polymer segregation or layering). Such properties greatly enhance the utility of these blends for use in pigmented or dyed printing inks and in other substrate coating formulations which may or may not contain colorants. Also disclosed is a process useful for the preparation of such compositions.
Abstract:
A higher solid coating composition comprises a solid resin mixture of polyol resin and alkyletherified melamine resin, 0.2∼10 parts by weight of an aliphatic sulfonic acid compound and 1∼100 parts by weight of a non-aqueous polymer dispersion based on 100 parts by weight of the resin mixture. The non-aqueous polymer dispersion consists of (a) organic solvent component, (b) particle component insoluble in the component (a), and (c) particular dispersion stabilizer component soluble in the component (a) and capable of stably dispersing the component (b) into the component (a).
