An improved latex composition is provided which has been found to exhibit superior ability to form a substantially uniform polymeric film when applied to a substrate. The composition is capable of being handled and applied to a substrate in the absence of excessive foaming. The aqueous composition includes as essential components, specific concentrations of a predominantly hydrophobic, normally liquid, predominantly hydrophobic, normally liquid, non-ionic ethylene oxide / propylene oxide block copolymer surfactant (eg, a hydrocarbon-based mineral oil). ). It is possible for the composition to be applied to a hydrophobic substrate (e.g., a polyester film substrate). The compositions of the present invention, after application to a substrate and volatilization of the water component, form a substantially uniform polymeric film that can serve as a coating or adhesive. |
