Abstract

PURPOSE:To obtain the titled protective material outstanding in protectivity and workability, by drying a polyurethane emulsion made up of a hydrophobic polyurethane polymer, hydrophilic polyurethane polymer, organic solvent and water. CONSTITUTION:The objective protective material suitable for application on glass bottles for beverages in vending machines can be obtained by either drying or, preferably, coating on a non-porous plastic film, a polyurethane emulsion which is prepared by agitating a mixture of (A) pref. 5-20wt.% of a hydrophobic polyurethane polymer, (B) pref. 1-3wt.% of a hydrophilic polyurethane polymer [pref. of formula (R is hydrophobic polyisocyanate-terminated prepolymer domain; E is chain extender domain; G is polyoxyethylene domain; n is 1-3)], (C) pref. 35-75wt.% of an organic solvent (e.g. methyl ethyl ketone) and (D) pref. 20-40wt.% of water.
