Abstract: High quality, aqueous-based, heat-curable, primer coating compositions substantially free of organic solvents are disclosed. Said primer compositions include (a) from about 30% to about 75% by weight of a resinous binder which is a mixture of (i) from about 10% to about 60% by weight of finely divided epoxy resin, including blends thereof, having a weight average molecular weight of from about 900 to about 8000 and an epoxide equivalent weight of from about 450 to about 4000, and (ii) from about 5% to about 30% by weight of dispersible, methylated methoxymethyl urea resin which is a crosslinking agent having a formaldehyde:urea molar ratio of 2.2-2.8:1, methanol:urea molar ratio of 1.3-2.0:1, and toluene tolerance of at least 50 weight percent, (b) from about 25% to about 70% by weight of water, and, if desired, (c) up to about 30% by weight of pigment, including a combination of pigments.

Abstract: The present invention relates to a glass bottle coated with a multi-layer protective film comprising high polymer substances, and a method for producing such a coated glass bottle. More particularly, the invention is concerned with a glass bottle designed for containing carbonated beverages such as soft drinks or beer, wherein the beverages must be maintained under pressurized conditions, said bottle being coated on its outer wall by spraying or otherwise applying a plurality of protective films. Still more particularly, the present invention is directed to a "return-type" glass bottle for carbonated beverages such as soft drinks and beer, wherein the glass bottles are designed for repeated use, each cycle of which requires washing and sterilizing steps prior to filling.
