Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
148 words
In a pressure-tight spray can having a valved opening and containing a liquid paint composition and a volatile propellant for spraying said liquid composition through said valved opening, the improvement according to which said paint composition comprises: from 5 to 60 weight percent of a water soluble, neutralized resin film former obtained by reaction of (a) resin containing sufficient carboxyl groups to be water solubilized by reaction with a basic neutralizer to form a salt thereof, and (b) an amine or ammonia as said basic neutralizer for forming said salt with said resin, the amount of said neutralizer reacted with said resin to water solubilize said resin being equal to at least 60% of the theoretical neutralization requirement of said resin; and from 35 to 95 weight percent of a water-soluble solvent for said neutralized resin; said paint composition having a maximum of 8 weight percent of water.
