Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
105 words
In a non-turpentine, water-soluble, liquid paint medium for overglaze decoration of procelain the improvement of a medium consisting essentially of, by weight: 15 to 40% of polyvinyl pyrrolidone or a mixture of polyvinyl pyrrolidone and aqueous polyethylene oxide; 45 to 85% of ethylene glycol, propylene glycol, a mixture of ethylene glycol and propylene glycol, or a mixture of any of the foregoing with water; wherein the following ingredients are present in amounts up to: 5% of a non-ionic block copolymer of 2,000 molecular weight of which about 1,750 is propylene oxide and about 250 is ethylene oxide; 20% of butyl diglycol; and 5% of glycerol.
Claim 2
Dependent Claim
105 words
In a non-turpentine, water-soluble, liquid paint medium for overglaze decoration of procelain the improvement of a medium consisting essentially of, by weight: 15 to 40% of polyvinyl pyrrolidone or a mixture of polyvinyl pyrrolidone and aqueous polyethylene oxide; 45 to 85% of ethylene glycol, propylene glycol, a mixture of ethylene glycol and propylene glycol, or a mixture of any of the foregoing with water; wherein the following ingredients are present in amounts up to: 5% of a non-ionic block copolymer of 2,000 molecular weight of which about 1,750 is propylene oxide and about 250 is ethylene oxide; 20% of butyl diglycol; and 5% of glycerol.
