Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 105 words
A SURFACE COATING COMPOSITION WHICH COMPRISES A MIXTURE OF AN ALKYD RESIN, AN AROMATIC, ALIPHATIC OR CYCLOALIPHATIC HYDROCARBON SOLVENT AND A NON-AROMATIC PETROLEUM RESIN WHICH IS THE PRODUCT OF POLYMERIZATION OF A PETROLEUM FRACTION BOILING IN THE RANGE -10* TO 80*C. DERIVED FROM A STREAM CRACKED NAPHTHA OR GAS OIL AND CONTAINING MORE THAN ONE HYDROCARBON SELECTED FROM THE GROUP CONSISTING OF BUTENE-1, BUTENE-2, ISOBUTENE, ISOPRENE, CIS-PIPERYLENE, TRANSPIPERYLENE, N-PENTANE, ISOPENTANE, PENTENE-1, CYCLOPENTADIENE, DICYCLOPENTADIENE, TRANSPENTENE-2, 2-METHYLBUTENE-2, CYCLOPENTENE AND CYCLOPENTANE AND WHEREIN THE COMPOSITION CONTAINS 25 TO 85% BY WEIGHT ALKYD PLUS PETROLEUM RESIN AND THE PETROLEUM RESIN IS 5 TO 15% BY WEIGHT OF THE ALKYD.
Claim 2
Dependent Claim 105 words
A SURFACE COATING COMPOSITION WHICH COMPRISES A MIXTURE OF AN ALKYD RESIN, AN AROMATIC, ALIPHATIC OR CYCLOALIPHATIC HYDROCARBON SOLVENT AND A NON-AROMATIC PETROLEUM RESIN WHICH IS THE PRODUCT OF POLYMERIZATION OF A PETROLEUM FRACTION BOILING IN THE RANGE -10* TO 80*C. DERIVED FROM A STREAM CRACKED NAPHTHA OR GAS OIL AND CONTAINING MORE THAN ONE HYDROCARBON SELECTED FROM THE GROUP CONSISTING OF BUTENE-1, BUTENE-2, ISOBUTENE, ISOPRENE, CIS-PIPERYLENE, TRANSPIPERYLENE, N-PENTANE, ISOPENTANE, PENTENE-1, CYCLOPENTADIENE, DICYCLOPENTADIENE, TRANSPENTENE-2, 2-METHYLBUTENE-2, CYCLOPENTENE AND CYCLOPENTANE AND WHEREIN THE COMPOSITION CONTAINS 25 TO 85% BY WEIGHT ALKYD PLUS PETROLEUM RESIN AND THE PETROLEUM RESIN IS 5 TO 15% BY WEIGHT OF THE ALKYD.
Claim 3
Dependent Claim 105 words
A surface coating composition which comprises a mixture of an alkyd resin, an aromatic, aliphatic or cycloaliphatic hydrocarbon solvent and a non-aromatic petroleum resin which is the product of polymerization of a petroleum fraction boiling in the range -10* to 80*C. derived from a steam cracked naphtha or gas oil and containing more than one hydrocarbon selected from the group consisting of butene-1, butene-2, isobutene, isoprene, cis-piperylene, trans-piperylene, n-pentane, isopentane, pentene-1, cyclopentadiene, dicyclopentadiene, transpentene-2, 2-methylbutene-2, cyclopentene and cyclopentane and wherein the composition contains 25 to 85% by weight alkyd plus petroleum resin and the petroleum resin is 5 to 15% by weight of the alkyd.
Claim 4
Dependent Claim 105 words
A surface coating composition which comprises a mixture of an alkyd resin, an aromatic, aliphatic or cycloaliphatic hydrocarbon solvent and a non-aromatic petroleum resin which is the product of polymerization of a petroleum fraction boiling in the range -10* to 80*C. derived from a steam cracked naphtha or gas oil and containing more than one hydrocarbon selected from the group consisting of butene-1, butene-2, isobutene, isoprene, cis-piperylene, trans-piperylene, n-pentane, isopentane, pentene-1, cyclopentadiene, dicyclopentadiene, transpentene-2, 2-methylbutene-2, cyclopentene and cyclopentane and wherein the composition contains 25 to 85% by weight alkyd plus petroleum resin and the petroleum resin is 5 to 15% by weight of the alkyd.
Claim 5
Dependent Claim 32 words
The composition of claim 1 in which the petroleum fraction contains more than one hydrocarbon selected from the group consisting of isoprene, cis and transpiperylene, pentene-1, cyclopentadiene, dicyclopentadiene, trans-pentene-2, 2-methylbutene-2 and cyclopentene.
Claim 6
Dependent Claim 17 words
The composition of claim 1 in which the petroleum fraction is polymerised using a Friedel Crafts catalyst.
Claim 7
Dependent Claim 57 words
The composition of claim 1 in which the alkyd resin is obtained by the partial acidolysis or alcoholysis of a fatty acid glyceride with a di- or polybasic acid or a di- or polyhydric alcohol followed by reaction of the acidolysis product with a di-or polyhydric alcohol and the alcoholysis product with a di- or polybasic acid.
Claim 8
Dependent Claim 23 words
The composition of claim 4 in which the fatty acid glyceride is soya bean oil, dehydrated castor oil, tung oil or fish oil.
Claim 9
Dependent Claim 21 words
The composition of claim 4 in which the acid is o-phthalic acid, isophthalic acid, terephthalic acid, maleic acid or fumaric acid.
Claim 10
Dependent Claim 25 words
