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 3
Dependent Claim
105 words
