Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
122 words
An aqueous coating composition comprising a binder of a modified, water-dilutable olefin polymer oil imide resin having an olefin polymer oil portion in the molecular weight range of from about 500 to about 2500, comprising at least 40% by weight of 1,4-polybutadiene oil, wherein the imide resin has a viscosity of from about 300 to about 1500 m Pas as measured on a 50% solution (weight/weight) in dibutyl glycol at 25° C. and contains from about 2.0 to about 3.5 milliequivalents of carboxyl groups per gram resin and from about 0.3 to about 2.0 milliequivalents of imide groups per gram resin and from about 10 to about 40 milliequivalents of imide groups for each 100 milliequivalents of imide groups and carboxyl groups.
Claim 2
Dependent Claim
122 words
An aqueous coating composition comprising a binder of a modified, water-dilutable olefin polymer oil imide resin having an olefin polymer oil portion in the molecular weight range of from about 500 to about 2500, comprising at least 40% by weight of 1,4-polybutadiene oil, wherein the imide resin has a viscosity of from about 300 to about 1500 m Pas as measured on a 50% solution (weight/weight) in dibutyl glycol at 25° C. and contains from about 2.0 to about 3.5 milliequivalents of carboxyl groups per gram resin and from about 0.3 to about 2.0 milliequivalents of imide groups per gram resin and from about 10 to about 40 milliequivalents of imide groups for each 100 milliequivalents of imide groups and carboxyl groups.
Claim 3
