Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
60 words
A printing ink composition comprising: a pigment and an aqueous polymer emulsion containing a first polymer network containing an active crosslinking agent which is intertwined on a molecular scale with a second polymer network wherein the second polymer differs from the first polymer and the first polymer comprises 5 to 95% on a solids by weight basis of the emulsion.
Claim 2
Dependent Claim
60 words
A printing ink composition comprising: a pigment and an aqueous polymer emulsion containing a first polymer network containing an active crosslinking agent which is intertwined on a molecular scale with a second polymer network wherein the second polymer differs from the first polymer and the first polymer comprises 5 to 95% on a solids by weight basis of the emulsion.
Claim 3
Dependent Claim
