Abstract
Abstract Pigment preparations containing 3 to 80 percent by weight of an organic or inorganic pigment, 0.5 to 85 percent by weight of a resin containing carbodiimide groups and 0 to 75 percent of an organic solvent free from amino groups are used for pigmenting synthetic high-molecular materials, especially one-component and two-component polyurethane textile coating compositions.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
95 words
Process for the pigmentation of a synthetic macromolecular material comprising incorporating into said macromolecular material a pigment preparation comprising an inorganic or organic pigment in the amount of from 3 to 80% by weight of said preparation, a carbodiimide resin pigment vehicle in the amount of from 0.5 to 85% by weight of said preparation, and an organic solvent free from amino groups in the amount of from 0 to 75% by weight of said preparation, wherein additional functional groups on said carbodiimide resin comprise urethane, ester, ether or hydroxyl groups or a combination thereof.
Claim 2
Dependent Claim
95 words
Process for the pigmentation of a synthetic macromolecular material comprising incorporating into said macromolecular material a pigment preparation comprising an inorganic or organic pigment in the amount of from 3 to 80% by weight of said preparation, a carbodiimide resin pigment vehicle in the amount of from 0.5 to 85% by weight of said preparation, and an organic solvent free from amino groups in the amount of from 0 to 75% by weight of said preparation, wherein additional functional groups on said carbodiimide resin comprise urethane, ester, ether or hydroxyl groups or a combination thereof.
