Abstract
Radiation-polymerizable compositions are especially useful as or in a flush vehicle for making flushed pigments. The compositions contain at least one radiation-curable acrzylated resin component and a copolymerizable rheology modifier component.
Claims29
A flushed pigment composition comprising a pigment and a flushing vehicle, the flushed pigment being substantially free of water, the flushing vehicle comprising a substantially homogenous admixture of:
- a) two or more radiation-curable acrylated resins selected from the group consisting of acrylated epoxies, acrylated urethanes and acrylated polyesters;
- and
- b) a rheology modifying resin copolymerizable with radiation-curable acrylate resin when subjected to radiation.
A composition comprising a substantially homogenous admixture of:
- a) two or more radiation-curable acrylated resins selected from the group consisting of acrylated epoxies, acrylated urethanes and acrylated polyesters;
- and
- b) a rheology modifying resin copolymerizable with radiation curable acrylate resin when subjected to radiation.
A method for removing water from a presscake containing pigment and water the method comprising:
- providing a composition including
- (i) a radiation curable acrylated resin selected from the group consisting of acrylated epoxies, acrylated urethanes and acrylated polyesters;
- and
- (ii) a rheology modifying resin, contacting the composition with the presscake to provide a mixture;
- and separating water from the mixture.
A method for preparing a flushing vehicle, comprising the steps of forming a reaction mixture by adding (i) an epoxy component, (ii) an ethylenically unsaturated carboxylic acid or reactive derivative thereof, (iii) a fatty acid or reactive derivative thereof and (iv) a polyamide to a reaction vessel;
- and
- adding to the reaction mixture two or more radiation-curable acrylated resins selected from the group comprising acrylated epoxies, acrylated urethanes and acrylated polyesters.
