A process of making the polyurethane/acrylic hybrid dispersion.
First claim
Opening claim text (preview).
What is claimed is: 1. A polyurethane/acrylic hybrid dispersion comprising a polyurethane dispersion, acrylic monomers, a pigment, and ethylenically unsaturated phosphorus containing monomers, wherein the polyurethane/acrylic hybrid dispersion is made by polymerizing in a polyurethane dispersion, acrylic monomers, a pigment, and ethylenically unsaturated phosphorus containing monomers, wherein the weight ratio of the solid content of the polyurethane dispersion to that of the acrylic monomers and the ethylenically unsaturated phosphorus containing monomers is from 3:7 to 7:3. 2. The polyurethane/acrylic hybrid dispersion according to claim 1 wherein the ethylenically unsaturated phosphorus containing monomers are present from 0.3 wt. % to 2.0 wt. % based on the total combined weight of the acrylic monomers and the ethylenically unsaturated phosphorus containing monomers. 3. The polyurethane/acrylic hybrid dispersion according to claim 2 wherein the ethylenically unsaturated phosphorus containing monomers are present from 0.5 wt. % to 1.5 wt. % based on the total combined weight of the acrylic monomers and the ethylenically unsaturated phosphorus containing monomers. 4. The polyurethane/acrylic hybrid dispersion of claim 3 wherein the ethylenically unsaturated phosphorus containing monomers comprise phosphoethylmethacrylates. 5. The polyurethane/acrylic hybrid dispersion of claim 2 wherein the ethylenically unsaturated phosphorus containing monomers comprise phosphoethylmethacrylates. 6. The polyurethane/acrylic hybrid according to claim 1 wherein the ethylenically unsaturated phosphorus containing monomers are selected from phosphoalkyl (meth)acrylates, phosphoalkoxy (meth)acrylates, salts of phosphoalkyl (meth)acrylates, salts of phosphoalkoxy (meth)acrylates, and the mixture thereof. 7. The polyurethane/acrylic hybrid dispersion of claim 6 wherein the ethylenically unsaturated phosphorus containing monomers comprise phosphoethylmethacrylates. 8. The polyurethane/acrylic hybrid dispersion according to claim 1 wherein the weight ratio of the solid content of the polyurethane dispersion to that of the acrylic monomers and the ethylenically unsaturated phosphorus containing monomers is from 4:6 to 6:4. 9. The polyurethane/acrylic hybrid dispersion of claim 8 wherein the ethylenically unsaturated phosphorus containing monomers comprise phosphoethylmethacrylates. 10. The polyurethane/acrylic hybrid dispersion of claim 1 wherein the ethylenically unsaturated phosphorus containing monomers comprise phosphoethylmethacrylates. 11. A process of making a polyurethane/acrylic hybrid dispersion comprising polymerizing in a polyurethane dispersion, acrylic monomers, a pigment, and ethylenically unsaturated phosphorus containing monomers, wherein the weight ratio of the solid content of the polyurethane dispersion to that of the acrylic monomers and the ethylenically unsaturated phosphorus containing monomers is from 3:7 to 7:3. 12. The process according to claim 11 wherein the ethylenically unsaturated phosphorus containing monomers are present from 0.3 wt. % to 2.0 wt. % based on the total combined weight of the acrylic monomers and the ethylenically unsaturated phosphorus containing monomers. 13. The process according to claim 11 wherein the ethylenically unsaturated phosphorus containing monomers are selected from phosphoalkyl (meth)acrylates, phosphoalkoxy (meth)acrylates, salts of phosphoalkyl (meth)acrylates, salts of phosphoalkoxy (meth)acrylates, and the mixture thereof. 14. The process according to claim 11 wherein the weight ratio of the solid content of the polyurethane dispersion to that of the acrylic monomers and the ethylenically unsaturated phosphorus containing monomers is from 4:6 to 6:4.
