Abstract
The composition having wet state clarity includes an aqueous latex binder combination of polymer particles with a diameter of less than 80 nanometers and a thickener. When glitter flakes are dispersed in these novel compositions in their wet state, they glitter more than conventional glitter compositions. Thus, they are more appealing to a consumer or an artist than conventional glitter compositions that tend to be cloudy or dull in their wet state.
Claims20
A composition in its wet state having a wet state clarity index (.DELTA.L) of less than 65 comprising:
- a first aqueous binder combination having said wet state clarity, said first combination comprising polymer particles having a diameter of less than 80 nanometers and a thickener or
- a second aqueous binder combination having said wet state clarity, said second combination comprising polymer particles having a diameter of less than 120 nanometers and a polyurethane thickener comprising an aqueous mixture of polyurethanes, which includes a first polyurethane with at least two end groups, wherein each end group comprises a terminal isocyanate and a polyether;
- a second polyurethane with at least two end groups, wherein each end group comprises a terminal isocyanate group and a non-functional group;
- and a third polyurethane with at least two end groups, wherein one end group comprises a terminal isocyanate and a polyether and one other end group comprises a terminal isocyanate and a non-functional group.
The composition of claim 5 wherein said polymer particles having a diameter of less than 120 nanometers comprise an addition polymerized copolymer of at least one ethylenically unsaturated monomer.
An artist, craft and hobby paint composition in its wet state having a wet state clarity index (.DELTA.L) of less than 65 comprising:
- a first aqueous binder combination comprising polymer particles having a diameter of less than 80 nanometers and a thickener.
An artist, craft and hobby paint composition in its wet state having a wet state clarity index (.DELTA.L) of less than 65 comprising:
- a aqueous binder combination comprising polymer particles having a diameter of less than 120 nanometers and a polyurethane thickener comprising at aqueous mixture of polyurethanes, which includes a first polyurethane with at least two end groups, wherein each end group comprises a terminal isocyanate and a polyether;
- a second polyurethane with at least two end groups, wherein each end group comprises a terminal isocyanate group and a non-functional group;
- and a third polyurethane with at least two end groups, wherein one end group comprises a terminal isocyanate and a polyether and one other end group comprises a terminal isocyanate and a non-functional group.
