Abstract

Disclosed herein is a method for adjusting factory-made tintable paints at the point of sale by adding at least one gloss modifier to the factory-made tintable paints without substantially changing the amount of opacifying pigments in the tintable paints, so that a single color prescription can be used to tint the paints to a single color for any gloss or sheen. Such same color paints should have a color difference of less than 2.0 CIEDE2000 units. Also disclosed is an aqueous gloss reducer that contains mostly a matting agent with substantially no latex resin and substantially no opacifying pigments.

First claim

We claim:

1. A method for adjusting a factory-made tintable paint at a point of sale comprising the steps of
receiving the factory-made tintable paint in a plurality of containers, wherein each container comprises a first amount of opacifying pigment,
adjusting a finish of the factory-made tintable paint by adding at least one of a gloss reducer or a gloss enhancer into at least one container, wherein the gloss reducer comprises a matting agent and wherein the gloss enhancer comprises a latex resin to produce a second tintable paint,
wherein a second amount of opacifying pigment in the second tintable paint is substantially the same as the first amount,
wherein the gloss reducer comprises from about 25% to about 40% matting agent.

2. The method of claim 1 , wherein the first and second amounts of opacifying pigments are the same.

3. The method of claim 1 , wherein the gloss reducer comprises from about 25% to about 35% matting agent.

4. The method of claim 3 , wherein the gloss reducer comprises from about 30% to about 35% matting agent.

5. The method of claim 1 , wherein the gloss reducer comprises from about 8% to about 14% of rheological modifier.

6. The method of claim 5 , wherein the gloss reducer comprises from about 9% to about 13% of rheological modifier.

7. The method of claim 6 , wherein the gloss reducer comprises from about 10% to about 12% of rheological modifier.

8. The method of claim 1 , wherein the gloss reducer comprises from about 3% to about 7% of surfactants and dispersants.

9. The method of claim 1 , wherein the matting agent comprises a plurality of average sized silica particles.

10. The method of claim 1 , further comprises the step of adding at least one colorant into said at least one container to form a tinted paint.

11. The method of claim 1 , wherein the finish is selected from a group consisting of a high gloss, a semi-gloss, a satin, an eggshell and a flat/matte, wherein the high gloss has a gloss value at 60° between 70 and 85 or higher, wherein the semi-gloss has a gloss value at 60° between 35 and 70, wherein the satin has a gloss value at 60° between 20 and 35, wherein the eggshell has a gloss value at 60° between 10 and 25, and wherein the flat/matte has a gloss value at 60° between 0 and 10.

12. A method for adjusting tintable paint comprising the steps of
receiving or preparing the tintable paint,
adding at least one of a gloss reducer or a gloss enhancer to the tintable paint to produce a plurality of second tintable paints having different glosses,
tinting the plurality of second tintable paints with a single color prescription to produce a plurality of tinted paints,
wherein the color difference between any two tinted paints with different glosses is less than about 2.0 CIEDE2000 units.

13. The method of claim 12 , wherein the glosses are selected from a group consisting of a high gloss, a semi-gloss, a satin, an eggshell and a flat/matte,
wherein the high gloss has a gloss value at 60° between 70 and 85 or higher,
wherein the semi-gloss has a gloss value at 60° between 35 and 70,
wherein the satin has a gloss value at 60° between 20 and 35,
wherein the eggshell has a gloss value at 60° between 10 and 25, and
wherein the flat/matte has a gloss value at 60° between 0 and 10.

14. The method of claim 13 , wherein the color difference between any two tinted paints with different glosses is less than about 1.0 CIEDE2000 unit.

15. The method of claim 14 , wherein the color difference between any two tinted paints with different glosses is less than about 0.67 CIEDE2000 unit.

16. The method of claim 13 , wherein the gloss reducer comprises about 25% to about 40% matting agent.

17. The method of claim 16 , wherein the matting agent comprises a plurality of average sized silica particles.
