yep, I sell it. Benjamin Moore Chalkboard paint. product # 307-80. It's latex ( water cleanup ) and comes by the quart. It has very low odor that clears quickly. You need to apply minimum 2 coats, 3 is better.
Black only and costs $12.99/qt
Add one table spoon of vanilla extract to a gallon of paint. It will remind you of a cake in the oven when you paint. I use this trick when painting offices or other areas with lots of people to complain about the odor. I do not think this is any good to prevent actual paint allergies.
