Ah!
You are right that the very first type of Acrylic was invented by BASF.
They just made a formulation to be commercially available artist paints.
Wiki quote:
"In 1953, the year that Rohm and Haas developed the first acrylic emulsions, Jose L. Gutierrez produced Politec Acrylic Artists' Colors in Mexico, and Permanent Pigments Co. of Cincinnati, Ohio, produced Liquitex colors. These two product lines were the very first acrylic emulsion artists' paints."
"Water-soluble artists' acrylic paints became commercially available in the 1950s, offered by Liquitex, with high-viscosity paints similar to those made today becoming available in the early 1960s."
This is what Liquitex claims:

"Liquitex was the first water-based acrylic paint created in 1955 and since then we have partnered with artists to ensure that we continually evolve and innovate"
"1956 -The first commercially available water-based fluid acrylic colors are developed, called Soft Body."
Anyway, they have been around a bit and have all kinds of product that are helpful.
