As early as 1934, the first usable acrylic resin dispersion was developed by German chemical company BASF, which was patented by Rohm and Haas. The synthetic paint was first used in the 1940s, combining some of the properties of oil and watercolor. Between 1946 and 1949, Leonard Bocour and Sam Golden invented a solution acrylic paint under the brand Magna paint. These were mineral spirit-based paints. Acrylics were made commercially available in the 1950s.
Following that development, Golden came up with a waterborne acrylic paint called "Aquatec". Otto Rhm invented acrylic resin, which was quickly transformed into acrylic paint. In 1953, the year that Rohm and Haas developed the first acrylic emulsions, Jose L. Gutierrez produced Politec Acrylic Artists' Colors in Mexico, and Henry Levinson of Cincinnati-based Permanent Pigments Co. produced Liquitex colors. These two product lines were the very first acrylic emulsion artists' paints.
Water-based acrylic paints were subsequently sold as latex house paints, as latex is the technical term for a suspension of polymer microparticles in water. Interior latex house paints tend to be a combination of binder (sometimes acrylic, vinyl, pva, and others), filler, pigment, and water. Exterior latex house paints may also be a co-polymer blend, but the best exterior water-based paints are 100% acrylic, due to elasticity and other factors. Vinyl, however, costs half of what 100% acrylic resins cost, and PVA (polyvinyl acetate) is even cheaper, so paint companies make many different combinations of them to match the market.
Soon after the water-based acrylic binders were introduced as house paints, artists and companies alike began to explore the potential of the new binders. Water-soluble artists' acrylic paints were sold commercially by Liquitex beginning in the 1950s, with modern high-viscosity paints becoming available in the early '60s. In 1963, Rowney (part of Daler-Rowney since 1983) was the first manufacturer to introduce artists acrylic paints in Europe, under the brand name "Cryla".
Before the 19th century, artists mixed their own paints, which allowed them to achieve the desired color and thickness, and to control the use of fillers, if any. While suitable media and raw pigments are available for the individual production of acrylic paint, hand mixing may not be practical because of the fast drying time and other technical issues.
Acrylic painters can modify the appearance, hardness, flexibility, texture, and other characteristics of the paint surface by using acrylic media or simply by adding water. Watercolor and oil painters also use various media, but the range of acrylic media is much greater. Acrylics have the ability to bond to many different surfaces, and media can be used to modify their binding characteristics. Acrylics can be used on paper, canvas and a range of other materials, however their use on engineered woods such as medium-density fiberboard can be problematic because of the porous nature of those surfaces. In these cases it is recommended that the surface first be sealed with an appropriate sealer. Acrylics can be applied in thin layers or washes to create effects that resemble watercolors and other water-based media. They can also be used to build thick layers of paintgel and molding paste media are sometimes used to create paintings with relief features. Acrylic paints are also used in hobbies such as train, car, house, and human models. People who make such models use acrylic paint to build facial features on dolls, or raised details on other types of models. Wet acrylic paint is easily removed from paint brushes and skin with water, whereas oil paints require the use of a hydrocarbon.
Acrylic paints are the most common paints used in grattage, a surrealist technique that became popular with the advent of acrylic paint. Acrylics are used for this purpose because they easily scrape or peel from a surface.
