Acrylic Paints were introduced to the artist's toolbox after WWII along with the rise of plastics across the urban landscape. Acrylics are plastic-based paints that are water-soluble and dry faster than oil paints. This makes acrylics ideal for situations when drying time, odor and solvent toxicity of oil paints must be avoided, like children's painting for instance. Not all acrylic paints are 100% non-toxic, but those that are will be labeled as such. Due to the expedited drying time for acrylic paints, the methods for acrylic painting differ. The fact that you can easily clean up and thin acrylic paints with water make them easier for home painting, as well.
