Final answer:
The recent invention described is Acrylic Painting, notable for its fast-drying properties, transparent films of color, and ease of use. Acrylic paint became widely used in the art world since its commercial availability in the 1950s, offering an alternative to oil paints with its water solubility and once dry, water imperviousness.
Step-by-step explanation:
The invention being described in the question is Acrylic Painting, which refers to paintings made with acrylic paint. Acrylic paint is a mixture of pigment suspended in an acrylic polymer emulsion, and it has been a significant medium since it became commercially available in the 1950s. This type of painting is known for its fast-drying qualities, ability to be mixed with water and other acrylics, and transparent films of color that it can provide. Unlike oil paints, which require chemicals to be cleaned up, acrylic paint can be cleaned up with water and does not need solvents. Additionally, when dry, it is impervious to water, unlike watercolors. Acrylic paint has had a considerable impact on the art world, giving artists the versatility of oils without the expense and toxicity, and has been particularly favored in techniques like color field painting where large, flat areas of color are desired.
