Anthocyanin

== Description ==
Natural organic coloring compounds that occur in many seeds and flowers such as myrtle berries, blackberries, peonies, delphinium, petunia, and elderberry. Anthocyanins are water soluble glycosides and are usually red, blue, or violet in color. Examples of some anthocyanins are: pelargonidin, cyanidin, peonidin, delphinidin, petunidin, malvidin (Wallert 1993). These compounds do not form stable insoluble lake pigments.

Anthraquinone dye

== Description ==
An important class of synthetic vat dyes whose structure is based on anthraquinone. The resonance structure from the aromatic rings and the carbonyl groups provide the chromophore. Anthraquinone dyes were first sold commercially in 1901. They are vat dyes that must first be reduced with caustic soda and sodium hydrosulfite to produce a soluble compound, then once impregnated in the fiber and dried, they are oxidized with sodium perborate to form the original colorant. Anthraquinone dyes are lightfast and wash fast. Examples of anthraquinone dyes include anthrapyrimidine yellow (Pigment Yellow 108), anthraquinoid red (Pigment Red 177), and indanthrone blue (Pigment Blue 60). 
See also hydroxyanthraquinone.

Antiaris

== Description ==
1) A soft, lightweight wood obtained from the Antiaris africana tree native to the rain forests of western Africa. Antiaris is a tall, large tree that produces soft, lightweight timber with no visible growth rings. The wood has a medium to coarse texture with an uneven, roey grain and ribbonlike figuring. It can range in color from white to pale yellow to light gray. Antiaris is primarily used locally for plywood, furniture, interior finish, doors, and veneer. In Africa, the soft, lightweight wood was commonly used for dug-out canoes. 
2) The poisonous latex obtained from the upas tree, Antiaris toxicaria, native to Indonesia. Antiaris sap was used on the tips of blow gun darts. The lethal poison is soluble in acetone and chloroform, but insoluble in water.

Antiblocking agent

== Description ==
A substance that is added to the surface of another material to minimize adhesion. Antiblocking agents, such as chalk, talc, and clay, are added to the surface of vinyl and polyolefin films to prevent sticking when multiple layers are placed together. Antiblocking agents are also added to wax coatings to minimize bloom by forming an impenetrable layer on the surface.
