Organic pigments are organic compounds consisting of hydrocarbons. Organic pigments generally have clear shades and high color strength, depending on the manufacturing technology, pigment chemistry, and crystal structure.
Organic pigments generally have high color strength, bright shades, and can be either transparent or opaque. Heat resistance, light fastness, and solvent resistance are variable by the chemistry of the pigment.
