Colour, the Key to Distinction

A. S. Paterson Company has been selling colour since 1928. We understand colour. We work with leading colour pigment and dye manufacturers to assist our customers in selecting the perfect products and colours for their project. 

Colour constitutes a wide range of materials and effects. The two main categories are pigments and dyes. 

Pigments are large, insoluble molecules. To incorporate a colour pigment into a formulation, it must be dispersed into some medium. Pigments are available in dry forms but also in pre-dispersed forms making them easier to use. Pigments tend to give opacity to system.

Dyes are smaller molecules and can be dissolved in a specific solvent. A. S. Paterson Company has a wide range of dye powders soluble in water, alcohol and other solvents. Alternatively they may be available as pre-dissolved liquid dyes. Some of our dyes dissolve in melted plastic providing a transparent or translucent colour effect.

A. S. Paterson can help you create countless colour effects. Fluorescent dyes and pigments absorb ultraviolet light and immediately emit light in the visible part of the spectrum. Phosphorescent pigments absorb ultraviolet like fluorescent materials but phosphorescents store the energy and emit in the visible part of the spectrum gradually over time. Optical brighteners are a colourless version of fluorescent dyes.

Other Effects Include:

• Granite effects 
• Photochromic dyes
• Thermochromic dyes (change colour depending on temperature)
