 Pigment is the natural coloring matter of animal or plant tissue. Pigments are used for coloring paint, ink, plastic, fabric, cosmetics, food and other materials.

What are hinges? Hinges are made of special archival tape, linen, or fine Japanese paper. With pressure sensitive tapes, prints cannot be glued or taped directly to a backing and for this purpose, hinges are used.

How does particle size affect a pigment's dispersibility? he sizes and shapes of particles of pigments have great impact on the colors of these pigments. But, these pigments are available in cluster form instead of individual form.

What are the lightfast properties of the pigments? The resistance characteristic of pigment against the fading after exposure to sunlight, is called as lightfast property of the pigments.

What are Pigment Sticks? Pigment Stick is an oil stick that transform oil painting into a whole new experience. These sticks consist of linseed oil, natural beeswax, and pigments. Generally, pigment sticks are highly fluid and very smooth.

What is the meaning of Luminescence? Luminescence is emission of light by a substance not resulting from heat; it is thus a form of cold body radiation.

What is the meaning of Fluorescence? Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation of a different wavelength.

What is the meaning of Phosphorescence? Phosphorescence is a specific type of photoluminescence related to fluorescence.

What is the meaning of Brightness? Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light.

How does TiO₂ provide opacity? When all of the visible light that falls on a surface, is scattered, then only opacity is appeared. Titanium dioxide is considered as an efficient light scatterer.

What is the relationship between Phosphorescence and Temperature? The light discharged by a phosphor, hugely depends upon the temperature.

Which chemical and physical factors affecting the light fastness of pigments and dyes? The lightfastness of the pigments and dyes do not depend upon the pigment or dye, but depends upon the whole system. These following factors affect the light fastness of pigments and dyes:

• Chemical as well as physical structure of these substrates.
• The concentration of dyes and pigments.
• The rate of diffusion of the volatile substances in the polymer.
• Distribution of wavelength of incident radiation.
• The atmospheric conditions like the humidity in the atmosphere and percentage of contaminants.
• Distribution of wavelength of the incident rays.

What makes one grade of TiO₂ different than another?

The particle size and surface treatment make the grade of TiO₂ different than another.

What are the prescribed directions while using dry pigments? For methods of using dry pigments (or other non-colored powdered additives) which require only as much mixing as is possible with a brush. These methods can be applied for solvent or water-based paints.

Will the organic color pigments stain the clothes or sheets? The color organic pigments are not stains nor these are dyes. So, if some stains arise in the clothes or sheets, then after some time these can be washed-out completely from any synthetic materials.
These stains can be removed very easily.

What is a mixed metal oxide (MMO)? MMO is a kind of inorganic pigment that contain more than one types iron metals in their oxide crystal structure.
