Question

Cellulose acetate is raw material for

• A. Photographic films
• B. Tericot
• C. Shatter proof glass
• D. All the above

Answer 1

The correct option is A Photographic films

The acetate ester of cellulose is known as cellulose acetate. It is formed by the acetylation of the hydroxyl group of the cellulose. It is used as a film base in photography. It acts as a support medium for the photosensitive emulsion layer present on top of it. The photosensitive emulsion contains silver halide crystals. The part of the emulsion which receives the incident light turns light in color due to the reduction of silver halide and the unexposed are turns dark which leads to the creation of image.

So, the correct answer is option A.
