Cellulose acetate is raw material for

Options

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

Answer

### Step-by-Step Solution:

1. **Understanding Cellulose Acetate**:
- Cellulose acetate is an ester derived from cellulose. It is formed through a chemical process known as acetylation, where the hydroxyl groups of cellulose are replaced with acetyl groups.

2. **Identifying Uses of Cellulose Acetate**:
- Cellulose acetate is primarily used in various applications, one of the most notable being in the production of photographic films.

3. **Role in Photography**:
- In photography, cellulose acetate serves as a film base. It acts as a support medium for photosensitive emulsions, which are crucial for capturing images.

4. **Function of Photosensitive Emulsion**:
- The photosensitive emulsion on the film contains silver halide crystals. When exposed to light, these crystals undergo a reduction process that allows the film to capture the image.

5. **Conclusion**:
- Given its significant role in the production of photographic films, we can conclude that cellulose acetate is indeed a raw material for photographic films.

### Final Answer:
Cellulose acetate is a raw material for photographic films.
