Featured Positive Negatives. what are these ?

After seeing Evelyn's negatives in the Giveaway thread I remembered I had these I recovered from a house clearance.
The family lived in Hong Kong in the 50's and 60's and these images look to me of somewhere in Asia, possibly South East Asia
They are camera film measuring 5 x 4 inches 12 x 10cm, each are stored in its own plastic sleeve.

On the edge of each piece is " 95 Kodak Safety Film"
There is a small o between S and A of Safety.
They are in colour and not negative images.

 

Edit.
Those colour ranges are part of the film.

 

I wonder if they are colour plates for a book or brochure.

 

After reading Terry's Transparencies.

I found this

In photography, reversal film is a type of photographic film that produces a positive image on a transparent base. The film is processed to produce transparencies or diapositives (abbreviated as "diafilm" in many countries) instead of negatives and prints. Reversal film is produced in various sizes.

So like a projector slide film, only these are quite big.

 

Hi Fig.
I can't read it, I will see if I can enlarge it, on the same picture it says top right No9
bottom right says 1811
