Bellini Eco Range Paper Developer, 500ml

Part of our Eco Range of developing chemicals, that we specially created for safer use in schools and colleges, this darkroom paper developer comes without harmful Hydroquinone and instead is based on Ascorbic Acid and Dimezone. You'll find improved handling and disposing after use when working with this chemical.

It's suitable for developing all black and white paper and produces a neutral tone, very quickly with intense blacks and absence of fogging.

The concentrate dilutes 1 + 9 with water and development is complete in 2 minutes.

Please note that Eco developers may be delivered as red/orange or yellow in colour.
 
The reason for this depends on two factors:
 
 1) Exposition to the light of products with ascorbic acid/dimezone is yellow at first when it is just mixed and bottled. Afterwards, it can become orange/red, but it does not affect the efficiency of the product (you might also find this on Neutol chemicals, for example, or with Bellini Eco film and Xtol Kodak once dissolved)
 
 2) Dimezone S presence of coloured molecules inside the product can sometimes appear in powder from white to deep orange. Alternatively, it can change the deep orange one to become like a red wine colour once dissolved.

This colour change doesn't affect the developer's efficiency or performance.
