Tetenal Eukobrom AC Liquid 1 Litre Concentrate 1 + 9 B&W paper developer.
Eukobrom AC - Hydroquinone free Black and White Paper Developer is suitable for all B&W photographic papers, irrespective of whether they are traditional baryta-based or resin coated papers, e.g. Tetenal Vario. Either type of paper can be processed in dishes, drums or small desktop processing machines. Eukobrom AC produces deep blacks, clean whites and delivers a neutral image tone. The developer concentrate can be diluted in ratios from 1+4 to 1+9.
Eukobrom AC – A new developer with vitamin C?.
It really is true. Eukobrom AC, the new B&W paper developer from Tetenal is based on isoascorbate, better known as vitamin C. What’s the thinking behind this? Almost all conventional B&W paper developers contain the developing agent hydroquinone, a substance well-proven over many decades for the use in developer formulae.
In order to fulfil market-driven product demands for a developer that does not contain hydroquinone, Tetenal will be launching its new Eukobrom AC paper developer. This new product benefits from the many years of experience Tetenal has gained producing hydroquinone-free developer solutions for X-ray films, in particular for the medical imaging sector. With the new Eukobrom AC paper developer, users in the traditional photo laboratory sector now also have access to this technology.
The new Eukobrom AC formula requires no special hazard information to be printed on the label. Shipping the developer – even using parcel delivery services – is unproblematic; a decisive benefit for mail order companies in particular.
