It can be used alone or in combination with hydroquinone, and the effect is very good. The relative reducing power of this product is about 20 times that of hydroquinone. The developer made of this product and hydroquinone in the ratio of 1: 2-4 is called MQ developer; if formulated with partial acid, it can be used as a microparticle developer (film sensitivity is 1/2).
