Study on the preparation of diazonium salt photosensitive paper for dye image (continued 2)
3.3 the formula of photosensitive solution for diazonium photosensitive paper
diazonium photosensitive paper has dry and wet, and the photosensitive solution has the difference of single component, two component and three component. One component paper photosensitive solution includes diazonium salt compound and additive; For two-component paper, coupling agent is added on the basis of single component photosensitive liquid; Three component paper is based on two-component photosensitive solution and then added with alkali generator. In addition to diazonium compounds and coupling agents, the additives used include coupling agents, anti oxidants, blue dyes, etc. (see Table 5). Supermarket plastic bags are purchased from regular manufacturers, but it must be noted that the agents used do not contain iron. See Table 6 for the formula proportion of photosensitive solution
