Abstract
The sheet consists of a base with coatings contg. (1) a colourless dyestuff precursor, which forms a dyestuff in the presence of acid, (2) a film-forming binder mixed with a compatible resin and (3) a phenolic cpd. and a film-forming binder. This gives exact and sharp reprodns. under thermographic conditions and is completely transparent. It is esp. suitable for the prodn. of slides for daylight projection. The binders and solvents for the 3 coatings are selected for minimal interaction during mfr. Coating (3) pref. also contains a resin. The resins soften in the 20-100 degrees C range and the phenolic cpd. has mol. wt. 140-240.
