Definitions
- the advantage of applying such a high web temperature is that one can use electrodes which are known to cause a poor potential distribution, e.g. needles, brush etc.
- Photo-sensitive layers containing silver-halide, colour filter layers and a protective layer were coated on the web by means of a slide coating method.
- the total quantity of emulsion solution was 95 cc/m 2 .
- the undermost layer which was a yellow colouring layer, had a gelatine concentration of 3.5 ⁇ 6 wt.%, a viscosity of 15 ⁇ 40 mPas (at a shear rate of 50 sec -1 ) and a flow rate of 10 cc/m 2 .
