Coloured films

Decorative self-coloured films can also be produced in sulphuric acid under conditions intermediate between normal and hard anodising. 

Homogeneity of dispersion and the homogeneous nature of the hybrid ORMOSIL systems result in intensely coloured films even at low thickness. Compared to organic polymers, the coloured hybrid films have enhanced mechanical properties such as greater hardness and stronger abrasion resistance. With respect to inorganic sol-gel films, hybrid films also have several advantages such as much better adhesion,... 

Moulded-in-colour film laminate technology for bumper fascias. 

Another non-paint approach is being developed by Mayco and DaimlerChrysler Corp, consisting of the extrusion of a glossy, coloured film. After thermoforming to the part shape, it is placed in an injection mould, and thermoplastic is injected behind it. Cost savings are estimated to be 5 to 12 per fascia. 

The two basic types of colour film are the colour reversal film for transparencies and the colour negative film used to produce prints on colour papers. 

Substituted vinylindolizines sometimes polymerize spontaneously and also copolymerize with styrene. Polymers of similar structure have been prepared by formation of indolizines on the polymer chain using methods outlined in Sections 3.08.3 and 3.08.6 (see Scheme 36 for an example). Moreover, indolizine dyes such as (214) have been bound to an ethyl acrylate/acrylic acid copolymer by heating to give dyes that do not migrate in photographic colour film emulsions. 

The emulsion used is similar for both black-and-white and colour film. 

Fig. 3.70 depicts the /i(pH) dependence of lyso PC films at po = 42 Pa, t = 30°C and constant ionic strength. In the pH range from 4.2. to 5.8, equilibrium silver-coloured films with mean h values of about 50 - 70 nm were formed. In some experiments, NBF of 7.6 nm thickness were formed, thus marking a fluctuation zone where both silver-coloured and NBF could be observed. Below pH = 4.1 only NBF formed.

The potentiostat is switched on to apply the potential across the electrodes and a coloured film is seen to form. Electrolysis is then continued until sufficient material is formed. The film is then washed with hexane and dried in a vacuum desiccator. 

Irradiate for 30 min. The polymer is obtained as a (depending on the composition) highly coloured film indicative of a cholesteric phase. 

Another application for colour separators is film printing. In this case, the primary colours are separated by means of mirrors, which produce three colour channels. Apertures mounted in each channel then provide continuous regulation of the light intensity for proper colour balance and production, as shown in Fig. 19. Poor quality colour film copies sometimes result from the overlapping sensitivity ranges... 

Dihydro-3//-pyrazol-3-ones are also used as couplers in colour photography. During the chro-mogenic development of the exposed colour film, they react with the developer, e.g. iV,iV-diethyl-p-phenylenediamine, to give a purple dye 6. 

I have no information on the foggy of colour films. Work will be undertaken later this year. I will keep you informed when I have some results. 

The samples in the buffer and a-amylase release less sodium fluoride than the plain buffer. These results indicate that there is not enough a-amylase present in the sample to contribute to an increase in d mdation time of the biopolymer. Overall the 5% non-coloured films display a constant release rate over die S w test period.

Adhesive materials used in vinyl lamination processes are discussed in detail. Characteristics of cold line epoxies and water-based emulsions are discussed. Information is presented on the lamination processes and applying the adhesive. Vinyls most commonly used are said to be Opaque Top Printed Laminate (OTPL)ZKlear View, Opaque Embossed (OE)/Solid Colour Film, Reverse Printed (RP) and Top Printed (TP).
