Definitions
- Suitable subbing layers capable of adhering hydrophilic layers such as gelatin-containing layers to cellulose triacetate and polyethylene terephthalate supports are well known from the silver halide photographic art.
- polyethylene and polyvinylidene chloride having a melting point of 110 and 190 C. respectively
- polyvinylidene chloride having a melting point of 110 and 190 C. respectively
- the following polymers with their respective glass-transition temperatureszpolystyrene (100 C.), polymethyl methacrylate (comprised between 70 and 105 C.), polyethyl methacrylate (50 C.), polyvinyl chloride (near 70 C.), polyacrylonitrile (near 100 C.), poly-N-vinylcarbazole (200 C.).
- Another Yprocedure which has proved to give very good results, is to use a type of recording material according to the present invention, wherein the recording layer con- ,contact-exposure as well as reflex exposureV can be applied.
- the intensity of exposure, the concentration of substances absorbing copying light and the thermoplastic polymer particles present in the recording layer are chosen in such a way, that the heating resulting from the absorption of the light rays directed to the original and strikingundifferentially the heat-sensitive layer causes at most (pracftic'allyno or) only aslight loss of water-permeability and/or water-solubility in the heat-,sensitive recording layer.
- the image-wise heat resulting from the image-wise reflected light must produce in the record-l ingY layer a practically useful level of differentiation in swelling power or solubility in water.
- Example l 1 40% aqueous dispersion of polyethylene as described in Example l 1 50 20% aqueous dispersion of polyethyl acrylate (soft latex) i 50 30% aqueous dispersion of silica having a particle size of 25 mm. 50 Water 750 Ethanol After drying at 60 C., the subbing layer obtained is coated with a heat-sensitive layer from the following composition in a proportion of 20 g./sq. m.:
- Example 1 10% aqueous solution of polyvinylpyrrolidone having an average molecular weight of 30,000 170 40% aqueous dispersion of polyethylene as described in Example 1 195 Aqueous carbon dispersion containing per 100 g.: 16 g. of carbon and 2 g. of low viscous poly(N vinylpyrrolidone) 50 Water 3% aqueous solution of the sodium salt of tetradecyl sulphate 65 After drying at 50 C., the material obtained is exposed and developed as in Example 1.
- thermosensitive recording layer was applied in a ratio of 20 g. per sqm. from the following composition:
- aqueous dispersion of polyethylene having a particle size of less than 0.1,u and an average molecular weight comprised between 15,000
