  • the use in an intermediatelayer per se is not, however, excluded from the present invention where the main adhesion problem is encountered with the intermediate product.
  • the thickness of the layer containing the polymer of the invention is less important than the-proportion of the polymer present. Generally speaking, however, considering the handling of photographic elements and the fact they are sometimes subjected to rough handling, itis preferred that the minimum thickness of the layer containing the polymer of the present invention, be it present alone or in mixture form with another substance, be about O.3 micron, and it is more preferred that the thickness be at least 0.5 micron. No significant improvement is obtained by'using a layer greater than 3 microns thick, and accordingly it is particularly pre: ferred to use a layer of from 0.5 to 3 microns in thickness.

Thereafter, the pressed film was stripped from the cellulose triacetate base, and the condition of the film sur- I face was examined. The surface of the film which had been closely attached to the base by being tightly contacted and adhered thereto had a rather smooth and glossy appearance to such an extent that it could not be clearly distinguished from other parts where no tight adhesion took place. The proportion of such glossy area to the total surface area in'percent was taken to evaluate the effectiveness of the top coating of this invention containing the specific polymer. The results are given in Table 1 below.
  • the tendency of surface tackiness or adhesiveness can be conveniently evaluated by comparing the size of the glossy area, i.e., the larger the percent of glossy area the greater the adhesion.
  • film B of this invention which is a photosensitive material having a surface layercontaining poly-Z-hydroxyethyl methacrylate has a more reduced surface tackiness than film A prepared according to a known method.
  • This type of film is usually formed as an intermediate product during the course of manufacturing multilayered color photographic materials, so that adherance problems which often take place during the hairdling thereof can be efficiently overcome by providing a surface layer containing a specific polymer of this invention, as seen in the case of test film B.
