  • the term "fatty acids” is intended to mean chain compounds having one carboxyl group, and include lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, montanic acid, oleic acid, linolenic acid, eleostearic acid, 12-hydroxystearic acid and the like.
  • Esters of fatty acids is intended to mean ester compounds of the above-mentioned fatty acids with onoalcohols, dialcohols or trialcohols, and typical examples thereof include stearic glycerin ester, palmitic glycerin ester and the like.
  • derivatives of fatty acids is intended to mean compounds containing one or more carboxyl groups in the molecular chain thereof exclusive of said fatty acids and esters thereof, and as examples thereof, there are mentioned phthalic acid, maleic acid, malic acid, succinic acid and the like.

  • silicone oil adsorbent compounds palmitic acid, myristic acid, stearic acid, aluminum stearate and zinc stearate are easily available and inexpensive.
  • 12-hydroxystearic acid has in its molecule a hydroxyl group as well as a carboxyl group, so that the silicone oil adsorption is better.
  • the overcoat layer contains at least one compound selected from the group consisting of polyhydric alcohols, higher alcohols and higher dialcohols. More specifically, preferable examples of the hydroxyl group containing compound useful as a silicone oil adsorbent in the present invention include dibenzylidenesorbitol and 1,10 decanediol .
  • the compounds exemplified above are suitable because they have a high capability of forming a hydrogen bond and a good silicone oil adsorption.
  • silicone oil adsorvent compounds are generally used alone, however, if desired, a mixture of two or more types of the compounds may also be used in combination.
  • Preferred compounds having a carboxyl group, as a silicone oil adsorbent to have a melting point of from 40 to 150°C and be solid at room temperature. When the melting point is below 40°C, the compound is liquid at room temperature, so that the resultant film has a pocr handleability. On the other hand, when the melting point exceeds 150°C, it becomes difficult to melt the compound at a temperature fed by the fixation roller, which results in difficulty in fixing the toner successfully.
  • the above silicone oil adsorbent compounds are suitably soluble in a non-solvent for the image-receiving layer from the viewpoint of production of thelovercoat layer. Specifically, in general, they are soluble in a lower alcohol, glycerin or the like, which is a non-solvent for the image receiving layer. In this case, the overcoat layer can be easily formed without detriment to the i age-receivinq layer at the time of coating.
  • the overcoat layer may further comprises a polyester resin, a styrene resin and the like in addition to the above described compounds having a carboxyl group or a hydroxyl group as a silicone oil adsorbent.

  • the use (as the additional resin) of a resin identical to or in the same type as the resin for the image-receiving layer is advantageous in that the improvement in adhesion is significant and no lowering in receptivity to the image is observed.
  • the thickness of the overcoat layer comprising a silicone oil adsorbent compound is preferably in the range of from 0.01 to 10 g/m " in terms of the coverage. When the coverage is less than 0.01 g/nr, the effect of adsorbing the silicone oil is small. On the other hand, when it exceeds 10 g/m", the light transmittance is likely to be lowered.
  • the coverage of the overcoat layer is more preferably in the range of from 0.1 to 1 g/m-, most preferably in the range of from 0.3 to 0.8 g/m". The regulation of the coverage of the overcoat layer in the above-described range offers a good balanced film construction and, at the same time, facilitates the formation of the overcoat layer.
  • the image-receiving film according to the above embodiment has an additional advantage over an image- receiving film without an overcoat layer, in that a satisfactory effect can be attained using a very small amount of silicone oil adsorbent (compound having a carboxyl group or compound having a hydroxyl group) .
  • the image-receiving film without an overcoat layer also has an additional advantage over the image- receiving film of the above embodiment in that the simple layer construction simlifies the production process and a thin film can be provided.
  • Fig. 2 is a schematic cross-sectional view of another preferred embodiment of the image-receiving film of the present invention.
  • the image-receiving film according to this embodiment comprises a transparent substrate 1 and, on one surface of the substrate, an image-receiving layer 4 comprising a silicone oil adsorbent (compound having a carboxyl group or compound having a hydroxyl group) .

  • the useful amount of the silicone oil adsorbent compound added is from 1 to 1000 parts by weight based on 100 parts by weight of the remaining resin in the image-receiving layer. When it is less than 1 part by weight, the intended effect cannot be attained; when it exceeds 1000 parts by weight, the light transmittance is lowered, which is likely to cause a lowering in image quality and haze development.
  • the preferred amount of the compound (s) is from 10 to 500 parts by weight, most preferably in the range of from 30 to 300 parts by weight.
  • Fig. 3 is a schematic cross-sectional view of a further preferred embodiment of the image-receiving film of the present invention.
  • the image-receiving film according to this embodiment has the same construction as in Fig. 1, except that the image-receiving layer 2 provided on the transparent substrate 1 contains fine particles 5 (silica particles in this case) and is covered with the overcoat layer 3.

  • silicone oil adsorbent compound having a carboxyl group or compound having a hydroxyl group.
  • the silicone oil adsorbent compounds are incorporated into the image-receiving film in this way, the particles are protruded on the surface of image- receiving film. The intended effect can be attained even when the amount of the silicone oil adsorbent compound (s) added is small, and the effect is maintained, so that there is no fear of the light transmittance being lowered.
  • silica particles may be incorporated into the overcoat layer instead of or in addition to the image receiving layer. This is suitable from the viewpoint of reducing the oil pooling phenomenon and improving the feedability of the film, and when added to the overcoat layer, the effect seen from the particles is larger for the amount added.
  • the antistatic effect of the film can be enhanced by adding an antistatic agent to any layer constituting the image-receiving film.
  • useful antistatic agents include quaternary ammonium salts and various clay particles.
