    • A photographic support comprising a paper sheet coated with a polyolefin on both surfaces thereof, in which the paper sheet contains an alkyletene dimer mixtures, its alkyl chain composition being defined by the following equation: ##EQU1## in which [C.sub.14 and less] means the content of alkyl chains having carbon atoms of 14 and less; [C.sub.16 ] means the content of an alkyl chain having 16 carbon atoms; [C.sub.18 ] means the content of an alkyl chain having 18 carbon atoms; and [C.sub.20 and more] means the content of alkyl chains having carbon atoms of 20 and more, the alkyl chain contents being represented by % in number of the total alkyl chain content of the alkylketene dimer composition. The photographic support is effectively resistant to permeation of a developing solution.
    • 一种照相载体,其包含在其两个表面上涂覆有聚烯烃的纸片,其中所述纸片含有烷基二烯类二聚体混合物,其烷基链组合物由以下等式定义:其中[C14和更少]表示 碳原子数为14以下的烷基链的含量; [C16]是指具有16个碳原子的烷基链的含量; [C18]表示具有18个碳原子的烷基链的含量; [C20以上]表示碳原子数为20以上的烷基链的含量,烷基链含量以烷基烯酮二聚体组合物总烷基链含量的数量表示。 摄影载体有效地抵抗显影液的渗透。
