摘要 |
A photographic film unit which includes first and second superposed sheets, and is processable by distributing a liquid between the sheets, is provided with liquid directing means that present a greater resistance to liquid flow in a longitudinal direction than in a transverse direction. Transverse barrier ridges, which are small compared to the depth of the liquid, are positioned between the sheets to inhibit the flow in the predetermined direction while flow continues uninhibited or is enhanced in the transverse direction along the ridges. Other embodiments employ stripes having different degrees of hydrophobicity.
