MANUFACTURE OF PHOTOGRAPHIC SENSITIVE MATERIAL

PURPOSE:To enhance quality without causing defects, such as repelling of a coating fluid, by adjusting the dynamic surface tension of the coating fluid to be used for the uppermost layer lower by a specified value than the minimum of that among those of the coating fluids to be used for other layers...

Zusammenfassung:	PURPOSE:To enhance quality without causing defects, such as repelling of a coating fluid, by adjusting the dynamic surface tension of the coating fluid to be used for the uppermost layer lower by a specified value than the minimum of that among those of the coating fluids to be used for other layers. CONSTITUTION:The laminates composed of >=3 liquid layers have an intermediate layer having the dynamic surface tension substantially inverted are fed on a traveling support to coat the support, and the dynamic surface tension of the coating fluid of the uppermost layer is adjusted by >=5 dyne/cm lower than the minimum of that among those of the coating fluids of the other layers, and that the dynamic surface tension is substantially inverted in the intermediate layer means that the dynamic surface tension does not gradually decrease toward the uppermost layer but it rises in the intermediate layer, thus permitting problems on defective coating, especially uneven coating and repelling of the coating fluid to be solved.
