  • Patent number: 5061611
    Abstract: A method of preparing a light sensitive silver halide phtographic material is disclosed. The photographic material comprises a polyester support having a hydrophobic polymer layer containing a vinylidene chloride copolymer and at least one hydrophilic polymer layer. The method comprises steps of coating a hydrophilic polymer layer onto the polyester support, drying the layer until a water content of the layer reaches 60 wt %, and contacting the layer with air having a relative humidity of 5 to 25% for a period 5 seconds to 10 minutes. The photographic material according to the method has such a physical characteristics as dimensional stability for long time storage or anti-cracking of the photographic layer at the preparation period. It is suitable for printing use.

  • Patent number: 4851268
    Abstract: The start-up of a free-falling liquid curtain (12) in the coating of objects or a moving web (18) using curtain coaters is considerably improved by the controlled retraction of a catch pan device (30) positioned in close proximity to the moving web (18). The catch pan device which includes a primary lip (32), and a secondary lip (44), is positioned so that it can be retracted through the falling curtain at a predetermined speed and direction relative to the moving web (18). The device (30) is retracted at the start of a coating process so that the falling curtain is interrupted first by primary lip (32) and then secondary lip (44). Primary lip (32) prevents the coating liquids from flowing onto the moving web (18) during the start-up process and secondary lip (44) retains the coating liquids of an extended falling curtain resulting from contact between the curtain and primary lip (32).

  • Patent number: 4756988
    Abstract: Dry-film, negative-acting photoresist layers are used in the formation of many articles such as circuit boards, printing plates and the like. Laminable monolayers of photoresist can suffer from slow speeds, brittleness, variable adhesive characteristics, and narrow processing latitude during development and exposure. The use of a crosslinked or crosslinkable integral thermoplastic adhesive laer on the dry-film, negative-acting photoresist layer improves the properties and performance of the photoresist.
