Patent number: 6869484Abstract: A continuous feed coater for coating a length of substrate with vaporized or sprayed material, is disclosed. A specific example is a roll-to-roll coater which includes two lower supply rollers for supporting two webs of uncoated material, and two upper take-up rollers for supporting the webs after they are coated. A central web-support forms a plenum that acts as a deposition chimney or chamber by bringing the two webs into close proximity to each other to form two large walls of the plenum. The ends of the webs are sealed using side dams to form the chimney with a rectangular cross section such that the vapor cannot exit from the edges of the material. The vaporized coating constituents to be deposited on the rolled material are directed into the deposition plenum from a coating material supply source located at the bottom of the plenum, and are exhausted through the top of the plenum.Type: GrantFiled: September 15, 2001Date of Patent: March 22, 2005Assignee: Shipley Company, L.L.C.Inventors: Andrew T. Hunt, Wayne Neilson, Miodrag Oljaca, Edward J. Reardon, Tzyy-Jiuan Jan Hwang, William D. Danielson, Jr., James D. Huggins, David E. Bane, Ian H. Campbell, Yibin Xue

Patent number: 5609991Abstract: A photoimageable composition, useful as a photoresist for forming a printed circuit board, is both alkaline aqueous developable but, subsequent to exposure and development, is processable in highly alkaline environments, such as additive plating baths and ammoniacal etchants. The photoimageable composition is tack-free and is resistance to polymerization inhibition by oxygen, and is therefore particularly suitable for contact printing. The photoimageable composition comprises A) between about 25 and about 75 wt % of a binder polymer, B) between about 20 and about 60 wt % of a photopolymerizeable material which is a multifunctional photopolymerizeable monomer or short chain oligomer, and C) between about 2 and about 20 wt % of a photoimageable chemical system, the weight percentages being based on the total weight of components A)-C).Type: GrantFiled: August 3, 1995Date of Patent: March 11, 1997Assignee: Morton International, Inc.Inventors: James J.
