Patent number: 6432616Abstract: The present invention provides a water soluble polymer which is prepared by the following steps. First, a carboxyl group-containing polymer is reacted with an alkaline reagent so that a portion of the carboxyl groups are reacted in an amount sufficient to make the polymer water soluble. Then, the polymer obtained is reacted with an epoxide containing unsaturated bonds and/or heteroatoms so that 1 to 100 mole percent of the remaining carboxyl groups of the polymer are reacted with the epoxide to form ester groups via a ring-opening reaction of epoxides, wherein the heteroatom can be silicon, nitrogen, phosphorus or sulfur. The water soluble polymer of the present invention can be used as a photosensitive resin. When the photoresist composition is used for preparing printed ciruit boards, it exhibits high photosensitivity, good water dispersability, storage stability, and good adhesion to copper. In addition, the problem of sticking to the mask can be prevented.Type: GrantFiled: August 7, 2000Date of Patent: August 13, 2002Assignee: Industrial Technology Research InstituteInventors: Tsing-Tang Song, Shung-Jim Yang, Hsiu-Mei Chen, Yi-Hua Liu

Patent number: 6239189Abstract: A radiation-polymerizable composition contains at least one radiation curable acrylate resin oligomer prepared by reacting an alkoxylated polyol with a first acid component which includes an ethylenically unsaturated carboxylic acid; and a rheology modifier prepared by reacting a diepoxide with a second acid component which includes an ethylenically unsaturated carboxylic acid or reactive derivative thereof in the presence of a polyamide based on a polymerized fatty acid. The ethylenically unsaturated carboxylic acids of the first and second acid components are preferably acrylic acid or methacrylic acids. The diepoxide is preferably a diglycidyl ether such as bisphenol A. Colorants such as pigments or dyes optionally may be incorporated into the composition to form a printing ink which is curable by ultraviolet (UV) or electron beam radiation.Type: GrantFiled: March 27, 1998Date of Patent: May 29, 2001Assignee: Henkel CorporationInventors: Ramesh Narayan, Miguel Dones, Theresa Miller
