Abstract: A method for dehydrating a porous cross-linked polymer conveniently to a low final water content is provided. A porous cross-linked polymer sheet is produced by a method which comprises causing a porous cross-linked polymer obtained by forming and polymerizing a water-in-oil type higher internal phase emulsion to be dehydrated by the use of non-woven fabric rolls furnished with an aspiration mechanism. Properly in this case, the porous cross-linked polymer is subjected to preliminary squeezing. In accordance with the present invention, a porous cross-linked polymer abounding in a water absorbing property to be dehydrated to a low final water content with a small number of rolls.

Abstract: A method for producing a porous cross-linked polymer sheet capable of slicing quickly is provided. This method comprises a step for obtaining a porous cross-linked polymer by forming and polymerizing an HIPE, a step for dehydrating the porous cross-linked polymer, and a step for subsequently slicing the dehydrated porous cross-linked polymer.

Abstract: The photo-curable liquid solder resist ink composition of the present invention mainly comprises a photo-polymerizable resin having sufficient molecular weight and (meth)acryloyl groups which are imparted by both of introduction of (meth)acryloyl groups into a novolak-type epoxy resin having 4 or more of benzene nuclei and polymerization using a chain-extension agent. The composition is useful for a photo-curable type resist, since it can produce a coated film excellent in tack free characteristic and resolution, and can produce a cured film excellent in heat resistance, adhesiveness, and chemical resistance. In addition, by reacting with an acid anhydride, development with alkalis becomes possible.

Abstract: The present invention provides a production method for a photo-sensitive resin, characterized in reacting a difunctional epoxy resin (B) having two epoxy groups in a molecule with carboxyl groups contained in a resin (A) having two or more (meth)acryloyl groups and at least one carboxyl group in a molecule. Since the photo-sensitive resin prepared by extending the resin (A) to a high molecular weight linearly via the difunctional epoxy resin (B) is obtained, a resist layer having an excellent tack-free property can be formed. Further, a resist layer irradiated with rays through a patterning film can be developed rapidly and correctly in an alkaline aqueous solution. Accordingly, it has been possible to provide the high-performance liquid photo-sensitive resin compositions useful for a solder resist used for producing printed circuit boards and for an electroless plating resist or useful for producing black matrices and color filters for liquid crystal displays.
