摘要： 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. Further, the coated layer formed by photo-curing the liquid photo-sensitive resin composition containing the polymer fine particles having a Tg of 20.degree. C. or lower has an advantage that the coated layer provides an excellent adhesion even if it is exposed to a heating process.

摘要： 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.

摘要： 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. According to this invention, by performing the step of dehydration prior to the conventional step of slicing, it is made possible to prevent the porous cross-linked polymer from adhering to the blade and the guides provided for a slicer, and allow the slicing to be attained quickly. By removing the salt from the polymer, it is further made possible to prevent a production device from gathering rust and the porous cross-linked polymer from permitting adhesion of rust thereto.
